Slide-cylinder gas distribution suspending piston engine

Abstract

The invention discloses a slide-cylinder gas distribution suspending piston engine which comprises a cylinder, pistons and a slide cylinder, wherein the pistons are completely or partly arranged inside the cylinder; the pistons and the cylinder is arranged in a suspending way or exactly suspending way in the whole or part stroke range between a top dead center which is arranged on the cylinder andcorresponding to a top dead center of the piston and a bottom dead center that is arranged on the cylinder and corresponding to a bottom dead center of the piston; the pistons are contacted with theslide cylinder in a sealing and sliding way; the slide cylinder is controlled to be contacted with the cylinder in a sealing way or separated from the cylinder by a slide cylinder timing control mechanism; and a side wall gas distribution channel is arranged at the interface where the cylinder is matched with the slide cylinder. As the position of a gas valve seat hole arranged at the side of thecylinder is on a sealing section of the pistons, engine oil can be avoided being blown into an air channel, the engine oil which is blown into the air channel is prevented from entering a combustion chamber or being directly discharged into the atmosphere, the environmental pollution can be reduced, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to the field of engines. Background technique [0002] In a traditional two-stroke engine, the piston is in a sliding and sealed connection with the inner wall of the cylinder. In order to maintain the relative movement between the piston and the cylinder, it is necessary to use oil to lubricate the piston and cylinder. Although this has played a lubricating effect, in the structure where the air passage of the two-stroke engine is arranged on the side wall of the cylinder, the machine oil will enter the combustion chamber with the air flow, and the combustion of the machine oil in the combustion chamber is insufficient. The emission performance of the two-stroke engine is reduced, excessive harmful emissions are produced, and the environment is polluted, or the engine oil will directly enter the exhaust passage and be discharged into the atmosphere with the exhaust gas of the engine, causing more serious environmental pollution. ...

Although this has played a lubricating effect, in the structure where the air passage of the two-stroke engine is arranged on the side wall of the cylinder, the machine oil will enter the combustion chamber with the air flow, and the combustion of the machine oil in the combustion chamber is insufficient. Reduce the emission performance of the two-stroke engine, produce excessive harmful emissions, pollute the environment, or the engine oil will directly enter the exhaust passage, and be discharged into the atmosphere with the engine exhaust gas, causing more serious environmental pollution

In a traditional four-stroke engine, since the intake and exhaust valves are all set on the cylinder head, no matter whether the multi-valve technology or the traditional single-valve technology is adopted, the size of the intake and exhaust valves is limited by the cross-sectional area of ​​the cylinder. Affect the intake and exhaust area of ​​the intake and exhaust valves, making the intake and exhaust efficiency low
