摘　　要：通过试验研究了起动结束标志转速、起动油量、环境温度等因素对电控柴油机起动性能的影响。试验结果表明:起动油量脉谱油量一定,稳定运转阶段的HC排放的峰值随着起动结束标志转速的提高而增加,但起动时间不变;HC排放的峰值产生在稳定运转阶段的峰值转速区,暖机阶段的HC排放与起动油量脉谱油量无关。The effects of the start end symbol rotating speed, the quantity of the fuel supply, and the ambient temperature on the start behavior of an electronically controlled diesel engine were studied experimentally. The results show that when the fuel supply map of engine start process is fixed, the peak value of the HC emission during the stablized operating phase of the start process increases with the increase of the start end symbol rotating speed, but the start time is constant. The peak value of the HC emission occurs near the highest engine speed during the stablized operating phase. The HC emission during the warm-up phase of the start process is independent of the start fuel supply map.
