Oil crisis and sharp increase of oil and petroleum market prices, resource limitation fastened the search for alternative energy sources. Among alternative energy sources renewable and especially received from vegetable biomass (fuel alcohol, vegetable oils) are of the greatest interest. With the account of this the article gives the results of studying the peculiarities of the bio-Diesel operational cycle and possibilities to adapt existing Diesels to biofuel. It has been determined that substitution of the Diesel fuel (DF) with rape-seed oil (RSO) and biofuel increases maximal and intermediate injection pressure, earlier start and greater injection duration, loss in frequency and oscillatory amplitude in the pressure pipeline after completing the injection. When RSO is used there appear increased inside lacquer film on the blowgun; which results in the needle valve immobility down to hanging up; needle valve immobility leads to the time lag of inlet and lengthening of the injection, increase in maximal injection pressure. There is quality loss of spraying the fuel, increase in non-uniformity and medium volume diameter of fuel drops, as well as penetration of the fuel jet into the air medium. Higher viscosity of the biofuel increases the injection rate due to leakage decrease in plunger pairs of diesel fuel injection pumps (DFIP).
