In a rotary piston engine, a pair of rotary pistons engages with the timing gear shaft to rotate within the engine housing, with the protruding blades attached.

(Fig. 4-2.3

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] Piston Reciprocating General Principle

[2] Vankel Institute, developed by Felix wankel

The rotary piston engine of the present invention is an engine having more output and performance corresponding to a four-stroke four-cylinder reciprocating piston engine. In the piston reciprocating engine, the suction compression explosion exhaust process is performed every two revolutions of the crankshaft, and one explosion force is generated in the process. However, in the rotary piston engine, once the rotating piston generates one explosion force in one revolution, two pairs of pistons get two explosive forces. Therefore, the reciprocating four-stroke four-cylinder can achieve the performance and more output. And small size makes production cost small. An important object of the present invention is to reduce the friction on 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 are generated in the air, and it is difficult to handle hydrogen gas as extremely fast diffusion in the air. The research and development of hydrogen gas was applied to reciprocating internal combustion engines to obtain power as an energy source, but there are many problems in the structure of the engine, which has not been put into practical use until now (hydrogen gas fuel cell vehicle commercialization)

Hydrogen gas is applied to the reciprocating piston engine Suction compression causes spontaneous explosion to reverse the crankshaft and break the components of the suction process. On the other hand, when the engine is operated by lowering the compression pressure of the cylinder to an appropriate level, the output is weak and economical. The piston rotary engine of the present invention is an engine that solves all the above problems and is a simple and highly efficient engine that generates power to a low pressure engine having a low compression process. In rotary engines, a pair of rotary pistons generate power as they rotate 360 ° in the engine housing. Unlike reciprocating engines, a rotary piston directs the initial explosion pressure of the cylinder to direct torque and is designed to push both pistons. to be

The initial pressure of the cylinder is the highest when the volume of the cylinder is the smallest. The larger the volume of the cylinder, the lower the pressure of the cylinder. Therefore, it is most important how quickly the high pressure of the cylinder can be used to obtain a strong rotational force by using an efficient mechanical device before the cylinder volume increases and the pressure drops.The piston reciprocating engine generates a strong pressure at the top dead center of the cylinder. However, since the angle of the piston cone crankshaft begins to rotate from the vertical, it cannot produce a strong force at the beginning of the explosion. (Fig. 5-1)

At the point where the piston cone crankshaft moves out of the vertical angle and the rotation angle increases and a force can be applied, the pressure of the cylinder drops and the cylinder starts to open the exhaust valve before the piston reaches the bottom dead center. However, in the rotary piston engine, the position of the cylinder does not start from the vertical as in the reciprocating engine, but at the 90 ° proximity point where the 45 ° angles meet each other in the center of each of the A piston B pistons. The explosion pressure in which the explosion occurred in advance pushes both rotating pistons, leading to a strong rotational force from the beginning of the explosion (Fig. 5-3).

In the Vankel engine, the explosion driving force acts as a right angle to the rotating body and acts as a disturbing force at the bottom of the explosion chamber center point (FIG. 5-2).

However, in the present invention, the force of the explosion chamber acts in all directions in the rotational direction, so that the efficiency of the power torque is high, which is the greatest fuel saving effect and the engine efficiency.

Looking at the structure of the reciprocating engine and the rotary piston engine, when the reciprocating engine and the rotary piston engine have the same explosion pressure of the cylinder, the reciprocating engine moves up and down inside the cylinder without the center point of the piston itself. The first explosion pressure of the engine, such as crankshaft, camshaft, and flywheel driving energy loss, is mostly lost as reactive loss energy. In a four-stroke reciprocating piston engine, with these problems, the crankshaft gains one explosion in the course of two revolutions. The actual effective drive force is less than 25% of the original explosion pressure.

The rotary piston engine does not require reciprocating engine parts, so there is no energy loss and strong force in the engine structure.

The advantages of the rotary piston engine are:

1. It is a rotary piston with no recoil resistance.

2. Small number of parts

3. Less friction loss

4. There is no exhaust valve

5. It is a rotary piston oil chiller

6. No fry wheels

7. Low compression because the compression process is low pressure

8. The piston rotary shaft is embedded as a bearing

As described above, it is a hydrogen gas engine that completely solves the problems caused by the reciprocating engine and solves the problems of high pressure and high heat in the cylinder, which is a barrier in the hydrogen gas engine.

In this rotary piston engine, the compression process is pre-compressed outside the cylinder by the supercharger to convert it into a high density state and then supply it to the cylinder. It was mainly used in diesel engines, but recently, it is also common in gasoline engines. Becoming

The volumetric efficiency can be increased by cooling the compressed air through the supercharged air cooler before supplying the cylinder to the cylinder. The air compressed by the supercharger is so hot that it is cooled by coolant or external air before supplying it to the cylinder. And then supply it to the cylinder. This improves the filling efficiency and increases the power output.

The cooling advantages of the charge air are as follows.

1. Increase volumetric efficiency.

2. If the conditions are the same, the lower the temperature of the air, the higher the mass of the air supplied to the cylinder.

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

4. Improve filling efficiency.

5. Prevent knocking.

A hydrogen gas (fuel cell) automobile has been developed that converts hydrogen gas into electric energy to obtain electric motor driving power. In order to obtain hydrogen, water has to be electrolyzed, and in the process of electrolysis, power consumption is high and production costs are high, resulting in low economic efficiency (hydrogen gas fuel cell automobile is expensive).

The present invention is to convert the hydrogen gas into explosive energy to obtain more power than the hydrogen fuel electric vehicle engine, the hydrogen gas as a fuel in a new rotary piston engine instead of the conventional reciprocating piston engine is excellent in performance and low production cost Intended to produce an institution.

The present invention is simple and excellent in performance (hydrogen) in a structure that continuously generates power while repeating suction, compression, explosion, and exhaust processes while engaging a pair of rotary pistons and a pair of gear shafts to rotate 360 ° in the engine housing. 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 the top dead center. 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 is used to prevent the high temperature in the cylinder generated by the piston reciprocating engine. 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.
