Pressure cylinder of motorcycle engine

Abstract

The invention provides a pressure cylinder of a motorcycle engine and belongs to the technical field of engines. By means of the pressure cylinder of the motorcycle engine, the problem of low supercharging efficiency of an existing pressure cylinder is solved. The pressure cylinder of the motorcycle engine comprises a cylinder body and a cylinder cover fixed to the top end of the cylinder body. The cylinder cover is provided with two one-way valve blocks for ventilation of the cylinder body, and the two one-way valve blocks are arranged in a splay shape. The inner space between the two one-way valve blocks is filled with filler. The filler is provided with an air intake hole and an air exhaust hole, wherein opening or closing of the air inlet end of the air intake hole is controlled by the corresponding one-way valve block, and opening or closing of the air outlet end of the air exhaust hole is controlled by the corresponding one-way valve block. The pressure cylinder of the motorcycle engine has high supercharging efficiency.

Description

technical field [0001] The invention belongs to the technical field of engines and relates to a supercharging cylinder of a motorcycle engine. Background technique [0002] Supercharged engines are more common in the automotive field. They are divided into turbocharged engines and supercharged engines. The principle of both is to increase the intake air volume through the rotation of the impeller, so that the mixed oil and gas can be fully burned to improve engine power. , to improve fuel economy. However, due to the small overall structure of motorcycles, it is difficult to adopt the supercharging structure of automobiles. Therefore, a supercharging cylinder is usually added around the combustion cylinder of the engine, and the piston in the supercharging cylinder is driven by the crankshaft to compress the gas to achieve supercharging. Such as Chinese utility model patent application (application number: 200720089284.1) discloses a kind of two-stroke gasoline engine, is m...

Problems solved by technology

However, due to the small overall structure of motorcycles, it is difficult to adopt the supercharging structure of automobiles. Therefore, a supercharging cylinder is usually added around the combustion cylinder of the engine, and the piston in the supercharging cylinder is driven by the crankshaft to compress the gas to achieve supercharging. Such as Chinese utility model patent application (application number: 200720089284.1) discloses a kind of two-stroke gasoline engine, is made up of working cylinder part and compressed gas cylinder part, and wherein working cylinder part comprises working cylinder block, and cylinder top both sides are respectively provided with inlet The air valve and the exhaust valve are equipped with an air storage chamber on the intake valve, and the compressed gas cylinder part includes a compressed gas cylinder block, in which a piston is installed, and the piston is installed on the connecting rod. The valve plate, check valve plate, and the check valve plate communicate with the intake valve through the air storage chamber, and the compressed gas cylinder can provide pressurized gas for the working cylinder, but it is precisely because the motorcycle engine has a compact structure that the volume of the pressurized cylinder It is difficult to make it larger, so the compression amount of the piston in a single stroke is small, and the boosting efficiency is low
