The use of reusable fuel injection with the aim of improving the economic and environmental performance of the diesel engine

Abstract

Abstract The current trend in the development of motor-and-tractor diesel engines imposes tough requirements on fuel equipment and the fuel supply process. The implementation of it is difficult to combine with the requirements of reducing heat generation at the initial stage of combustion and the rate of pressure increment to reduce exhaust emissions and engine noise. A decrease in the duration of the injection process and an increase in the volumetric feed rate lead to a growth in the cycle dynamism factor and an increase in the operation noise. This scientific article discusses the use of multiple injection of fuel in a diesel engine to reduce the emission of nitrogen oxides, smoke and particulate matter by improving the heat transfer processes, the mixture formation and, as a result, heat generation. Low exhaust gases toxicity and smokiness values are achieved.
