Engine sound-absorbing air cylinder cover

Abstract

The invention discloses an engine sound-absorbing air cylinder cover comprising a cylinder cover main body, a cooling cavity, an oil cavity and a liner. The cooling cavity is formed in the obverse side of the cylinder cover main body, the oil cavity is formed in the left side of the cylinder cover main body, the liner is mounted on the right side of the cylinder cover main body, and a fixing pieceand a reinforcing metal plate are arranged on the side walls of the two ends in the cylinder cover main body; and an air hole unit is arranged in the middle of the bottom of the cylinder cover main body and comprises an air inlet and an exhaust port, and one end of the bottom of the cylinder cover main body is provided with an ignition coil mounting hole, a control valve mounting hole and a cam shaft mounting hole. According to the engine sound-absorbing air cylinder cover, the strength of the cylinder cover main body is higher, and the cylinder cover main body is firmer and is not prone to being damaged after being used for a long term; the cooling cavity and the cylinder cover main body are both provided with sound-absorbing parts so that noise generated in the operating process of an engine can be reduced, noise pollution is reduced, meanwhile, the cooling cavity can be matched with cooling equipment to cool the engine, and thus the engine is protected.

Description

technical field [0001] The invention relates to the technical field of engine accessories, in particular to an engine sound-absorbing cylinder head. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living standards, car comfort has become an important indicator that people consider when buying cars. In recent years, engine technology has developed rapidly, and the explosion pressure in the cylinder has continued to increase. The vibration and noise generated by the engine during operation are also increasing, causing noise pollution, and in the prior art, the cylinder heads outside the current automobile engine are mostly thin-walled shell-shaped parts, and their strength is not very high , it is easy to be damaged after receiving vibration for a long time. At the same time, the heat dissipation effect of the existing cylinder head is not good enough, and the heat in the engine is not easy to dissi...

[0002] With the rapid development of the automobile industry and the continuous improvement of people's living standards, car comfort has become an important indicator that people consider when buying cars. In recent years, engine technology has developed rapidly, and the explosion pressure in the cylinder has continued to increase. The vibration and noise generated by the engine during operation are also increasing, causing noise pollution, and in the prior art, the cylinder heads outside the current automobile engine are mostly thin-walled shell-shaped parts, and their strength is not very high , it is easy to be damaged after receiving vibration for a long time. At the same time, the heat dissipation effect of the existing cylinder head is not good enough, and the heat in the engine is not easy to dissipate in hot weather, which affects the normal use of the engine. Therefore, the present invention proposes a sound-absorbing cylinder head for the engine. To solve the problems existing in the prior art
