摘要
编制了欧Ⅲ标准常温下"冷起动后排气排放试验"程序,在某型号汽油发动机的各种稳态工况下,测得不同点火提前角和空燃比条件下运行时尾气中的一氧化碳(CO)、碳氢化合物(HC)、氮氧化物(NOx)的排放特性。通过试验分析了各种运转参数对汽油机尾气排放特性的影响关系,为综合匹配各运转参数来达到降低车用汽油发动机尾气排放奠定了基础。
The ＂Cold start exhaust emission test＂ program is compiled according to Euro III at normal temperature. The emission characteristics of a specific type gasoline engine under various steady operating conditions are obtained at different ignition advance angles and air fuel ratios, e.g. tail gas emissions of CO, HC and NOx. Various operating parameters of emission are studied and analyzed with the assistance of tests so as to lay the foundation for further study on reduction of exhaust emission of vehicle gaso- line engines.
