For　improving　bad　emissions　resulted　from　frequently　stop/re-start　of　bybrid　electric　vehicle　(HEV)　engines　in　urban　drive　condition,　using　methanol　as　the　fuel　of　HEV　engine　in　quick　start　was　proposed　and　experimentally　studied.　The　experimental　engine　was　a　spark　ignited　port　fuel　injected　gasoline　engine.　An　AC　motor　was　connected　to　the　flywheel　to　simulate　quick　start　process　of　HEV　engine.　A　self-developed　electric　control　unit　was　used　to　control　the　experimental　system.　Results　show　that　comparing　with　gasoline　engine,　methanol　engine　consumes　less　energy　in　quick　start,　both　the　CA0-10　and　CA10-90　are　decreased,　and　the　HC,　CO　and　NOx　emissions　are　reduced　significantly.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
