Description

The present invention relates to an engine that injects gas into water to accelerate the water flow, and uses that force to move a piston up and down.

In an automobile engine, pistons reciprocate inside cylinders, and this reciprocating motion is converted into rotational motion by the crankshaft and used as power.

To make the piston reciprocate, the following processes are repeated: an intake stroke in which fuel mixed with air is drawn into the cylinder; a compression stroke in which the piston rises and compresses the intake mixture; a combustion and expansion stroke in which the compressed mixture is ignited and burned by a spark from the spark plug, expanding and pushing the piston down; and an exhaust stroke in which an exhaust valve opens and exhaust gases are discharged as the piston rises again (Patent Document 1 below).

However, modern society is moving towards carbon neutrality, and there is a demand to reduce CO2 emissions from engines.

The present invention responds to these demands and aims to provide an engine that does not emit CO2.

The present invention is an engine that uses an accelerated flow of liquid to move a piston up and down, and comprises a container that stores liquid, a first piston that moves up and down in the liquid, a second piston that moves up and down in the liquid in a direction opposite to that of the first piston, a wire that connects the lower end of the first piston to the lower end of the second piston in the liquid, a crankshaft located outside the container and to which the upper ends of the first and second pistons are connected via a connecting rod, two cylinders that define the movement paths of the first and second pistons inside the container , and a gas injection pipe that injects gas from below into each of the cylinders to accelerate the liquid in the cylinders , and gas is injected alternately from the gas injection pipe into the two cylinders.

In addition, when one of the first and second pistons rises, the wire exerts a downward force on the other piston.

Therefore, in this engine, when gas is injected from the gas injection pipe into one of the cylinders, the gas accelerates the liquid in the cylinder, which pushes up one of the pistons, causing it to rise. Meanwhile, the other piston is pulled by the wire and falls. Both the rising piston and the falling piston exert a force on the engine's crankshaft to rotate it in the same direction, and the movement of these pistons causes the engine's crankshaft to rotate.

In the engine of the present invention, the cylinder is provided with a gas exhaust port for discharging gas, and this gas exhaust port opens when the piston is pushed up inside the cylinder.
This makes it possible to prevent the piston from being prevented from descending due to gas after it has risen.

In addition, compressed gas is supplied to the gas injection pipe from an oxygen gas cylinder, liquid nitrogen cylinder, air compressor, compressed gas tank, etc.

In addition, in the present invention, multiple engines as described above can be connected to the crankshaft to form a multi-cylinder engine.

The engine of the present invention can be adapted to be carbon neutral.

FIG. 4 is a diagram showing another embodiment of the engine of the present invention. FIG. 2 is a diagram showing a state in which the engine of FIG. 1 is mounted on an automobile. 1 in another state in which the engine of FIG. 1 is mounted on an automobile;

Hereinafter, the embodiment of the present invention will be described based on examples.
FIG. 1 shows an embodiment of an engine according to the present invention.
This engine has a water tank 10 that stores water 50, a first piston 21 that moves up and down in the water, a second piston 22 that moves up and down in the water in the opposite direction to the first piston 21, a wire 33 that connects the lower end of the first piston 21 with the lower end of the second piston 22, and a crankshaft 30 to which the upper ends of the first piston 21 and second piston 22 are connected via connecting rods 31, 32. The crankshaft 30 is disposed outside the water 50.

Furthermore, within the water tank 10, there are arranged a first cylinder 11 that defines the path of movement of the first piston 21, a second cylinder 12 that defines the path of movement of the second piston 22, a gas injection pipe 13 that injects gas into the first cylinder 11, a gas injection pipe 14 that injects gas into the second cylinder 12, a gas exhaust port 15 installed near the upper end of the first cylinder 11, and a gas exhaust port 16 installed near the upper end of the second cylinder 12.

Compressed gas is alternately supplied to the gas injection pipes 13 and 14 from an oxygen gas cylinder, a liquid nitrogen cylinder, an air compressor, a compressed gas tank, etc. When compressed gas is supplied, the gas injection pipe 13 injects the compressed gas into the first cylinder 11, and the gas injection pipe 14 injects the compressed gas into the second cylinder 12.

When the compressed gas is injected, the water 50 in the cylinders 11 and 12 into which it is injected is accelerated, and the water pressure of the accelerated water 50 pushes up the pistons 21 and 22 in the cylinders 11 and 12.

Figure 2(a) shows the movement of the main parts of the engine when compressed gas is supplied to the gas injection pipe 13. The piston 21 rises due to the water pressure of the accelerated water 50, and as a result, the piston 22 is pulled down by the wire 33. At this time, the connecting rod 31 connected to the piston 21 and the connecting rod 32 connected to the piston 22 exert a force that rotates the crankshaft 30 in the same direction, causing the crankshaft 30 to rotate.

Figure 2(b) shows the movement when compressed gas is supplied to the gas injection pipe 14. The piston 22 rises due to the water pressure of the accelerated water 50, and as a result, the piston 21 is pulled by the wire 33 and falls. At this time, a force acts on the crankshaft 30 from the connecting rods 31 and 32, rotating it in the same direction as in the state of Figure 2(a), so the crankshaft 30 continues to rotate in the same direction.

1, the cylinders 11, 12 are provided with gas exhaust ports 15, 16 near their upper ends for discharging the injected gas (air bubbles). The lower openings 151, 161 of the gas exhaust ports 15, 16 are positioned so that air bubbles can enter when the pistons 21, 22 rise to the state of the piston 21 in FIG.
Therefore, the air bubbles are discharged from the gas discharge ports 15 and 16 in a state where it is no longer necessary to push up the water 50 against the pistons 21 and 22 .
A plurality of obstacle plates are installed at the gas exhaust ports 15, 16 to reduce the upward force of the bubbles, and the bubbles entering from the openings 151, 161 of the gas exhaust ports 15, 16 lose momentum by contacting the obstacle plates and are quietly discharged from the upper ends of the gas exhaust ports 15, 16.

As shown in Figure 3, this engine can also be used as a multi-cylinder engine by connecting multiple cylinders to the crankshaft 30.

As shown in FIG. 1, an alternator (generator) 60 and a drive system are connected to the crankshaft 30 of the engine.
FIG. 4 shows an automobile equipped with an engine 80, an alternator 60 driven by the engine 80, a battery 82 that stores electricity generated by the alternator 60, and a compressor 81 that receives electricity from the battery 82 and supplies compressed air to the engine 80.

FIG. 5 also shows an engine 80, an alternator 60, a battery 82, and a gas tank 83 that supplies compressed gas to the engine 80, all of which are arranged in the automobile.
In this way, the engine of the present invention can power a vehicle without emitting CO2.

The engine of the present invention can be used not only in automobiles, but also as a power source in various industrial fields.
