The study of diesel noise control.

Diesel engine will have a great noise when it works. The noise sources include combustion noise, mechanical noise and intake and exhaust noise, etc. To reduce the internal combustion engine noise, the noise source and dissemination way must be considered. Reducing the source noise is the most basic and the most direct effective action that it includes reducing the noise exciting force and exciting force response and so on. The main method in the diesel engine burning noise 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 method is to improve and optimize exhaust silencer for intake and exhaust noise. [ABSTRACT FROM PUBLISHER]
