Cylinder and piston co-rotating type engine

Abstract

The invention relates to a cylinder and piston co-rotating type engine which comprises a rotor and a stator. A cylinder rotor is formed by a column type component and a plurality of cylinders shifting a certain distance on the periphery of the column type component, and an output shaft is inserted in the center of the column type component. A stator assembly is formed by arranging a stator housing, an upper housing cover and a lower housing cover in parallel, wherein the housing covers are provided with intake and exhaust vents, and the stator housing has an oval cavity. When the rotor rotates in a non-eccentric mode in the stator, a rotor bearing at the tail end of a piston in the cylinders can slide on the oval inner side wall of the stator so that the capacity of the cylinders can be changed periodically, a four-stroke principle is realized, and thus the engine has a high ratio of power to weight.

Description

a technical field [0001] The invention relates to a cylinder-plug co-rotating engine, in particular to an engine in which a cylinder and a piston continuously rotate in an elliptical space to realize the four-stroke principle. 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...

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.

4. The shape of the triangular rotor and the shape of the cylinder are very precise, and the processing cost is high
