摘　　要：在两台采用浅ω型燃烧系统的高速柴油机上，对延迟供油的燃油消耗率、最高燃烧压力、NOx排放与排气烟度的影响进行了试验研究，并依据实测示功图采用现象学燃烧模型推求燃烧率与NOx生成，据此对试验结果作出理论解释。A experimental investigation of the influences of fuel injection timing delay on fuel consumption, peak combustion pressure, NOx emission and exhaust smoke are carried out on two engines with shallow co combustion system. According to the measured indicator diagram, combustion rate and NOx emission formation are predicted by using phenomenblogical combustion model.Furthermore, theoretical explanations can be made for the test results.
