Development of Index for Active Control of Lean Compression Ignition Combustion

点击翻译按钮获取中文摘要

Development of an index has been attempted, which is useful for combustion control to ensure high thermal efficiencies with reducing emvironmental impact and avoiding excessively high pressure rise rate in the engines utilizing the principle of premixed compression ignition combustion. As a result, a simple index has been proposed, which is based on the overall fuel mass fraction in a spray at the ignition. This index enables the prediction of the harshness of combustion and the mass of nitrogen oxides for the various injection conditions and the composition of fuels.
