Noise reduction is one of the highest prior target for diesel engine because of the more and more strict engine noise limits, diesel engine noise has been drawing significant attention from automotive manufacturers. To effective reduce the noise level of a diesel engine the first step is the identification of different engine noise sources. The design and development of modern diesel engines is marked by a reduction in exhaust gas emissions and increase in specific power and torque.Exhaust noise is one of the major contributors to noise from vehicles powered by internal combustion engine. For the same power rating, diesel engines are noisier than gasoline engines, since the combustion characteristics of diesel engines produce more harmonics than slower combustion of gasoline.This paper reviews different noise sources and methods are available for noise reduction of diesel engine.
