Abstract: CI engine will have a great sound when it works. The sound sources include combustion sound, mechanical sound and intake and exhaust sound, etc. To reduce the internal combustion engine sound, the sound source and dissemination way must be considered. Reducing the source sound is the most basic and the most direct effective action that it includes reducing the sound exciting force and exciting force response and so on. The main method in the CI engine burning sound aspect is formerly to adjust feed time and advance angle, to use the new combustion chamber and so on. The most effective and the most common methods are to improve and optimize exhaust silencer for intake and exhaust sound.
