A study of the effect of post injection on combustion and emissions withn premixing enhanced fueling strategies

摘要

An empirical investigation was carried out in a compression ignition engine to characterize the effect of the post injection timing on the post injection power production, the exhaust temperature, and the exhaust gas composition. Due to the potential emission reduction benefits of alternative fuels, numerous fuel injection strategies were investigated, including direct injection diesel, dual fuel diesel and ethanol, dual fuel diesel and butanol, and direct injection butanol. For all of the teste
