Abstract

The fuel economy and pollutant emissions characters of diesel taxies in Shanghai were analyzed. In particular, the fuel consumption and fuel cost per 100 kilometers, turnover, traveled distance, service kilometers, empty-loaded rate, and CO, NOX, HC+NOX, PM emissions characteristics of diesel taxies were carried out. The analysis result shown that compared with gasoline taxies, the fuel consumption and fuel cost per 100 kilometers of diesel taxies were reduced by 29% and 26% respectively. Diesel taxies will get more traveled distance, further service kilometers, and added turnover, whereas lower empty-loaded rate and less fuel cost per 100 kilometers. Among the total 120,000 kilometers test distance, the CO emission of diesel taxies was lower than the limited value of China national emission standard IV, the NOX and HC+NOX emission is under the limited value of China national emission standard III, whereas, the PM emission was under the limited value of China national emission standard II. All of CO, NOX, HC+NOX, and PM emissions of diesel taxies were reduced obviously when fuel by Shanghai IV diesel after 1st November, 2009.

上海市柴油车燃油经济性及污染物排放分析

分析了上海市柴油车的燃油经济性和污染物排放特征。特别是柴油车的油耗和百公里燃油成本、周转量、行驶里程、服务公里数、空载率以及CO、NOX、HC+NOX、PM排放特征。分析结果表明，与汽油出租车相比，柴油出租车百公里油耗和百公里燃油成本分别降低29%和26%。柴油出租车的行驶距离更长，服务公里数更长，周转率更高，空载率更低，百公里燃油成本更低。在12万公里的总测试里程中，柴油车的CO排放量低于中国国家排放标准IV的限值，NOX和HC+NOX排放低于中国国家排放标准III的限值，而PM排放低于中国国家排放标准II的限值。2009年11月1日以后，柴油出租车改用上海四号柴油后，其CO、NOX、HC+NOX和PM排放均明显减少。
