Investigation of the effective performance of diesel engines running on methanol and rapeseed oil methyl ether

Currently, diesels are widely used as a power plant for the global automotive and tractor fleet. Undoubtedly, this cannot but affect the depletion of the world's fossil fuel reserves and the rise in prices for oil and petroleum products. On the other hand, due to the constant increase in the number of power plants and the deteriorating environmental situation, it is no less important to maintain the required level of purity of diesel (D) exhaust gases (EG). This raises the question of finding new alternative energy sources and using them in existing engines. An important task in this case is to maintain the power and economic indicators at the level corresponding to the serial engine. The paper presents the results of studies of the working process of D using methanol (M) and rapeseed oil methyl ether (ROME). The minimum ignition portion of rapeseed oil methyl ether is set, which ensures stable operation of the D both at low loads and at idle, and over the entire load characteristic. The required composition of biofuels for the D under study is determined and recommended as optimal. The effective parameters of the D under load conditions when operating on M and ROME are studied in detail. At the same time, experimental characteristics of the effective indicators of a D running on these alternative fuels are established.
