Description

Effectual automobile-used silencer assembly of cooling

Technical Field

The utility model relates to the technical field of automobile accessories, in particular to an automobile muffler assembly with a good cooling effect.

Background

The automobile silencer is a part for reducing noise generated by the working of an engine of a motor vehicle, and can be divided into three types, namely a reactive silencer, a resistive silencer and an impedance composite silencer according to the silencing principle and structure, so that the exhaust noise of the engine is reduced, and high-temperature waste gas can be safely and effectively discharged. The silencer is used as a part of an exhaust pipeline and is required to ensure smooth exhaust, small resistance and enough strength. The muffler is subjected to high-temperature exhaust at 500-700 ℃, so that the muffler is not damaged or loses the muffling effect within the specified driving mileage of an automobile, and the automobile noise mainly comes from the automobile exhaust noise. If no silencer is added, the noise can reach more than 100 decibels at a certain speed. The second is engine noise and tire noise, which can reach over 90 db when the vehicle is running normally, and can reach about 95 db when the vehicle speed is over 90 km/h. Therefore, the silencer is added in the exhaust system, so that the exhaust noise of the automobile can be reduced by 20-30 dB. On the aspect of an engine, a gasoline engine is used for replacing a diesel engine, and the engine noise can be reduced by 6-8 decibels.

If the exhaust gas generated after the fuel oil is combusted in the engine is directly exhausted into the atmosphere, the gas pressure of the exhaust gas is suddenly reduced from high pressure to atmospheric pressure, so that very harsh noise is generated, and the exhaust gas generated after the fuel oil is combusted in the engine of the automobile has high temperature and needs to be radiated and cooled in time.
