This paper discusses the influence of the biodiesel obtained from grape seeds oil, palm oil and sunflower oil on the energetic performances and combustion process of a Diesel engine. In this study pure diesel fuel and two concentrations (6 % and 10 %) of blends with biofuels were used for experimentally tests on a Renault K9K diesel engine. During experimental tests were observed: engine power, cylinder pressure, heat release and the amount of CO2 emissions. The results obtained with biodiesel are compared with the results obtained with pure diesel fuel. Better oxidation of the biofuels induces a better combustion in cylinder and more CO2 emissions. The CO2 emissions are either influence by the lower carbon content of biofuels. The results of this study sustain that using 6 % and 10 % of blended biofuels with diesel fuel decrease the pollutant emissions of the diesel engine. Deviations between experimental and the simulation results confirm the validity of the mathematical model adopted for the simulation.
