Precession rotary engine

Abstract

The invention relates to a precession rotary engine. The precession rotary engine comprises a rotor assembly composed of a disc rotor member and an output shaft member and a cylindrical stator composed of an upper case and a lower case which are opposite, wherein rotors rotate in the stators in the rotation-precession ratio of 1:3 so that the volumes of six cylinders formed between the rotors andthe stators change periodically; a pair of gas ports on one side of the circumference of the entire case are used to realize air admission and exhaust and a spark plug on the other side of the case is used to strike a light, thus the four-stroke principle can be realized and the six-cylinder engine with very large power-weight ratio can be formed.

Description

a technical field [0001] The invention relates to a precession rotor engine, in particular to a high-power engine in which a disk-shaped rotor is installed in a stator to realize precession rotation. Two background technology [0002] Among the existing engines, the ones with more mature technology are mainly reciprocating piston engines and Wankel triangular rotor engines for vehicles. Wherein the reciprocating engine has several problems that cannot be avoided. 1. The reciprocating motion makes the limit speed of the engine lower. 2. The reciprocating engine is provided with an air exchange valve mechanism, which not only increases the volume of the whole machine, but also increases the weight of the whole machine. 3. The crankshaft and connecting rod are used for power transmission. When the piston is close to the top dead center and the bottom dead center, the effective force arm of the gas expansion force on the crankshaft is very small, the expansion force in the cyl...

AI Technical Summary

Problems solved by technology

1. The reciprocating motion makes the limit speed of the engine lower

2. The reciprocating engine is equipped with a ventilation valve mechanism, which not only increases the volume of the whole machine, but also increases the weight of the whole machine

3. The crankshaft and connecting rod are used for power transmission. When the piston is close to the top dead center and the bottom dead center, the effective force arm of the gas expansion force on the crankshaft is very small, the expansion force in the cylinder cannot be fully exerted, and the energy conversion rate is low.

4. The power-to-weight ratio of the whole machine is too small, so it is not suitable for application in the aviation direction

1. The eccentric rotation of the triangular rotor will produce a lot of vibration

2. The shape of the cylinder formed between the triangular rotor and the cylinder wall is narrow and long, which makes the fuel combustion insufficient

3. When the engine is working, the pressure of the expanded gas in the cylinder is decomposed, and the effective torque is very small, so that the energy conversion efficiency of the engine is lower than that of the reciprocating engine, and the fuel consumption is high. It is only used in high-speed racing cars or airplanes, and is not suitable for civilian use.
