What to Do About Loud Engine Noise?

[MacZoe]

The solutions for loud engine noise are: 1. Install some high-grade sound-absorbing foam materials on the engine cover to suppress vibrations caused by the hood; 2. Inspect and replace the intake and exhaust pipes if necessary; 3. Use insulated pistons to increase the combustion chamber wall temperature, shorten the ignition delay period, and reduce combustion noise in direct-injection diesel engines with space atomization combustion systems. An engine is a machine that converts one form of energy into another, typically transforming chemical energy into mechanical energy. The function of an engine is to convert the thermal energy of gasoline into mechanical energy by burning it in a sealed cylinder, where expanding gases push the piston to perform work, thereby providing power for the vehicle.
