Calculated studies of the influence of the composition and properties of fuel on the working process of the engine have been carried out according to the developed method, includinga computer program for calculating of the working process, models for the flow of fuelin the nose of the fuel nozzle, and the development of fuel steam in the combustion chamber. Regression and graphical dependencies of the specific indicator fuel consumption andspecific emission of nitrogen oxides on the elemental composition, density, viscosity andsurface tension of the diesel fuel are obtained, which allow to evaluate the influence of the above composition and properties on the performance of the process. As a result of the conducted researches, it was concluded that for diesel engines it is better to use buthanol, incomparison with methanol and ethanol, the composition and properties of which provide the best fuel-economic and ecological parameters of the engine.
