[Description of main parts of drawing]

Rotating piston engines have a pair of rotary pistons engaged in the timing gear shaft to rotate within the engine housing, with the protruding vanes attached (Fig. 3-7.8).

The rotating piston engine rotates 360 degrees and the A rotating piston and the B rotating piston blades are folded. At this time, the wings of each other should be precisely processed at the time of manufacture to avoid collision friction and should be manufactured with a certain gap between the wings and wings. If the engine is operated for a long time, the timing gear wear will progress, reducing the blade gap between the rotating piston blade and the blade friction. However, the friction generated is not friction with heavy loads, but friction with the piston blades and the blades. When friction occurs, the sealing effect of the engine cylinder becomes better. However, the timing gear metal should be made of metal with little abrasion. It is better if the metals of the pistons A and B are different from each other.

[Document 1] General principle of piston reciprocating internal combustion engine

[2] Vankel Rotary Institution, developed by Felix Wankel

The rotary piston engine of the present invention is an engine having more power and performance corresponding to a four-stroke two-cylinder reciprocating piston engine. In the piston reciprocating engine, the suction compression explosion exhaust process is performed every two revolutions of the crankshaft, and in the process, one explosion force is generated. When the piston rotates once, it gets twice the explosive power, so it can produce more performance than the reciprocating four-stroke four-cylinder and its output is simple. An important object of the present invention is to reduce friction in the engine structure as much as possible.

Hydrogen gas has the property of spontaneously exploding without the ignition of sparks when high pressure and high heat is generated in the air, and it is difficult to handle it as a gas that is extremely diffused in the air. There are a lot of problems in the structure of the engine has not been put to practical use so far.

Hydrogen gas is applied to the reciprocating piston engine. Since natural explosion occurs during the suction compression process, the crankshaft reverses and the components in the suction process are damaged. When the engine is operated by lowering the proper level, the output is weak and economical. The piston rotary engine of the present invention solves all the above problems, and the structure for generating power of the hydrogen mixed gas to a low pressure engine having a low compression process is simple and high efficiency. In rotary engines, a pair of rotary pistons generate power by rotating 360 ° in the engine housing. Unlike reciprocating engines, the rotary piston is designed to push the bi-directional pistons directly into the cylinder's initial explosion pressure. The first explosion pressure in a cylinder The highest pressure in the smallest volume of the cylinder The larger the volume of the cylinder, the lower the pressure in the cylinder. It is of utmost importance to obtain a strong torque using this high mechanical device. Can not exert a strong force (Fig. 4-1)

At the point where the piston cone crankshaft moves away from the vertical angle and the rotational angle increases and a strong force can be achieved, the pressure of the cylinder drops and begins to open the exhaust valve before the piston reaches the bottom dead center to reduce the pressure of the cylinder The engine drive power is quickly weakened by exhausting. However, in a piston rotary engine, the position of the cylinder does not start from the vertical as in the reciprocating engine. This leads to a strong turning force that pushes both pistons from the beginning of the explosion. In the Vankel engine, the explosive driving force acts as a right angle to the rotor, which acts as a disturbing force under the center of the explosion chamber. (Figure 4-2)

However, in the present invention, the force of the explosion acts in the engine rotational direction so that the efficiency of the power torque is high.

Looking at the structure of the reciprocating engine and the rotary piston engine, considering that both the reciprocating engine and the rotating piston engine have the same explosion pressure, the reciprocating engine moves up and down inside the cylinder without the central axis of the piston itself. The inner wall of the piston and the outer wall of the piston return to the top dead center of the expansion friction piston from the bottom dead center to the cylinder inner wall of the piston ring. The four-stroke reciprocating piston engine suffers from these problems and gains one explosion in the course of two repeated crankshafts. The actual effective driving force is said to be less than 25% of the initial explosive force. Rotary piston engines do not require reciprocating engine parts, so there is no energy loss.

Rotary piston advantages are as follows

1. It is a rotary piston without rebound resistance

2. Small number of parts

3 low friction loss

4. No suction exhaust valve

5 rotary piston oil cooling system

6 no fly wheel rotating piston + timing gear.

7. Low pressure is easy because the compression process is low pressure

8. The rotating piston shaft is bearing

9. 100% exhaust gas from cylinder

10. No organ vibration

Disadvantages of Rotating Piston Engines

1.Carbon-enriched coating to reduce friction on the folding part of the rotary piston wing

2. Rotating piston precision machining

In this rotary piston engine, the compression process is pre-compressed outside the cylinder by a supercharger, converted to a high density state, and then supplied to the cylinder.

It was mainly used in diesel engines, but recently, it is also common in gasoline engines. The optimum efficiency can be further increased by cooling the compressed air through the supercharged air cooler before supplying the compressed air to the cylinder. Since the temperature is so high, cool it with coolant or external air before supplying it to the cylinder and then to the cylinder. This further improves filling efficiency and is effective in increasing output.

The cooling advantages of the charge air are:

1. Increase the optimum efficiency.

2. In other cases, the lower the air temperature, the higher the mass of the air supplied to the cylinder. In other words, the optimum efficiency increases.

3. Reduce the heat load in the cylinder (cylinder cooling effect).

4. Improve filling efficiency.

5. Prevent knocking.

Hydrogen gas (fuel cell car) that converts hydrogen gas into electric energy to get electric motor driving power has been developed and is in the beginning stage of practical use. To obtain hydrogen, water has to be electrolyzed. Poor economical due to a lot (high price of hydrogen car)

The present invention converts hydrogen gas into explosive energy and obtains more power than a hydrogen fuel cell automobile engine, and uses a new rotary piston engine instead of a conventional reciprocating engine to produce hydrogen gas as a fuel. To produce

The present invention is simple and excellent in performance (hydrogen) while generating a continuous power while repeating the suction, compression, explosion, and exhaust processes while engaging the pair of rotary pistons and the pair of gear shafts by rotating the inside of the engine housing 360 °. Gas) (pure water) is an internal combustion engine

In the reciprocating piston engine, the inside of the cylinder is always very hot due to the suction compression explosion and exhaust process in one cylinder and one cylinder. Especially during the suction compression process, the temperature inside the cylinder rises rapidly and the piston's heat of compression reaches In the case of hydrogen gas or pure gasoline, which has a low ignition point, the piston reaches the top dead center, and the electron ignition occurs, the crank reverses and the parts in the suction process are damaged. Due to these problems, it is not suitable to use hydrogen gas or pure gasoline as fuel in the reciprocating piston engine. However, in this rotary piston engine, the suction compression process of the engine to prevent the high temperature in the cylinder generated in the piston reciprocating engine is prevented. Is compressed outside the cylinder by a supercharger to cool the high heat generated during the compression process through a cooler, and then converts it into a dense state and supplies it to the combustion chamber. This reduces the heat load on the cylinder and Not only is the cooling effect large, but the mass of the intake air is increased and the effect is also increased. That is, the mass of air supplied to the rotary piston engine combustion chamber has a high temperature, and the mixture gas supplied to the compression temperature combustion chamber does not have a high temperature. Also in the supercharger the air pressure is automatically adjusted I am bowed. Unlike the reciprocating engine, the rotary piston engine is highly efficient, making it suitable for hydrogen gas automobile engines.

As described above, a new rotary engine that solves all the problems of the gasoline engine is intended to manufacture a new type of engine with reduced engine manufacturing cost and superior performance.
