摘　　要：甲醇燃料是一种绿色、低碳、清洁能源。在自主研发的甲醇增程式发动机(低温起动时采用汽油作为燃料)上进行了GB17691-2018重型柴油车污染物排放限值及测量方法(中国第六阶段)中规定的WHTC排放试验循环测试,通过试验研究起动燃料切换控制策略对PM、PN排放的影响。结果表明:合理的燃料切换,有助于抑制污染物中颗粒物的产生。Methanol is a kind of green,low carbon,clean energy.Based on the independent research and development of methanol range extender engine(starting at low temperature with gasoline fuel),emission test was carried out on WHTC,the emission test cycle stipulated in GB17691-2018.Through the experiment,the influence of the control strategy of starting fuel switching on PM and PN emissions is studied.The results show that the reasonable control strategy of starting fuel switching is helpful to suppress pollutant particulate matter.
