Results of the calculation of mass emissions of harmful substances with exhaust gas and the fuel consumption of a diesel vehicle with the use of a mathematical model

М. Pavlovskyi

The tendency of improving the environmental performance of cars with modern diesel engines in use, systemic gradual transition from regular supply of diesel fuel to power alternative fuel types are examined in the article. The object of research – the impact of mixed biodiesel fuels for fuel-economic, environmental and energy performance car with a diesel engine. The purpose of research is to expand the fuel base of motor transport using alternative fuels. Research methods are experimental-calculated. Improving the environmental performance of cars with modern diesel engines equipped with an electronic control system, controlled gas turbine boost, an exhaust gas recirculation system and an electronic crankshaft speed control system, it is possible to ensure that the requirements of regulatory documents are met by a systemic phased transition from diesel power supply namely rapeseed oil methyl ester additives to regular diesel fuel. The formation of such a transition should take place on the basis of scientific research and experience in the use of alternative fuels. Optimization of the physical and chemical properties of mixed biodiesel fuels is one of the effective ways to reduce exhaust emissions and improve fuel economy. This is achieved by providing both the necessary physical and chemical properties of mixed biodiesel fuels, and narrowing their boundaries change, i.e. adaptation of fuels to diesel engines in use. Therefore, optimization of physical and chemical properties of mixed biodiesel fuels makes it possible to improve the efficiency of its use in modern diesel engines and reduce emissions of harmful substances from exhaust gases. The results of the article can be used as guidelines in the preparation and usage of mixed biodiesel fuels for road transport.
