Abstract

The reduction of carbon dioxide emissions takes highest priority in engine development. Due to high fuel prices and an increasing ecological awareness, many customers today prefer fuel-efficient vehicles. The carbon dioxide target values of the European Union reinforce this trend. As a consequence, new part-load concepts are being developed for gasoline engines and a further downsizing is required. The acoustic behavior of these new combustion processes is in part considerably different from previous conventional gasoline engine technology. The research study No. 914 of Forschungsvereinigung Verbrennungskraftmaschinen (FVV) carried out at the Institute of Internal Combustion Engines (VKA) of RWTH Aachen University analyzed the cause-and-effect-relationship between these new charge cycle and combustion concepts and engine acoustics respectively.
