The invention has the characteristics of high fuel compression ratio, high power density, high efficiency, no eccentric center, low vibration severity, low noise, low exhaust, simple structure, good reliability, easy production and low processing cost.

Description

technical field [0001] The invention relates to an energy power engineering mechanical device, in particular to a double-rotor four-stroke ignition type internal combustion engine. Background technique [0002] An internal combustion engine is an energy power mechanical device that converts the thermochemical energy of fuel combustion into mechanical energy. Existing internal combustion engines are divided into three types: reciprocating internal combustion engines, gas turbines and rotor internal combustion engines. The reciprocating internal combustion engine has a piston and a crank-connecting rod mechanism as the main components, including two types of thermal cycles, two-stroke and four-stroke. Its disadvantages are complex structure, large volume, low thermal efficiency, and more exhaust pollutants. In particular, since the linear motion of the piston cannot directly realize the rotational power output, it must be converted by the crank-link mechanism. The reciprocati...
