Description of the Related Art In a conventional four-stroke engine or two-stroke engine, the air intake and compression strokes have been performed in the same cylinder as the cylinder that performs the explosion and expansion strokes. For this reason, the output was not always maximized when producing the optimum amount of compressed air for combustion.

Although it does not necessarily correspond to "a diameter and a stroke for producing a compression ratio and an air amount capable of complete combustion depending on the type of fuel", in the conventional technology, both explosion and expansion and air compression are performed by the same cylinder. This is one of the causes of incomplete combustion or energy loss. The present invention uses two cylinders, one for intake and compression, and the other for explosion and expansion and exhaust. As a result, it is possible to select a combination of cylinders that maximizes the force of explosion and expansion, and it is possible to supply the optimum air pressure and air amount for complete combustion.

In the case of performing explosive expansion and air compression, a so-called breathing phenomenon occurs because the process of compressing air by inertia is performed after the explosive expansion process ends. According to the present invention, two cylinders are used, one of which is dedicated to intake / compression and the other of which is dedicated to explosive expansion and exhaust, so that the phase can be adjusted and the expansive expansion stroke and the compression stroke timing are matched. be able to. Therefore, the engine can be smoothly rotated.

It only works for compression, and cylinder 2 only works for explosion / expansion and exhaust. The combination of the inner diameters of the cylinder 1 and the cylinder 2 and the piston stroke is a combination that "can maximize the power of explosion" and "give the amount of air and pressure necessary for complete combustion". The relationship between the strokes of the pistons in both cylinders is such that when the piston of the cylinder 2 is in the expansion and expansion stroke, the piston of the cylinder 1 is in the stroke of compressing air.

After the piston has entered the expansion process. At this time, water takes heat from the inside of the cylinder and changes from liquid to gas, increasing the volume all at once, so push the piston and turn the crank. Therefore, the engine of the present invention can take out a part of the heat, which has conventionally been the only way to discard it, as power.

Further, when the temperature of the cylinder 2 drops, the amount of water to be fed can be reduced or the feeding of water can be interrupted. The time when the atomized water is sent into the cylinder 2 is after the air-fuel mixture in the cylinder 2 explodes and the piston enters the expansion process.
