Internal combustion engine with double rotor pistons

Abstract

The invention relates to the field of power machinery, in particular to an internal combustion engine with rotor pistons. The internal combustion engine is characterized in that 1, the two pistons which are mounted oppositely intermittently rotate around a center shaft in a cylindrical cylinder, air suction, compression, explosion and exhaust stoke are completed, energy of exploded gas acts on side surfaces of the pistons, output shafts are directly pushed to rotate, and the problem of energy dissipation of an engine with a reciprocating piston due to change of an included angle between a crank and a connecting rod is avoided; 2, compared with an engine with a reciprocating piston and a triangular rotor, the internal combustion engine does not have a reciprocating part or a movable valve or components thereof, does not realize eccentric movement, accordingly does not cause structural vibration, and is low in self consumption; 3, compared with a triangular rotor engine adopting a linear sealing component, the engine realizes surface sealing, does not need parts such as sealing strips and the like which are difficult in processing and easy to be worn, and is fine in sealing performance and high in reliability; 4, abrasion rate is low, abrasion of a main portion only depends on the abrasion degree of a bearing; and 5, the total engine is simple and compact in structure and high in thermal efficiency.

Description

Technical field: [0001] The invention relates to the field of internal combustion power machinery, in particular to a rotor-piston internal combustion engine. Background technique: [0002] The piston-type internal combustion power machinery currently used in the world is a piston-type internal combustion engine that performs suction, compression, explosion and exhaust strokes in the cylinder through the piston. This is the mainstream power system after the industrial revolution and is widely used in industry and agriculture. In the fields of transportation, military, etc., it is divided into reciprocating piston (Otto / Diesel) engines and triangular rotor piston (Wankel) engines that have been put into practical use in recent years. [0003] The reciprocating piston engine has three inherent defects. One is that the reciprocating motion of the piston and connecting rod consumes a lot of energy; The effect of rotation, the rest of the force is dissipated in vain; the third i...

AI Technical Summary

Problems solved by technology

Fourth, the sealing components of the Wankel rotary engine are small in size, high in precision, complex in structure, and difficult to manufacture, and it is difficult to achieve long life in a high-temperature, high-speed, and vibrating working environment

Fifth, its compression ratio is not easy to make larger, it can only be used as an ignition type gasoline engine, and cannot be used as a compression ignition type diesel engine

The above shortcomings determine that it is difficult to be widely used
