Abstract: This paper discusses the source of combustion noise in an indirect injection diesel engine, and how it can be reduced through the use of healed inlet air. Data are also presented that show the relation between ignition delay and sound level. Correlations for ignition delay are discussed, and results are presented that show a slight modification to the Watson correlation.

Keywords: heated air inlets; IDI diesel engines; indirect injection; engine noise; noise reduction; NOx emissions; vehicle noise; combustion noise; vehicle emissions; ignition delay; Watson correlation.
