Engine piston with silencing effect

Abstract

The invention relates to the technical field of engine pistons, and discloses an engine piston with a silencing effect. The engine piston with the silencing effect comprises an air cylinder and a piston head, and a through hole communicating with the interior of the air cylinder is formed in the top of the air cylinder. According to the engine piston with the silencing effect, silencing grooves are formed in the outer wall of the piston head, and silencing pads are arranged on the groove inner side walls of the silencing grooves, so that noise generated by friction between the piston head during movement and the air cylinder is in contact with the silencing pads through the silencing grooves, and then noise is absorbed by the silencing pads; a silencing sheath is arranged outside the air cylinder, so that whennoise generated by a rotating head during rotating is in contact with the silencing sheath, the noise is absorbed by the silencing sheath, and then the problems that due to the fact that friction between the piston during use and an air cylinder wall occurs, the relatively high noise is generated, moreover, due to the fact that a device for eliminating noise is not arranged, the noise is directly transmitted to the outside of the air cylinder, and is transmitted to the periphery, and then the sound pollution can be relatively serious, the normal life of the crowd is influenced, and the development requirements of modern society are not met are solved.

Description

technical field [0001] The invention relates to the technical field of engine pistons, in particular to an engine piston with noise reduction effect. Background technique [0002] Piston engine is also called reciprocating engine. It is an engine that uses one or more pistons to convert pressure into rotational kinetic energy. Piston engine is a kind of heat engine. It is powered by fuel such as gasoline and diesel. It is composed of piston, connecting rod, crankshaft, valve train, propeller reducer and case. [0003] At present, the existing engine pistons on the market are simple in structure, but because the pistons will rub against the cylinder wall when they are in use, they will generate relatively loud noises, and there is no noise elimination device, causing the noise to be directly transmitted to the outside of the cylinder and to the surroundings. The sound pollution is relatively serious, which affects the normal life of the crowd and does not meet the developmen...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an engine piston with a sound-absorbing effect, which has the advantages of eliminating noise, etc., and solves the problem that the existing engine piston on the market has a simple structure, but the piston will rub against the cylinder wall during use. , produces a lot of noise, and there is no noise elimination device, causing the noise to be directly transmitted to the outside of the cylinder and to the surroundings, causing serious sound pollution and affecting the normal life of the crowd, which does not meet the development needs of modern society.
