Pressurizing type engine cylinder and automobile engine

Abstract

The invention discloses a pressurizing type engine cylinder and an automobile engine, and relates to the technical field of automobile engines. An engine body, pressurizing devices and cylinder bodiesare included. The tops of the cylinder bodies and the top of the inner wall of the engine body are fixedly connected. One sides of the pressurizing devices are fixedly connected with one sides of thecylinder bodies. Each pressurizing device comprises an air inlet pipe, wherein the bottom end of the air inlet pipe communicates with the top of the pressurizing device, the top end of the air inletpipe penetrates through the engine body and extends to the top of the engine body, fixing grooves are formed in the parts, located on the two sides of the surface of the air inlet pipe, of the top ofthe inner wall of the pressurizing device, the tops of the inner walls of the fixing grooves are fixedly connected with clamping springs, and the bottom ends of the clamping springs penetrate throughthe fixing grooves and extend to the bottoms of the fixing grooves. According to the pressurizing type engine cylinder and the automobile engine, air pressure can be increased, air pressure control isaccurate, the air inlet efficiency of the automobile engine is improved, the power of the engine is improved, and oil consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile engines, in particular to a supercharged engine block and an automobile engine. Background technique [0002] The car engine is the device that provides power for the car. It is the heart of the car and determines the power, economy, stability and environmental protection of the car. According to different power sources, car engines can be divided into diesel engines, gasoline engines, and electric car motors. As well as hybrid power, common gasoline engines and diesel engines are reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy of piston motion and output power externally. Gasoline engines have high speed, low mass, low noise, easy starting and low manufacturing cost. , The diesel engine has a large compression ratio, high thermal efficiency, and its economic performance and emission performance are better than gasoline engines....
