The relevance of this issue is confirmed by numerous studies of alternative motor fuels in particular from renewable sources of raw materials (biomass) studied in various regions of the Russian Federation and abroad. As a raw material for the production of diesel blended fuels, Maslenica cultures not used in the food industry are attractive, such as safflower, redhead, rape, prune, Abyssinian crumb and castor oil. At present, there is a growing need in the Russian Federation for ricin oil used in military, chemical, machinebuilding, radio electronic, printing, paint, medical, cosmetic and other industries. As a result of the processing of castor beans by cold pressing in residual meal or husk, there remains about 10% of the oil that can be recovered by processing the meal using extraction technology to produce a technical ricin oil with the possibility of using it as a raw material for the production of paint and varnish, lubricants and diesel mixed fuel. However, the viscosity of ricin oil is an order of magnitude higher than that of diesel fuel, so it must be used in a mixture with low-viscosity components. As an additive to ricin oil, mineral oil fuel and bioethanol can be used due to which the viscosity of the mixture decreases significantly, the cloud point and crystallization temperature decreases and makes it suitable for use in standard diesel power systems in terms of high-quality spraying, low-temperature properties. As a diesel mixed fuel, a mixture of ricin oil (RitzM), bioethanol and summer diesel fuel according to GOST 305-2013 was investigated. On the basis of the performed heat calculation, the operating cycle indices are determined, the dependences on the concentration of the components of the mixture fuel are shown. Based on the results of the theoretical calculation, the obtained indicators were compared with diesel fuel.
