Abstract:
The work presents the testing results concerning the operation of agricultural tractors which
were divided into two groups: those operating on diesel fuel and others on biofuel B20. The use of biofuel led to
obtain performance characteristics in the case of Diesel engines during a seasonal year beginning with the
plowing and ending with the harvesting works. The data presented in this paper, such as: oil consumption when
combustion takes place, gases escaped into the crankcase, compression in cylinders etc., proved a good
functioning as in the case of tractors operating on diesel fuel.
