Research objective is to provide the set temperature condition of mixed mineral and vegetable fuel (MMVF). The use of fuel systems with smart heating will increase the volume of mineral diesel fuel, replaced by renewable re-sources. The technique and results of research of heating with external and internal supply of heat and also with hashing of the heated environment are given. Researches were conducted on specially developed laboratory in-stallation. MMVF on the basis of flax, soy and rape oils were investigated. Concentration of a vegetable component made 40% on volume. The 1000 W external heater and also the 1000, 500 and 300 W external heaters of all types were used. It is established that when heating MMVF the external source of warmth provides good heating on all volume without use of extra for mixing, overheating is 50% of necessary size. When leading warmth without hash-ing of MMVF warming up came from an internal source (the 1000 W heater) unevenly, the unevenness was 60%. When using mechanical mixing of MMVF with heating from an internal source of warmth the unevenness of warm-ing up was 3.1…4.65% depending on heater power. By results of a research it was established that when using the heater with a power of
300 W when heating 1 liter of mixed mineral and vegetable fuel on the basis of rape oil with the maintenance of a vegetable component of 40% on volume time of heating to 60±2 °C was 230 s, the unevenness of heating was 3.1%, overheating was 3.1%. Recommendations about the most rational modes of heating of MMVF in a power supply system of the diesel are made.
