The influence of alternative fuel composition for diesel engines on the performance of D-21 tractor diesel is considered. The influence on the thermal calculation of the engine and on the combustion process of alternative fuel is investigated. The thermal calculation of the engine is carried out when working on a mixture of different composition to determine the possible influence on the engine power. Knowing the nature of the change in cycle feed and the elemental composition of the fuel mixture, we can analyze their effect on the change in the calorific value of the mixture (Hu), the coefficient of excess air (α) and other engine performance. The obtained design and experimental data on fuel can be verified experimentally during bench tests of the engine.
