With application of methods gas-liquid chromatographies it is determined fat-and-asid structure rapseed oils refined (the contents eruck acids С22:1 - 25,26 %). The molecular weight of oil - 932,33 kg / moll is designed, the approached total formula heigh-eruck (> 5 %) rapseed oils С60,5Н108,8О6 is written down. Relative shares of carbon, hydrogen and oxygen in rapseed oil : C = 0,779; Н = 0,118 and O = 0,103; the lowest heat of combustion Qн = 37,5 MJ/kg; L0 = 12,58 kg / kg and М0 = 0,434 kmoll/kg. Similarly for ethyl ethers of fat acids rapseed oils : formula С21,2Н39,6О2; C = 0,7795; Н = 0,1225 and O = 0,0980; the lowest heat of combustion Qн = 38,06 MJ/KG; L0 = 12,77 kg / kg and М0 = 0,44 kmoll/kg. The specific effective charge of fuel ge on each of modes grows in process of transition from DF to РМР, that is connected to monotonous reduction of the lowest heat of combustion of used binary fuel and some reduction in efficiency of process of combustion. The analysis of results of tests allows to make the following conclusion.

1. The specific effective charge of fuel ge on each of modes grows in process of transition from DF to РМР, that is connected to monotonous reduction of the lowest heat of combustion of used binary fuel and some reduction in efficiency of process of combustion.
2. In process of transition to each of high-speed modes from DF to РМР mass cyclic submission of fuel gц grows, though volumetric cyclic submission Qc (except for modes n = 1600 min^-1, 100 % DF and n =1600 min^-1, 100 % РМР) on each of modes remains practically to a constant.
3. Effective efficiency on each of modes a little (except for mentioned above) changes, factor of surplus of air is practically identical, the temperature of exhaust gases is almost constant.
4. At work on РМР it is marked carbon pollution apertures of sprays of atomizers.
