Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine for converting the energy of explosive combustion of fuel directly into circular motion.

[0002]

2. Description of the Related Art In a conventional reciprocating engine, an airtight chamber is formed by a cylinder and a piston, the piston is moved by the energy of explosive combustion, and the movement of the piston moving up and down via a crankshaft is changed to a circular motion. The crankshaft rotates 180 degrees while the piston reaches the bottom dead center from the top dead center. That is, the energy of the explosion combustion is received only 180 degrees. The movement of the piston from bottom dead center to top dead center is against inertia and consumes energy for it. In order to obtain a large rotating force, that is, a large moment, the area receiving the energy of the piston must be increased, and the turning radius of the crankshaft must be increased.However, the connecting rod becomes longer, and the displacement increases. As a result, the fuel used increases. Enlarging the engine in a limited space cannot be expected much.

[0003]

SUMMARY OF THE INVENTION The up and down movement of a piston is eliminated to reduce energy loss. Reduce fuel consumption during idling. Reduce engine size.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems by an engine that directly converts the energy of explosive combustion into a circular rotary motion.

[0005] The entire engine is sealed by an outer box 12 and a lid 17. Contact points with the outside are the rotating shaft 21 for transmitting the rotation of the engine to the outside and the three injection ports 3 and 7. The rotating shaft 21 is kept airtight by a rotating bearing 20. The injection ports 3 and 7 are shut off by an injection shut-off device to be described later, except at the time of injection of the compressed gas mixture, so that airtightness is maintained. The lid 17 is in close contact with the rotary valve 1, the rotary valve receiver 13, and the rotary valve storage cylinder 15 to maintain airtightness. As shown in FIG. 4, the components are in close contact with each other. The rotary valve storage cylinder 15 and the rotary valve receiver 13 are in contact with each other while rotating, thereby maintaining airtightness. One end of the rotary valve 1 is housed in a rotary valve housing 11 and the hinged male 9 at the other end is housed in a hinged female 10 to maintain airtightness. The first compressed mixed gas closed chamber and the second compressed mixed gas closed chamber become a part of the combustion expansion chamber in the explosion combustion step, but become airtight chambers in the injection step. Combustion expansion chamber 6
It is an airtight room where airtightness is maintained. The exhaust chamber 14 is also
It is an airtight room that is kept airtight except for the exhaust port.

The rotary valve 1, the rotary valve storage cylinder 15, and the rotary valve receiver 13 rotate counterclockwise in conjunction with each other. The rotary valve storage cylinder 15 rotates about a rotary shaft 16 and is inscribed in a rotary valve receiver 13 that rotates about a rotary shaft 21. Rotary valve 1
Rotates about the rotary shaft 16, and its trajectory is determined by the rotation of the rotary valve bearing 13 and the rotary valve storage cylinder 15. Adjustment of the length of the rotary valve 1 from the perigee to the apogee or from the apogee to the perigee on the track with respect to the rotary shaft 16 is performed by the amount of the rotary valve 1 stored in the rotary valve storage 11. Although the angle of the rotary valve 1 with respect to the rotary valve receiver 13 changes with rotation, the hinge male 9 and the female hinge 10 adapt to the change.

[0007] Two gas compression devices are installed outside the engine, and each of the injection ports 3, 7 is provided through two injection blocking devices.
Compressed gas mixture is injected into. The basic concept of the gas compression device is exactly the same as that of the engine body. That is, the rotary valve 28, the rotary valve storage cylinder 24, the rotary valve receiver 23, and the outer case 2
2 and the basic structure is the same. The difference is that the combustion expansion chamber 6 of the engine becomes the suction chamber 25 and the exhaust chamber 14
To the compression chamber 30, the absence of the combustion gas inlet 5 in the gas compressor, and the inlets 3, 7 of the main engine.
Is that the position of the suction port 33 is different.

In the injection blocking device, the injection blocking fan-shaped plate has a rotating shaft 3.
7, the inlet 3 is closed by blocking the inlet and outlet.
7 is to be blocked.

[0009] An injection cutoff device is connected between the engine body and the gas compression device. The outlet and the inlets 3 and 7 are connected as short as possible to minimize the intrusion of the explosive combustion gas into the outlet and the spread of fire during the explosion combustion.

[0010] The rotary valve 28 and the injection blocking fan plate rotate in conjunction with each other.

[0011]

When the rotary valve receiver 13 rotates and the first compressed mixed gas closed chamber and the second compressed mixed gas closed chamber are in an airtight state, the compressed mixed gas is injected from the injection ports 3 and 7. Immediately before the rotating combustion gas inlet 5 reaches the first compressed mixed gas closed chamber, a high voltage is applied to the spark plug to blow off the sparks, causing explosive combustion in the first compressed mixed gas closed chamber. The explosive combustion spreads to the combustion expansion chamber 6 at a stretch. When the rotary valve 1 receives the energy of the explosive combustion and rotates and the combustion gas inlet 5 reaches the second mixed gas closed chamber, the high temperature gas currently in the explosive combustion becomes the compressed mixed gas in the second mixed gas closed chamber. It ignites and causes a second explosion combustion to spread to the combustion expansion chamber, and the energy of the rotary valve 1 further increases its rotation. During idling, only the compressed air containing no fuel is injected into the second compressed mixed gas closed chamber.

When the rotary valve 1 is completely housed in the rotary valve housing cylinder, that is, when the hinge male 9 is at the top, the angle is 90 degrees. The process from when the rotary valve 1 rotates 360 degrees and returns to the original position is called an explosive combustion process.
This is the process of converting the energy of explosive combustion into circular motion. The second 360-degree rotation is called an injection step. This is the step in which the compressed mixed gas is injected into the first and second mixed gas sealed chambers. After the injection process, the process returns to the explosive combustion process. The exhaust port is always open. Therefore, the exhaust gas is exhausted by its own pressure and also by the rotation of the rotary valve 1. The evacuation is performed regardless of the above two steps. The exhaust gas in the injection step is also used to exhaust the combustion gas remaining in the first and second compressed mixed gas closed chambers.

In the above two steps, the rotary valve 28 of the gas compressor is
And the rotation of the injection blocking fan is adjusted. The explosive combustion process must shut off the injection of the compressed gas mixture,
In the injection step, injection must be performed. The injection block fan rotates 180 degrees while the rotary valve 1 of the engine body rotates 360 degrees. That is, the injection blocking fan plate makes one rotation while the rotary valve 1 makes two rotations. Similarly, the rotary valve 28 of the gas compression device also rotates 180 degrees while the rotary valve 1 rotates 360 degrees. Thereby, it can be adapted to the above two steps.

The first and second mixed gas sealed chambers are dome-shaped, but the ceiling is made as low as possible. In other words, instead of a bowl type, make a dish shape and widen the skirt. As a result, the time during which the combustion gas inlet 5 is in contact with the first and second compressed mixed gas sealed chambers becomes longer, and the time during which the energy of explosive combustion is received becomes longer. Therefore, the rotation efficiency is improved. Exhaust also becomes easier.

The capacity of the rotary valve receiving cylinder 15 minus the volume of the rotary valve housing cylinder 15 when the rotary valve receiver 13 is regarded as a cylinder with a bottom ignoring the combustion gas inlet 5 in the rotary valve receiver 13 is the displacement of the engine of the present invention. Think. If the displacement is increased, the rotational force can be increased. If the rotary valve storage cylinder 15 is made smaller, the displacement can be increased. Rotary valve storage 11
Can be reduced to the limit of the capacity of storing the rotary valve 1. That is, the diameter of the rotary valve storage cylinder 15 can be reduced until it becomes closer to the radius of the rotary valve receiver 13. Therefore, the displacement can be increased to nearly 75% of the capacity of the rotary valve bearing 13.

In order to increase the rotational force when the displacement is constant, the rotational radius of the rotary valve receiver 13 is increased to increase the moment, that is, the rotational force. Therefore, the rotary valve 1 also becomes long. The energy that the rotary valve 1 receives in explosive combustion is the same in unit area, but the energy given to the rotation of the rotary valve receiver 13 differs depending on the location where the energy is received. That is, the location on the surface of the rotary valve 1 that receives the energy is larger as it is closer to the rotary valve receiver 13, and weaker as it is closer to the rotary shaft 16. Therefore, the radius of the rotary valve storage cylinder 15 is increased so as not to receive explosive combustion energy near the rotary shaft 16 where efficiency is poor. That is, the displacement or capacity is used to increase the radius of rotation of the rotary valve receiver 13 and the length and width of the rotary valve 1. The rotary valve receiver 13 is designed so that the rotational force is maximized at a predetermined displacement.
, The radius of the rotary valve storage cylinder 15, the length and width of the rotary valve 1 are set. Setting the width of the rotary valve 1 means setting the widths of the rotary valve receiver 13 and the rotary valve storage cylinder 15. The width referred to here means the left and right lengths in FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings for the embodiment, FIG. 1 shows that after the explosion and combustion in the first compressed gas mixed chamber, the rotary valve is rotated to bring the combustion gas inlet to the second mixed gas closed chamber and the second time. Explosive combustion has just begun. FIG. 2 shows the state after the lapse of time in FIG. 1, in which the rotary valve has rotated to 270 degrees. FIG. 3 shows a lid for sealing the engine shown in FIGS. FIG. 4 is a longitudinal sectional view when the lid of FIG. 3 is attached to FIG. It is used as an engine.

FIGS. 5 and 6 show a gas compression device which is used by rotating a rotary valve by obtaining a torque from the outside. In the case of liquid, it can be used as a pump.

FIG. 9 shows a diesel engine system. That is, the second compressed mixed gas closed chamber 8 is used as the compressed air closed chamber 53. Seal high-pressure air to high temperature. The fuel is injected at the same timing as the rotation of the combustion gas inlet to ignite from the gas under spontaneous combustion or explosive combustion to cause explosive combustion. Similarly, the compressed mixed gas sealed chamber 48 can be made diesel.

[0020]

According to the present invention, the following effects can be obtained by directly changing the energy of the explosive combustion of fuel into circular motion.

Energy loss due to the vertical movement of the piston can be prevented.

The first and second closed chambers for the compressed gas mixture are provided. The use of only the first closed chamber for the compressed gas mixture during idling improves fuel efficiency and reduces exhaust gas.

The first compressed mixed gas closed chamber can make the rotary valve 1 during idling, that is, a capacity capable of sealing the compressed mixed gas necessary for rotating the engine. The second compressed gas closed chamber can have a capacity capable of sealing the compressed mixed gas necessary for obtaining a rotational force suitable for the purpose of use of the engine.

By setting two gas compression devices outside the main body, the compression ratio of the mixed gas and the mixing ratio of the fuel in the first compressed mixed gas closed chamber and the second compressed mixed gas closed chamber can be set respectively. And fuel efficiency is improved.

Since the rotary valve 1 receives the energy of the explosive combustion from the first compressed mixed gas closed chamber to the exhaust port and rotates, its rotation angle is larger than 180 degrees of the reciprocating engine. In addition, at 270 degrees, which is the bottom dead center of the reciprocating engine, the rotary valve 1 is perpendicular to the rotary valve receiver 13, and the area of the rotary valve 1 that receives the energy of the explosive combustion is the largest, and the male male hinge 9 Since the length from the shaft to the rotating shaft 16 is the longest, the rotating valve bearing 13 can receive a large moment. Therefore, efficiency is high.

The engine of the present invention has a built-in portion corresponding to the cylinder, piston, connecting rod and crankshaft of the reciprocating engine, so that the engine body can be made smaller than the reciprocating engine.
