Experimental Research of Diesel Taxis Fueled by Jatropha-based Biodiesel Blends

Abstract:

An experimental research was made into the diesel taxis on its fuel economy,pollution emission,and reliability performances of 10% and 5% jatropha-based biodiesel blend with conventional diesel (volume ratio,recording as BD10 and BD5 respectively).The experimental result shows that pollution emissions of diesel taxis fueled by BD10 and BD5 are fully complied with current national emission standards.The fuel consumption per 100 kilometers of BD10 fueled diesel taxies is a little higher than that of conventional diesel fueled taxies,and the NOx+HC,NOx,CO and PM emission of BD10 fueled taxies reduces about 5.3%,9.1%,15.9% and 8.9% respectively.Moreover,the fuel consumption per 100 kilometers of BD5 fueled diesel taxies is almost the same with that of conventional diesel fueled taxies,but the NOx+HC,NOx,CO and PM emission of BD5 fueled taxies reduces about 3.5%,4.9%,10.5% and 3.6% respectively.And,the deposit carbon on fuel injector head of biodiesel fueled taxies increases a little,which,however,does not affect the taxi work.
