不同供油提前角下地沟油生物柴油-柴油混合燃料的经济性和排放特性试验研究
Experimental study on economic and exhaust emission characteristics of diesel engine fueled with waste cooking oil bio-diesel blended with diesel at different fuel supply advance angle
摘要
Abstract
The experiment of economic and exhaust emission characteristics of diesel engine fueled with 30％ waste cooking oil bio-diesel blended with 70％ diesel at different fuel supply advance angle was conducted.The experimental results show that:the best economic fuel injection timing of B30 Blending fuel was at 18° CA.Increase or decrease fuel supply advance angle,and specific fuel consumption increased.The specific fuel consumption increased by 18％ when fuel supply advance angle was at 18° CA compared with 24° CA at maximum load;With the decrease of the fuel delivery advance angle,NOx emissions reduced,but CO and soot emissions increased to a certain extent; when fuel supply advance angle was at 22° CA,HC emissions was the lowest,with the increase/decrease of fuel delivery advance angle,HC emissions increased,HC emissions increased by 68％ and 50％ when the fuel supply advance angle was at 22° CA and 16° CA,or 18° CA at maximum load respectively.关键词
