液化石油气汽车尾气减排的研究与试验

RESEARCH AND TESTING ON EMISSION REDUCTION OF LPG VEHICLES

为了减少机动车的尾气污染物排放,中国大、中城市大力推广使用燃气公共汽车和出租车,燃气汽车尾气污染物排放对城市环境影响,如何减少燃气汽车的尾气排放是目前面临的一个新课题。采用在燃气汽车燃料中加注适量的CPG-4型增效剂的方法进行对比实验研究,通过改善其燃烧特性,达到燃气汽车节能减排的目的。试验表明,在燃气汽车燃料中加注适量的CPG-4型增效剂能节约燃气消耗6%左右,大幅减少HC和PM的排放。

In order to reduce the emission of the exhaust gases by the vehicles,buses and taxies are advocated to prevalently to use LPG in Chinese big and medium-sized cities,where the influence of the exhaust pollutants by the LPG vehicles on the city's environment exists. Accordingly,how to reduce the emission of the vehicles is a brandnew subject yet to be addressed. Aiming at this task,it was made a comparative experimental research on the vehicles through adding a proper amount of CPG-4 synergist to the fuel of the LPG vehicles so as to ameliorate their combustion performance to reach the purpose of energy conservation and emission reduction. The experiments demonstrated that the LPG could be saved by approximately 6% and the emission of HC and PM was also greatly reduced by adding a proper amount of CPG-4 synergist to the fuels of the LPG vehicles.
