Investigating the noise generation of a compression ignition engine at different filters

Abstract: Noise is a very important phenomena for passenger comfort in a vehicle. Engine of the vehicles produce disturbing noises in different frequencies. In the application of acoustic, there are different filters to predict the sound pressure level and disturbing noises. The aim of the present study is to investigate the noise characteristic of a compression ignition engine at different weighting filters. In the experiments, the engine was fuelled with low sulphur diesel and sunflower biodiesel fuels and it run at d… Show more

“…1 -pk and Tkpressure and temperature after the compressor are taken as parameters of the state at the inlet to the cylinder. In the absence of pressurization, pc=p0, tc=t0, where p0 and t0 are, respectively, the pressure and temperature of atmospheric air, in other words, the parameters of the state of charge at the compressor inlet [10,13,15].…”
