Emission characteristics of turbo-charge diesel engine with bio-diesel fuel

Comparative tests were made on a turbo-charge diesel engine fueled by bio-diesel and ordinary diesel separately in terms of the output power, fuel consumption and emission characteristics. The results show that the influence of bio-diesel fuel on the engine output power is less than 5% when the injection pump is the same without change. The diesel engine exhaust smoke, FT, CO and HC emission could be reduced greatly when bio-diesel fuel is burnt, but the NO_x emission could be increased. The shortcoming of the bio-diesel fuel could be overcome through a proper delay of the injecting timing. The bio-diesel fuel is an ideal recycling clean fuel.
