Abstract

PROBLEM TO BE SOLVED: To secure a high compression ratio and improve combustion efficiency by forming a space which is released in a scavenging process and closed in a compression process by means of a piston valve in a two-cycle gasoline engine. SOLUTION: A two-cycle gasoline engine has an intake port 1, an exhaust port 2, and an exhaust port 3. In such an engine, a hollow space 6 which is opened in a scavenging process and closed in a compression process by means of a piston valve 4 is formed communicatably with a combustion chamber. An intake valve 5 exclusive for air is opened in an expansion process and closed in an exhaust process, the scavenging process and a compresion process. It is thus possible to secure a high compression ratio and generate large power and torque. The piston valve 4 may be replaced with a rotary valve. A supercharger can be connected to an intake port which is opened or closed by means of the intake valve 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine for obtaining a high compression ratio by using a piston valve and a rotary valve in a two-cycle gasoline engine and a two-cycle diesel engine, and an auxiliary device for the engine.

[0002]

2. Description of the Related Art Conventionally, 2-cycle gasoline engine, 2
In a cycle diesel engine, scavenging → compression → combustion → exhaust was performed in two strokes (two steps).

[0003]

In the conventional 2-cycle gasoline engine and 2-cycle diesel engine, a 4-cycle engine (gasoline and diesel),
Compared with a 6-cycle engine (gasoline and diesel, 1990 Patent Application No. 417964), there were problems that the compression ratio was low and the combustion efficiency was poor.

The present invention is a two-stroke gasoline engine,
The purpose of the engine is to obtain a high compression ratio by using a piston valve and a rotary valve in a two-cycle diesel engine. Further, when the engine is used, the same displacement can be obtained depending on the explosion speed of the engine. The purpose is to obtain more power and torque at the same rotation speed.

[0005]

In order to achieve the above object, a piston valve and a rotary valve are used in the two-cycle gasoline engine and the two-cycle diesel engine of the present invention to open in the scavenging process and to open in the compression process. Close, valve (piston valve), mouth (rotary valve)
Is provided.

[0006] There is nothing in the valve and the air port that is opened and closed by the piston valve and the rotary valve (air mixture or
Place where the air temporarily stagnates).

In addition, when there are multiple cylinders, an empty space is connected to one space.

Then, as a countermeasure against closing the valve in the compression process and opening the air port too much, during the expansion process, the air-fuel mixture or air expands too much, and conversely opens before it becomes a resistance to rotation. An intake valve and an intake port for air, which are closed in the exhaust process, the scavenging process, or the compression process, are provided.

In addition, the intake of the air-fuel mixture, the intake of the air, and the intake valve for exclusive use of the air, the opening / closing engine of the intake port, the turbocharger, the supercharger, etc.
Install the supercharger.

[0010]

The two-cycle gasoline engine and the two-cycle diesel engine configured as described above are opened and closed by a piston valve and a rotary valve, and opened in a scavenging process,
It is easy to increase the compression ratio due to the fact that it is closed in the compression process and has an empty space.

Also, in the case of multi-cylinder, the stagnant time of air-fuel mixture and air compressed into an empty space due to connecting empty spaces to one is determined by the same engine explosion speed. If so, it can be shortened, and depending on the number of cylinders and the rotation angle of the crank shaft that opens and closes an empty space, it opens in the scavenging process and closes in the compression process. The air-fuel mixture does not compress the air-fuel mixture or the air alone, and goes in and out.

As a measure against excessive opening of the valve and the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. A higher compression ratio can be obtained by providing an intake valve and intake port exclusively for air that are opened and closed in the exhaust process, the scavenging process, or the compression process.

Also, due to the supercharger, such as a turbocharger, a supercharger, etc., being attached during the air-fuel mixture intake process and the air intake process of the above engine,
With the same displacement and same explosion speed, more power torque can be obtained.

Further, as a measure against excessive opening of the valve or the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. Since air is pressurized by attaching a supercharger such as a turbocharger or supercharger to the intake valve and intake port dedicated to air that is opened, closed in the exhaust process, scavenging process, or compression process, Backflow of exhaust gas can be easily prevented, opening / closing timing can be easily adjusted, and a large amount of exhaust gas can be removed.

In the conventional 2-cycle gasoline engine and 2-cycle diesel engine, a 4-cycle engine (gasoline and diesel),
Compared with a 6-cycle engine (gasoline and diesel, 1990 Patent Application No. 417964), there were problems that the compression ratio was low and the combustion efficiency was poor.

The present invention is a two-stroke gasoline engine,
The purpose of the engine is to obtain a high compression ratio by using a piston valve and a rotary valve in a two-cycle diesel engine. Further, when the engine is used, the same displacement can be obtained depending on the explosion speed of the engine. The purpose is to obtain more power and torque at the same rotation speed.

[0005]

In order to achieve the above object, a piston valve and a rotary valve are used in the two-cycle gasoline engine and the two-cycle diesel engine of the present invention to open in the scavenging process and to open in the compression process. Close, valve (piston valve), mouth (rotary valve)
Is provided.

[0006] There is nothing in the valve and the air port that is opened and closed by the piston valve and the rotary valve (air mixture or
Place where the air temporarily stagnates).

In addition, when there are multiple cylinders, an empty space is connected to one space.

Then, as a countermeasure against closing the valve in the compression process and opening the air port too much, during the expansion process, the air-fuel mixture or air expands too much, and conversely opens before it becomes a resistance to rotation. An air intake valve and an intake port dedicated to air, which are closed in the exhaust process, the scavenging process, or the compression process, are provided.

In addition, the intake of the air-fuel mixture, the intake of the air, and the intake valve for exclusive use of the air, the opening / closing engine of the intake port, the turbocharger, the supercharger, etc.

Also, in the case of multi-cylinder, the stagnant time of air-fuel mixture and air compressed into an empty space due to connecting empty spaces to one is determined by the same engine explosion speed. If so, it can be shortened, and depending on the number of cylinders and the rotation angle of the crank shaft that opens and closes an empty space, it opens in the scavenging process and closes in the compression process. The air-fuel mixture does not compress the air-fuel mixture or the air alone, and goes in and out.

As a measure against excessive opening of the valve and the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. A higher compression ratio can be obtained by providing an intake valve and intake port exclusively for air that are opened and closed in the exhaust process, the scavenging process, or the compression process.

Also, due to the supercharger, such as a turbocharger, a supercharger, etc., being attached during the air-fuel mixture intake process and the air intake process of the above engine,
With the same displacement and same explosion speed, more power torque can be obtained.

Further, as a measure against excessive opening of the valve or the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. Since air is pressurized by attaching a supercharger such as a turbocharger or supercharger to the intake valve and intake port dedicated to air that is opened, closed in the exhaust process, scavenging process, or compression process, Backflow of exhaust gas can be easily prevented, opening / closing timing can be easily adjusted, and a large amount of exhaust gas can be removed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine for obtaining a high compression ratio by using a piston valve and a rotary valve in a two-cycle gasoline engine and a two-cycle diesel engine, and an auxiliary device for the engine.

[0002]

2. Description of the Related Art Conventionally, 2-cycle gasoline engine, 2
In a cycle diesel engine, scavenging → compression → combustion → exhaust was performed in two strokes (two steps).

[0003]

In the conventional 2-cycle gasoline engine and 2-cycle diesel engine, a 4-cycle engine (gasoline and diesel),
Compared with a 6-cycle engine (gasoline and diesel, 1990 Patent Application No. 417964), there were problems that the compression ratio was low and the combustion efficiency was poor.

The present invention is a two-stroke gasoline engine,
The purpose of the engine is to obtain a high compression ratio by using a piston valve and a rotary valve in a two-cycle diesel engine. Further, when the engine is used, the same displacement can be obtained depending on the explosion speed of the engine. The purpose is to obtain more power and torque at the same rotation speed.

[0005]

In order to achieve the above object, a piston valve and a rotary valve are used in the two-cycle gasoline engine and the two-cycle diesel engine of the present invention to open in the scavenging process and to open in the compression process. Close, valve (piston valve), mouth (rotary valve)
Is provided.

[0006] There is nothing in the valve and the air port that is opened and closed by the piston valve and the rotary valve (air mixture or
Place where the air temporarily stagnates).

In addition, when there are multiple cylinders, an empty space is connected to one space.

Then, as a countermeasure against closing the valve in the compression process and opening the air port too much, during the expansion process, the air-fuel mixture or air expands too much, and conversely opens before it becomes a resistance to rotation. An intake valve and an intake port for air, which are closed in the exhaust process, the scavenging process, or the compression process, are provided.

In addition, the intake of the air-fuel mixture, the intake of the air, and the intake valve for exclusive use of the air, the opening / closing engine of the intake port, the turbocharger, the supercharger, etc.
Install the supercharger.

[0010]

The two-cycle gasoline engine and the two-cycle diesel engine configured as described above are opened and closed by a piston valve and a rotary valve, and opened in a scavenging process,
It is easy to increase the compression ratio due to the fact that it is closed in the compression process and has an empty space.

Also, in the case of multi-cylinder, the stagnant time of air-fuel mixture and air compressed into an empty space due to connecting empty spaces to one is determined by the same engine explosion speed. If so, it can be shortened, and depending on the number of cylinders and the rotation angle of the crank shaft that opens and closes an empty space, it opens in the scavenging process and closes in the compression process. The air-fuel mixture does not compress the air-fuel mixture or the air alone, and goes in and out.

As a measure against excessive opening of the valve and the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. A higher compression ratio can be obtained by providing an intake valve and intake port exclusively for air that are opened and closed in the exhaust process, the scavenging process, or the compression process.

In addition, due to the use of a supercharger such as a turbocharger or a supercharger during the air-fuel mixture intake process or air intake process of the above engine, if the same displacement and same explosion speed are used, You can get more power and torque.

Further, as a measure against excessive opening of the valve or the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. Air is pressurized due to the use of a turbocharger, such as a turbocharger or supercharger, for the intake valve and intake port for air that is opened, closed in the exhaust process, scavenging process, or compressed process. Backflow of exhaust gas is easy to prevent,
In addition, the opening and closing timing can be easily adjusted, and a large amount of exhaust gas can be removed.

[0015]

The process of an engine that uses a rotary valve in a two-cycle gasoline engine to obtain a high compression ratio and the process of an engine that uses a piston valve in a two-cycle diesel engine to obtain a high compression ratio are as follows: Although not drawn, if you change the piston valve to a rotary valve and the rotary valve to a piston valve, you can draw a diagram of each process.

In the embodiment shown in FIGS. 23 and 24, the method of dealing with the valve (piston valve) and the air port (rotary valve) which is opened in the scavenging step and closed in the compression step is taken along the line AA, FIG. 24 is a view assuming that the view is taken from the direction of the cross section BB, and FIG. 23 illustrates a method of coping with an engine that obtains a high compression ratio by using a piston valve in a two-cylinder two-cycle gasoline engine, Due to the fact that the empty spaces attached to each cylinder, which are opened in the scavenging process, closed in the compression process, are connected to one, if the explosion speed of the same engine is the ), To reduce the time it takes to temporarily stall in an empty space,

(The rotary valve in FIG. 24 is extended from the end cylinder to the end cylinder and is sealed. Also, when a piston valve and a rotary valve are used in a 2-cycle gasoline engine, Regardless of the engine type, the method of coping with an engine that obtains a high compression ratio by using a piston valve or a rotary valve is to open the cylinder in the scavenging process and then close it after entering the compression process.・ If shaft rotation angle × number of cylinders ≧ 360 °, open in scavenging process, close in compression process,
You can draw a diagram showing that you only need to connect the valve and the air port to one, or you can seal the rotary valve, depending on the type of rotary valve and engine type. )

[0021]

Since the present invention is configured as described above, it has the following effects.

A two-cycle gasoline engine, a two-cycle diesel engine, a piston valve and a rotary valve are used to open in a scavenging process and close in a compression process (an air-fuel mixture or air is temporarily stagnant). Due to the installation of the
A high compression ratio can be obtained, and as a result, the combustion efficiency can be improved, and in the case of multiple cylinders (two or more cylinders), due to the fact that one empty space is connected to one, If the same explosive rotation speed, it is possible to shorten the time that air stagnates, or depending on the number of cylinders, open and close with a piston valve, a rotary valve, open with a scavenging process, and close with a compression process. It is also possible to just connect the valve (piston valve) and the air port (rotary valve) together. (In an engine that uses a rotary valve to obtain a high compression ratio, such as a 2-cycle gasoline engine and a 2-cycle diesel engine, the rotary valve may be sealed depending on the type of the rotary valve and the engine.)

Further, a valve which is opened and closed by a piston valve and a rotary valve, opened by a scavenging process and closed by a compression process,
As a countermeasure when the air opening is opened too much in the compression process, it is opened in the expansion process and closed in the exhaust process, the scavenging process, or the compression process.
A higher compression ratio can be obtained, and the air is pressurized due to the turbocharger, supercharger, or other supercharger attached to the air intake valve and intake port for the air. It is easy to take, and much exhaust gas can be removed.

A turbocharger, supercharger, or other supercharger is used in an engine that obtains a high compression ratio by using a piston valve or a rotary valve in the above-described two-cycle gasoline engine or two-cycle diesel engine. If they are used for intake of air-fuel mixture and intake of air, respectively, it is possible to obtain larger power and torque at the same rotation speed and the same displacement.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine for obtaining a high compression ratio by using a piston valve and a rotary valve in a two-cycle gasoline engine and a two-cycle diesel engine, and an auxiliary device for the engine.

[0002]

2. Description of the Related Art A conventional two-stroke gasoline engine,
In a 2-cycle diesel engine, scavenging, compression, combustion, and exhaust were performed in two strokes (two steps).

[0003]

In the conventional 2-cycle gasoline engine and 2-cycle diesel engine, a 4-cycle engine (gasoline and diesel),
Compared with a 6-cycle engine (gasoline and diesel, 1990 Patent Application No. 417964), there were problems that the compression ratio was low and the combustion efficiency was poor.

The present invention is a two-stroke gasoline engine,
The purpose of the engine is to obtain a high compression ratio by using a piston valve and a rotary valve in a two-cycle diesel engine. Further, when the engine is used, the same displacement can be obtained depending on the explosion speed of the engine. The purpose is to obtain more power and torque at the same rotation speed.

[0005]

In order to achieve the above object, a piston valve and a rotary valve are used in the two-cycle gasoline engine and the two-cycle diesel engine of the present invention to open in the scavenging process and to open in the compression process. Close, valve (piston valve), mouth (rotary valve)
Is provided.

[0006] There is nothing in the valve and the air port that is opened and closed by the piston valve and the rotary valve (air mixture or
Place where the air temporarily stagnates).

In addition, when there are multiple cylinders, an empty space is connected to one space.

Then, as a countermeasure against closing the valve in the compression process and opening the air port too much, during the expansion process, the air-fuel mixture or air expands too much, and conversely opens before it becomes a resistance to rotation. An air intake valve and an intake port dedicated to air, which are closed in the exhaust process, the scavenging process, or the compression process, are provided.

In addition, the intake of the air-fuel mixture, the intake of the air, and the intake valve for exclusive use of the air, the opening / closing engine of the intake port, the turbocharger, the supercharger, etc.
Install the supercharger.

[0010]

The two-cycle gasoline engine and the two-cycle diesel engine configured as described above are opened and closed by a piston valve and a rotary valve, and opened in a scavenging process,
It is easy to increase the compression ratio due to the fact that it is closed in the compression process and has an empty space.

Also, in the case of multi-cylinder, the stagnant time of air-fuel mixture and air compressed into an empty space due to connecting empty spaces to one is determined by the same engine explosion speed. If so, it can be shortened, and depending on the number of cylinders and the rotation angle of the crank shaft that opens and closes an empty space, it opens in the scavenging process and closes in the compression process. The air-fuel mixture does not compress the air-fuel mixture or the air alone, and goes in and out.

As a measure against excessive opening of the valve and the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. A higher compression ratio can be obtained by providing an intake valve and intake port exclusively for air that are opened and closed in the exhaust process, the scavenging process, or the compression process.

In addition, due to the use of a supercharger such as a turbocharger or a supercharger during the air-fuel mixture intake process or air intake process of the above engine, if the same displacement and same explosion speed are used, You can get more power and torque.

Further, as a measure against excessive opening of the valve or the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. Air is pressurized due to the use of a turbocharger, such as a turbocharger or supercharger, for the intake valve and intake port for air that is opened, closed in the exhaust process, scavenging process, or compressed process. Backflow of exhaust gas is easy to prevent,
In addition, the opening and closing timing can be easily adjusted, and a large amount of exhaust gas can be removed.

Since the present invention is configured as described above, it has the following effects.

A two-cycle gasoline engine, a two-cycle diesel engine, a piston valve and a rotary valve are used to open in a scavenging process and close in a compression process (an air-fuel mixture or air is temporarily stagnant). Due to the installation of the
A high compression ratio can be obtained, and as a result, the combustion efficiency can be improved, and in the case of multiple cylinders (two or more cylinders), due to the fact that one empty space is connected to one, If the same explosive rotation speed, it is possible to shorten the time that air stagnates, or depending on the number of cylinders, open and close with a piston valve, a rotary valve, open with a scavenging process, and close with a compression process. It is also possible to just connect the valve (piston valve) and the air port (rotary valve) together. (In an engine that uses a rotary valve to obtain a high compression ratio, such as a 2-cycle gasoline engine and a 2-cycle diesel engine, the rotary valve may be sealed depending on the type of the rotary valve and the engine.)

Further, a valve which is opened and closed by a piston valve and a rotary valve, opened by a scavenging process and closed by a compression process,
As a countermeasure when the air opening is opened too much in the compression process, it is opened in the expansion process and closed in the exhaust process, the scavenging process, or the compression process.
A higher compression ratio can be obtained, and the air is pressurized due to the turbocharger, supercharger, or other supercharger attached to the air intake valve and intake port for the air. It is easy to take, and much exhaust gas can be removed.

A turbocharger, supercharger, or other supercharger is used in an engine that obtains a high compression ratio by using a piston valve or a rotary valve in the above-described two-cycle gasoline engine or two-cycle diesel engine. If they are used for intake of air-fuel mixture and intake of air, respectively, it is possible to obtain larger power and torque at the same rotation speed and the same displacement.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine for obtaining a high compression ratio by using a piston valve and a rotary valve in a two-cycle gasoline engine and a two-cycle diesel engine, and an auxiliary device for the engine.

[0002]

2. Description of the Related Art A conventional two-stroke gasoline engine,
In a 2-cycle diesel engine, scavenging, compression, combustion, and exhaust were performed in two strokes (two steps).

[0003]

In the conventional 2-cycle gasoline engine and 2-cycle diesel engine, a 4-cycle engine (gasoline and diesel),
Compared with a 6-cycle engine (gasoline and diesel, 1990 Patent Application No. 417964), there were problems that the compression ratio was low and the combustion efficiency was poor.

The present invention is a two-stroke gasoline engine,
The purpose of the engine is to obtain a high compression ratio by using a piston valve and a rotary valve in a two-cycle diesel engine. Further, when the engine is used, the same displacement can be obtained depending on the explosion speed of the engine. The purpose is to obtain more power and torque at the same rotation speed.

[0005]

In order to achieve the above object, a piston valve and a rotary valve are used in the two-cycle gasoline engine and the two-cycle diesel engine of the present invention to open in the scavenging process and to open in the compression process. Close, valve (piston valve), mouth (rotary valve)
Is provided.

[0006] There is nothing in the valve and the air port that is opened and closed by the piston valve and the rotary valve (air mixture or
Place where the air temporarily stagnates).

In addition, when there are multiple cylinders, an empty space is connected to one space.

Then, as a countermeasure against closing the valve in the compression process and opening the air port too much, during the expansion process, the air-fuel mixture or air expands too much, and conversely opens before it becomes a resistance to rotation. An air intake valve and an intake port dedicated to air, which are closed in the exhaust process, the scavenging process, or the compression process, are provided.

In addition, the intake of the air-fuel mixture, the intake of the air, and the intake valve for exclusive use of the air, the opening / closing engine of the intake port, the turbocharger, the supercharger, etc.
Install the supercharger.

[0010]

The two-cycle gasoline engine and the two-cycle diesel engine configured as described above are opened and closed by a piston valve and a rotary valve, and opened in a scavenging process,
It is easy to increase the compression ratio due to the fact that it is closed in the compression process and has an empty space.

Also, in the case of multi-cylinder, the stagnant time of air-fuel mixture and air compressed into an empty space due to connecting empty spaces to one is determined by the same engine explosion speed. If so, it can be shortened, and depending on the number of cylinders and the rotation angle of the crank shaft that opens and closes an empty space, it opens in the scavenging process and closes in the compression process. The air-fuel mixture does not compress the air-fuel mixture or the air alone, and goes in and out.

As a measure against excessive opening of the valve and the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. A higher compression ratio can be obtained by providing an intake valve and intake port exclusively for air that are opened and closed in the exhaust process, the scavenging process, or the compression process.

In addition, due to the use of a supercharger such as a turbocharger or a supercharger during the air-fuel mixture intake process or air intake process of the above engine, if the same displacement and same explosion speed are used, You can get more power and torque.

Further, as a measure against excessive opening of the valve and the air port from the empty space, during the expansion process, the air-fuel mixture or the air expands excessively and, on the contrary, becomes resistance to rotation. Air is pressurized due to the use of a supercharger such as a turbocharger or supercharger for the air intake valve and intake port that are opened to the air and closed in the exhaust process, scavenging process, or compression process. , Easy to prevent backflow of exhaust gas,
In addition, the opening and closing timing can be easily adjusted, and a large amount of exhaust gas can be removed.

[0015]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine for obtaining a high compression ratio by using a piston valve and a rotary valve in a two-cycle gasoline engine and a two-cycle diesel engine, and an auxiliary device for the engine.

[0002]

2. Description of the Related Art A conventional two-stroke gasoline engine,
In a 2-cycle diesel engine, scavenging, compression, combustion, and exhaust were performed in two strokes (two steps).

[0003]

In the conventional 2-cycle gasoline engine and 2-cycle diesel engine, a 4-cycle engine (gasoline and diesel),
Compared with a 6-cycle engine (gasoline and diesel, 1990 Patent Application No. 417964), there were problems that the compression ratio was low and the combustion efficiency was poor.

The present invention is a two-stroke gasoline engine,
The purpose of the engine is to obtain a high compression ratio by using a piston valve and a rotary valve in a two-cycle diesel engine. Further, when the engine is used, the same displacement can be obtained depending on the explosion speed of the engine. The purpose is to obtain more power and torque at the same rotation speed.

[0005]

In order to achieve the above object, a piston valve and a rotary valve are used in the two-cycle gasoline engine and the two-cycle diesel engine of the present invention to open in the scavenging process and to open in the compression process. Close, valve (piston valve), mouth (rotary valve)
Is provided.

[0006] There is nothing in the valve and the air port that is opened and closed by the piston valve and the rotary valve (air mixture or
Place where the air temporarily stagnates).

In addition, when there are multiple cylinders, an empty space is connected to one space.

Then, as a countermeasure against closing the valve in the compression process and opening the air port too much, during the expansion process, the air-fuel mixture or air expands too much, and conversely opens before it becomes a resistance to rotation. An air intake valve and an intake port dedicated to air, which are closed in the exhaust process, the scavenging process, or the compression process, are provided.

In addition, the intake of the air-fuel mixture, the intake of the air, and the intake valve for exclusive use of the air, the opening / closing engine of the intake port, the turbocharger, the supercharger, etc.
Install the supercharger.

[0010]

The two-cycle gasoline engine and the two-cycle diesel engine configured as described above are opened and closed by a piston valve and a rotary valve, and opened in a scavenging process,
It is easy to increase the compression ratio due to the fact that it is closed in the compression process and has an empty space.

Also, in the case of multi-cylinder, the stagnant time of air-fuel mixture and air compressed into an empty space due to connecting empty spaces to one is determined by the same engine explosion speed. If so, it can be shortened, and depending on the number of cylinders and the rotation angle of the crank shaft that opens and closes an empty space, it opens in the scavenging process and closes in the compression process. The air-fuel mixture does not compress the air-fuel mixture or the air alone, and goes in and out.

As a measure against excessive opening of the valve and the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. A higher compression ratio can be obtained by providing an intake valve and intake port exclusively for air that are opened and closed in the exhaust process, the scavenging process, or the compression process.

In addition, due to the use of a supercharger such as a turbocharger or a supercharger during the air-fuel mixture intake process or air intake process of the above engine, if the same displacement and same explosion speed are used, You can get more power and torque.

Further, as a measure against excessive opening of the valve and the air port from the empty space, during the expansion process, the air-fuel mixture or the air expands excessively and, on the contrary, becomes resistance to rotation. Air is pressurized due to the use of a supercharger such as a turbocharger or supercharger for the air intake valve and intake port that are opened to the air and closed in the exhaust process, scavenging process, or compression process. , Easy to prevent backflow of exhaust gas,
In addition, the opening and closing timing can be easily adjusted, and a large amount of exhaust gas can be removed.

A high compression ratio can be obtained, and as a result, the combustion efficiency can be improved, and in the case of multiple cylinders (two or more cylinders), due to the fact that one empty space is connected to one, If the same explosive rotation speed, it is possible to shorten the time that air stagnates, or depending on the number of cylinders, open and close with a piston valve, a rotary valve, open with a scavenging process, and close with a compression process. It is also possible to just connect the valve (piston valve) and the air port (rotary valve) together.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine for obtaining a high compression ratio by using a piston valve and a rotary valve in a two-cycle gasoline engine and a two-cycle diesel engine, and an auxiliary device for the engine.

[0002]

2. Description of the Related Art A conventional two-stroke gasoline engine,
In a 2-cycle diesel engine, scavenging, compression, combustion, and exhaust were performed in two strokes (two steps).

[0003]

In the conventional 2-cycle gasoline engine and 2-cycle diesel engine, a 4-cycle engine (gasoline and diesel),
Compared with a 6-cycle engine (gasoline and diesel, 1990 Patent Application No. 417964), there were problems that the compression ratio was low and the combustion efficiency was poor.

The present invention is a two-stroke gasoline engine,
The purpose of the engine is to obtain a high compression ratio by using a piston valve and a rotary valve in a two-cycle diesel engine. Further, when the engine is used, the same displacement can be obtained depending on the explosion speed of the engine. The purpose is to obtain more power and torque at the same rotation speed.

[0005]

In order to achieve the above object, when a piston valve and a rotary valve are used in a two-cycle gasoline engine and a two-cycle diesel engine of the present invention, they are opened and compressed in a scavenging process. Provide a valve (piston valve) and air port (rotary valve) that are closed during the process.

[0006] There is nothing in the valve and the air port that is opened and closed by the piston valve and the rotary valve (air mixture or
Place where the air temporarily stagnates).

In addition, when there are multiple cylinders, an empty space is connected to one space.

Then, as a countermeasure against closing the valve in the compression process and opening the air port too much, during the expansion process, the air-fuel mixture or air expands too much, and conversely opens before it becomes a resistance to rotation. An air intake valve and an intake port dedicated to air, which are closed in the exhaust process, the scavenging process, or the compression process, are provided.

In addition, the intake of the air-fuel mixture, the intake of the air, and the intake valve for exclusive use of the air, the opening / closing engine of the intake port, the turbocharger, the supercharger, etc.
Install the supercharger.

[0010]

The two-cycle gasoline engine and the two-cycle diesel engine configured as described above are opened in the scavenging process of opening and closing with the piston valve and the rotary valve,
It is easy to increase the compression ratio due to the fact that it is closed in the compression process and has an empty space.

Also, in the case of multi-cylinder, the stagnant time of air-fuel mixture and air compressed into an empty space due to connecting empty spaces to one is determined by the same engine explosion speed. If so, it can be shortened, and depending on the number of cylinders and the rotation angle of the crank shaft that opens and closes an empty space, it opens in the scavenging process and closes in the compression process. The air-fuel mixture does not compress the air-fuel mixture or the air alone, and goes in and out.

As a measure against excessive opening of the valve and the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. A higher compression ratio can be obtained by providing an intake valve and intake port exclusively for air that are opened and closed in the exhaust process, the scavenging process, or the compression process.

In addition, due to the use of a supercharger such as a turbocharger or a supercharger during the air-fuel mixture intake process or air intake process of the above engine, if the same displacement and same explosion speed are used, You can get more power and torque.

Further, as a measure against excessive opening of the valve and the air port from the empty space, during the expansion process, the air-fuel mixture or the air expands excessively and, on the contrary, becomes resistance to rotation. Air is pressurized due to the use of a supercharger such as a turbocharger or supercharger for the air intake valve and intake port that are opened to the air and closed in the exhaust process, scavenging process, or compression process. , Easy to prevent backflow of exhaust gas,
In addition, the opening and closing timing can be easily adjusted, and a large amount of exhaust gas can be removed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine for obtaining a high compression ratio by using a piston valve and a rotary valve in a two-cycle gasoline engine and a two-cycle diesel engine, and an auxiliary device for the engine.

[0002]

2. Description of the Related Art A conventional two-stroke gasoline engine,
In a 2-cycle diesel engine, scavenging, compression, combustion, and exhaust were performed in two strokes (two steps).

[0003]

In the conventional 2-cycle gasoline engine and 2-cycle diesel engine, a 4-cycle engine (gasoline and diesel),
There is a problem that the compression ratio is lower than that of a 6-cycle engine (gasoline and diesel, 1990 Patent Application No. 417964).

The present invention is a two-stroke gasoline engine,
The purpose of the engine is to obtain a high compression ratio by using a piston valve and a rotary valve in a two-cycle diesel engine. Further, when the engine is used, the same displacement can be obtained depending on the explosion speed of the engine. The purpose is to obtain more power and torque at the same rotation speed.

[0005]

In order to achieve the above object, when a piston valve and a rotary valve are used in a two-cycle gasoline engine and a two-cycle diesel engine of the present invention, they are opened and compressed in a scavenging process. Provide a valve (piston valve) and air port (rotary valve) that are closed during the process.

[0006] There is nothing in the valve and the air port that is opened and closed by the piston valve and the rotary valve (air mixture or
Place where the air temporarily stagnates).

In addition, when there are multiple cylinders, an empty space is connected to one space.

Then, as a countermeasure against closing the valve in the compression process and opening the air port too much, during the expansion process, the air-fuel mixture or air expands too much, and conversely opens before it becomes a resistance to rotation. An air intake valve and an intake port dedicated to air, which are closed in the exhaust process, the scavenging process, or the compression process, are provided.

In addition, the intake of the air-fuel mixture, the intake of the air, and the intake valve for exclusive use of the air, the opening / closing engine of the intake port, the turbocharger, the supercharger, etc.
Install the supercharger.

[0010]

The two-cycle gasoline engine and the two-cycle diesel engine configured as described above are opened in the scavenging process of opening and closing with the piston valve and the rotary valve,
It is easy to increase the compression ratio due to the fact that it is closed in the compression process and has an empty space.

Also, in the case of multi-cylinder, the stagnant time of air-fuel mixture and air compressed into an empty space due to connecting empty spaces to one is determined by the same engine explosion speed. If so, it can be shortened, and depending on the number of cylinders and the rotation angle of the crank shaft that opens and closes an empty space, it opens in the scavenging process and closes in the compression process. The air-fuel mixture does not compress the air-fuel mixture or the air alone, and goes in and out.

As a measure against excessive opening of the valve and the air outlet from the empty space, during the expansion process, the air-fuel mixture or air expands excessively and, on the contrary, becomes resistance to rotation. A higher compression ratio can be obtained by providing an intake valve and intake port exclusively for air that are opened and closed in the exhaust process, the scavenging process, or the compression process.

In addition, due to the use of a supercharger such as a turbocharger or a supercharger during the air-fuel mixture intake process or air intake process of the above engine, if the same displacement and same explosion speed are used, You can get more power and torque.

Further, as a measure against excessive opening of the valve and the air port from the empty space, during the expansion process, the air-fuel mixture or the air expands excessively and, on the contrary, becomes resistance to rotation. Air is pressurized due to the use of a supercharger such as a turbocharger or supercharger for the air intake valve and intake port that are opened to the air and closed in the exhaust process, scavenging process, or compression process. , Easy to prevent backflow of exhaust gas,
In addition, the opening and closing timing can be easily adjusted, and a large amount of exhaust gas can be removed.

[0021]

Since the present invention is configured as described above, it has the following effects.

A two-cycle gasoline engine, a two-cycle diesel engine, a piston valve and a rotary valve are used to open in a scavenging process and close in a compression process (an air-fuel mixture or air is temporarily stagnant). Due to the installation of the
A high compression ratio can be obtained, and as a result, the combustion efficiency can be improved, and in the case of multiple cylinders (two or more cylinders), due to the fact that one empty space is connected to one, If the same explosive rotation speed, it is possible to shorten the time that air stagnates, or depending on the number of cylinders, open and close with a piston valve, a rotary valve, open with a scavenging process, and close with a compression process. It is also possible to just connect the valve (piston valve) and the air port (rotary valve) together. (In an engine that uses a rotary valve to obtain a high compression ratio, such as a 2-cycle gasoline engine or a 2-cycle diesel engine, the rotary valve may be hermetically sealed depending on the rotary valve type and the engine type. Exclude from the cylinder.))

Further, a valve which is opened and closed by a piston valve and a rotary valve, opened by a scavenging process and closed by a compression process,
As a countermeasure when the air opening is opened too much in the compression process, it is opened in the expansion process and closed in the exhaust process, the scavenging process, or the compression process.
A higher compression ratio can be obtained, and the air is pressurized due to the turbocharger, supercharger, or other supercharger attached to the air intake valve and intake port for the air. It is easy to take, and much exhaust gas can be removed.

A turbocharger, supercharger, or other supercharger is used in an engine that obtains a high compression ratio by using a piston valve or a rotary valve in the above-described two-cycle gasoline engine or two-cycle diesel engine. If they are used for intake of air-fuel mixture and intake of air, respectively, it is possible to obtain larger power and torque at the same rotation speed and the same displacement.
