The Experiment Research on Related Factors of Influencing Combustion Noise of Diesel Engine

Abstract:

The noise of Diesel engine is the main source of vehicle noise, and engine noise is divided to 3 parts: the mechanical noise, the air flow noise and combustion noise. Combustion noise is the main part of in the three. In this paper, the combustion noise variation of a vehicle diesel with parameters of engine speed, engine load, pump and injector were analyzed by experiment method, the relationship between combustion noise and the double-peak of cylinder presser rise rate were analyzed carefully, some conclusions such as the second peak of PRR(pressure rise rate) is the suitable factor reflecting combustion noise and combustion noise is the function of diesel load were gotten.
