Summary:

The use of biomass fuels such as biodiesel as an alternativefuel for petroleum diesel in automotive sector is of greatimportance today, as it reduces global warming. Previous researchhas pointed out that biodiesel/diesel blends can be used in dieselengines with little or no modification. It is estimated that thedifferences on the characteristics of diesel engines exhaustemissions are due to the different molecule composition ofconventional diesel and biodiesel fuels.The scope of this work was to compare the exhaust gas emissionsfrom the use of mixtures of biodiesel and diesel and their effecton the performance of a passenger car engine. The blends B10, B50and neat biodiesel, B100, were used in an old technology 1600 ccdiesel car, equipped with a retrofit catalytic diesel particulatefilter. While the car was running on a chassis dynamometer withwide open throttle and under full engine load, measurements oftorque, speed and fuel consumption were taken for three differentvehicle speeds and gear ratios. Regarding the emissions, theconcentrations in the exhaust gases of CO₂, CO, HC, NOX and sootopacity values were recorded. The results clearly showed thatincreasing the percentage of biodiesel in the fuel, adverselyaffected the emissions of NOX as compared with neat biodiesel.Diesel engines always run "lean," thus the emissions ofCO and HC were very low and practically negligible. On the otherhand, CO₂ emissions primarily depend on the raw materials and theprocesses that are used for the production of biodiesel. Sootemissions decreased when blends with higher biodiesel content wereused. The engine performance, as measured on the chassisdynamometer, increased slightly by the use of B10, B50 and B100fuels. On average, the torque increased by 4.6% and the power by3.1%, but these results were obtained along with an 11.5% higherfuel consumption. The best overall results, at all speeds, wereobtained using the B100 fuel, with a remarkable average reductionof 26% in soot emission
