aref2 One of the types of bio-fuel is diesel mixed fuel (DMF) prepared by mixing mineral diesel fuel with vegetable oil. The most common and widespread thing as a biological component of diesel mixed fuel is rape oil. Though, in spite of its well-known valuable properties as a biological source of heat energy, we cannot exclude the possibility of using vegetable oils of other crops. Wild cabbage which has very much in common with rape in their botanic and biological properties re-fers to these oil-bearing crops. In order to estimate the feasibility of using wild cabbage oil as a biological component of DMF there were tests held to investigate the fat-acid composition, physical and heat-producing properties of natural and ul-tra-sonic treated wild cabbage oil and DMF. The volume ratio of wild cabbage oil and mineral fuel was 25:75, 50:50, 75:25, 90:10. The results of comparative ex-perimental tractor diesel 411/12.5 tests when working on above mentioned mixed fuels and mineral fuel were shown according to power and fuel-economic indexes. For preparation DMF directly in the tractor running process the two-fuel feed sys-tem was developed and patented. This system along with regular units and mecha-nisms, additionally contains a tank with vegetable oil, a mixer with batchers with a drive gear from step-by-step (linear) electric motors which are electrically con-nected with electronic control package and sensors of a loading and high-speed mode. The volume ratio of wild cabbage oil and mineral fuel in DMF coming to the diesel engine combustion chamber is changing depending on tractor running conditions
