柴油出租车燃用麻疯树制生物柴油的试验研究

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

摘要:

对柴油出租车燃用生物柴油体积混合比例分别为10%(简称BD10)和5%(简称BD5)的石化柴油麻疯树制生物柴油混合燃料及柴油(简称BD0)的经济性、排放性、可靠性等进行了试验研究.结果表明：柴油出租车燃用BD10,BD5的排放性能稳定，低于现行国Ⅱ标准规定的排放限值；与BD0比较，柴油出租车燃用BD10的百公里油耗略高，NOx+HC,NOx,CO及颗粒物排放分别降低5.3%,9.1%,15.9%,8.9%；燃用BD5的百公里油耗基本相当，NOx+HC,NOx,CO及颗粒物排放分别降低3.5%,4.9%,1

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.
