VEHICLE ENGINES. APPLICATION OF FUELS TYPES. EFFICIENCY
The urgency of the issue under consideration is stipulated by large-scale international research and is confirmed by the Russian Federation Government Decree No. 1-P of 08.01.2009 “Main Directions of State Policy in the Sphere of Energy Efficiency Improvement on the Basis of Using Renewable Energy Sources for the Period to 2020” and the Decree of the President of the Russian Federation from July 7, 2011 № 899 on priority directions of development of science, technology and technics in the Russian Federation.
According to the analytical agency “AUTOSTAT”, as of 2017 there are 3.7. million of trucks in the Russian Federation, of which the ecological standards “Euro-4” (and above) correspond only 14%, and annually are used more than 20 million tons for freight transport, which in the amount of processing oil to diesel gas oil is more than 70 million tons of diesel gas oil . From the above, it can be concluded that in order to solve the fuel issue and preserve the environment, it is necessary to study the performance of the diesel engine using diesel composite fuel and transfer of transport to alternative fuels.
As a raw material for the production of alternative fuels is attractive biomass, such as oilseeds and waste from processing plants.
As a result of the growing demand for ricinic oil by industry, it is necessary to study its application as a component for the production of diesel composite fuel.
However, the viscosity of ricinic oil is higher than that of diesel gas oil, so it can only be used as an additive to low-viscosity components. As a result of the addition of diesel fuel and bioethanol to ricinic oil, with preliminary preparation, decreases viscosity and are improved low-temperature properties. This mixture can be suitable for use on transport-technological machines, the point of view of qualitative spraying in areas with a moderate climate.
Based on the thermal calculation of the engine by the methods of Prokopenko R.M., Khorosh A.I., Bashirova R.M., are determined the parameters of the working cycle of the engine D-240 and are presented below the dependences on the concentrations of the components.
The article compares the obtained results with the indicators of traditional diesel gas oil.
