柴油出租车燃用不同替代燃料的试验研究

Experimental Research of Diesel Taxis Fueled by Diesel and Its Alternative Fuels

对柴油出租车燃用柴油(BD0),柴油—废弃油脂制生物柴油混合燃料(BD10)和天然气制合成油(G100)的经济性、排放性及可靠性能进行了试验研究.结果表明:与燃用BD0比较,柴油出租车燃用BD10和G100的百公里油耗略高;燃用BD10的CO和颗粒物(PM)排放分别降低17%和9%,NOx和HC+NOx排放分别升高12%及8%;燃用G100的CO,NOx,HC+NOx,PM排放分别降低75%,9%,10%和51%;柴油出租车燃用BD10,G100后,其喷油器头部积炭略有增加,但不影响柴油出租车的正常使用.

Experimental research was carried out on fuel economy, pollution emission, and reliability performances of diesel （BD0）, wasted oil-based biodiesel blend （BD10）, which is the mixture of diesel and waste oil-based biodiesel by 10% volume ratio of biodiesel, and gas-to-liquids （G100） fueled diesel taxies. The experimental results show that the fuel consumption per 100 kilometers of BD10 and G100 fueled diesel taxies is a little higher than that of taxies fueled with BD0, the CO and particle matter （PM） emission of BD10 fueled taxies reduces about 17% and 9%, whereas the NOx and HC＋NOx emission of BD10 fueled taxies increases about 12% and 8% respectively. Moreover, the CO, NOx, HC＋NOx, and PM emission of G100 fueled taxies reduces about 75%, 9%, 10% and 51% respectively. And, the deposit carbon on fuel injector head of BD10 and G100 fueled taxies increases a little, which doesn＇t bring any effect on taxi operation.
