Description

Technical Field

[0001] The present invention relates to an engine that injects gas into water to accelerate the water flow and uses the force to move a piston up and down.

Background Art

[0002] In an engine mounted on an automobile, a piston reciprocates in a cylinder, and this reciprocating motion is converted into a rotational motion by a crankshaft and used as power.

[0003] Further, in order to cause the piston to reciprocate, an intake stroke in which fuel mixed with air is inhaled into the cylinder, a compression stroke in which the piston rises and compresses the inhaled air-fuel mixture, a combustion and expansion stroke in which the compressed air-fuel mixture is ignited and burned by a spark from a spark plug and expands to push down the piston, and an exhaust stroke in which the exhaust valve opens to discharge exhaust gas when the piston rises again are repeated (Patent Document 1 below).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in modern society, carbon neutrality is being pursued, and reduction of CO2 emissions from engines is required.

[0006] The present invention addresses such demands and aims to provide an engine that does not emit CO2.

Means for Solving the Problems

[0007] The present invention relates to an engine that moves a piston up and down by utilizing the flow of an accelerated liquid, and includes a container for storing the liquid, a first piston that moves up and down in the liquid, a second piston that moves up and down in the liquid in the opposite direction to the first piston, a wire that connects the lower end of the first piston and the lower end of the second piston in the liquid, a crankshaft disposed outside the container, to which the upper ends of the first piston and the second piston are connected via a connecting rod, two cylinders that define the movement paths of the first piston and the second piston, and a gas injection pipe that injects gas from below into each of the cylinders. Gas is alternately injected from the gas injection pipe into the two cylinders.

[0008] Further, when one of the first piston and the second piston rises, the wire exerts a force to lower the other.

[0009] Therefore, in this engine, when gas is injected from the gas injection pipe toward one of the cylinders, the gas accelerates the liquid in the cylinder, and the liquid pushes up the liquid, causing one of the piston pair to rise. Further, the other of the piston pair is pulled down by the wire. As the pistons move, the crankshaft of the engine rotates.

[0010] Further, in the engine of the present invention, a gas discharge port for discharging gas is provided in the cylinder, and this gas discharge port opens when the piston is pushed up in the cylinder. Therefore, it is possible to avoid a situation where the downward movement after the piston rises is hindered by the gas.

[0011] Further, compressed gas is supplied to the gas injection pipe from an oxygen gas cylinder, a liquid nitrogen cylinder, a compressor that compresses air, a compressed gas tank, or the like.

[0012] Further, in the present invention, a plurality of the above engines can be connected to the crankshaft to form a multi-cylinder engine.

Advantages of the Invention

[0013] The engine of the present invention can be adapted to carbon neutrality.

Modes for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described based on examples. FIG. 1 shows an embodiment of the engine of the present invention. This engine has a water tank 10 storing 50 of water, a first piston 21 moving up and down in the water, a second piston 22 moving up and down in the water in the opposite direction to the first piston 21, a wire 33 connecting the lower end of the first piston 21 and the lower end of the second piston 22, and a crankshaft 30 to which the upper ends of the first piston 21 and the second piston 22 are connected via connecting rods 31, 32. The crankshaft 30 is disposed outside the water 50.

[0016] Further, in the water tank 10, there are further disposed a first cylinder 11 defining the movement path of the first piston 21, a second cylinder 12 defining the movement path of the second piston 22, a gas injection pipe 13 injecting gas into the first cylinder 11, a gas injection pipe 14 injecting gas into the second cylinder 12, a gas discharge port 15 installed near the upper end of the first cylinder 11, and a gas discharge port 16 installed near the upper end of the second cylinder 12.

[0017] Compressed gas is alternately supplied to the gas injection pipes 13 and 14 from an oxygen gas cylinder, a liquid nitrogen cylinder, a compressor for compressing air, a compressed gas tank, etc. When the 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.

[0018] When the compressed gas is injected, the water 50 in the cylinders 11 and 12 into which it is injected is accelerated, and the pistons 21 and 22 in the cylinders 11 and 12 are pushed up by the water pressure of the accelerated water 50.

[0019] Figure 2(a) shows the movement of the main part of the engine when compressed gas is supplied to the gas injection pipe 13. The piston 21 rises under the water pressure of the accelerated water 50. Therefore, 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 act to rotate the crankshaft 30 in the same direction, so the crankshaft 30 rotates.

[0020] Also, Figure 2(b) shows the movement when compressed gas is supplied to the gas injection pipe 14. The piston 22 rises under the water pressure of the accelerated water 50. Therefore, the piston 21 is pulled down by the wire 33. At this time, a force to rotate the crankshaft 30 in the same direction as in the state of Figure 2(a) acts on the crankshaft 30 from the connecting rod 31 and the connecting rod 32, so the crankshaft 30 continues to rotate in the same direction.

[0021] Also, as shown in Figure 1, the cylinders 11 and 12 are provided with gas outlets 15 and 16 for discharging the injected gas (bubbles) near their upper ends. The lower openings 151 and 161 of the gas outlets 15 and 16 are set at positions such that bubbles can enter when the pistons 21 and 22 rise to the state of the piston 21 in Figure 1. Therefore, the bubbles are discharged from the gas discharge ports 15 and 16 in a state where it is not necessary to push up the water 50 against the pistons 21 and 22. A plurality of baffle plates for reducing the upward force of the bubbles are installed at the gas discharge ports 15 and 16. The bubbles that enter from the openings 151 and 161 of the gas discharge ports 15 and 16 lose their momentum by contacting the baffle plates and are gently discharged from the upper ends of the gas discharge ports 15 and 16.

[0022] As shown in FIG. 3, this engine can also be used as a multi-cylinder engine by being connected to a crankshaft 30 in plurality.

[0023] 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 a state in which an engine 80, an alternator 60 driven by the engine 80, a battery 82 for storing electricity generated by the alternator 60, and a compressor 81 that receives electricity supply from the battery 82 and supplies compressed air to the engine 80 are arranged in an automobile.

[0024] FIG. 5 shows a state in which an engine 80, an alternator 60, a battery 82, and a gas tank 83 for supplying compressed gas to the engine 80 are arranged in an automobile. Thus, the engine of the present invention can drive an automobile without discharging CO2.
