对缸内直喷汽油车燃用M15甲醇汽油和汽油的非法规排放进行了对比研究,测试工况包含法规工况和模拟北京市交通状况的3种非法规工况。结果表明:对每一种燃油,法规工况下热起动时排放的醛酮总量、主要醛酮污染物和挥发性有机物中的BTEX(苯、甲苯、乙苯和二甲苯)总量比冷起动下排放的低;在每种工况下,燃用M15甲醇汽油的甲醛排放量比燃用汽油时的高;4种工况中,快速工况热起动状态下醛酮总量、主要醛酮污染物、甲醛和BTEX总量的排放最低。

A comparative study on unregulated emissions from a direct injection gasoline vehicle fueled with gasoline and M15 methanol-gasoline is conducted. Test cycles include a regulated cycle and three unregulated cy-cles simulating traffic conditions in Beijing. The results show that for each fuel, emissions of total aldehydes and ke-tones, major aldehydes and ketones and total BTEX ( Benzene, Toluene, Ethylbenzene and Xylenes) over regulated cycle at hot start mode are lower than those at cold start mode. For each test cycle, formaldehyde emission with M15 is higher than that with gasoline. Emissions of total aldehydes and ketones, major aldehydes and ketones, formalde-hyde and total BTEX with high speed cycle are the lowest among the four cycles at hot start mode.
