Information

The main function of the car muffler is to reduce the exhaust noise of the engine and make the high temperature exhaust gas can be safely and effectively discharged. As part of the exhaust pipe, the muffler should ensure smooth exhaust, low resistance and sufficient strength. The muffler must withstand the high temperature exhaust gas of 500 ℃ ~ 700 ℃ to ensure that it will not be damaged or lose the muffler effect within the specified driving mileage of the car.
Automobile noise mainly comes from automobile exhaust noise. If the muffler is not added, the noise can reach more than 100 decibels at a certain speed. The second is the engine noise and tire noise. The engine noise can reach more than 90 decibels when the car is running normally, while the tire noise can reach about 95 decibels when the vehicle speed is above 90 km/h. Therefore, adding a muffler to the exhaust system can reduce the exhaust noise of the car by 20-30 decibels. In terms of engines, replacing diesel engines with gasoline engines can reduce engine noise by 6-8 decibels.
