Study of indicators of the working process of tractor diesel when working on ethanol and rapeseed oil

Abstract

Abstract The use of alternative fuels derived from natural gas, coal, and renewable energy sources in tractor diesel engines (TDE) will solve the problem of replacing petroleum fuels, significantly expand the raw material base for obtaining motor fuels, and reduce the negative impact of motor vehicles on the environment. The use of alternative oxygenate fuels, such as ethanol (E), in diesel engines is particularly promising. As a result of the analysis of the conducted studies, it was found that it is possible to organize the working process in the cylinder of a TDE when it operates on E and rapeseed oil (RO), with their separate supply directly to the cylinders and ignition from the ignition fuel (pilot) with a high cetane number. As a starting fuel, it is possible to use RO, which is capable of self-ignition due to its physical and chemical properties. At the same time, it is expected to improve the performance of the working process, environmental and efficient performance of the TDE with the complete replacement of diesel fuel (DF).
