摘要
对柴油车微粒捕捉器的各种再生控制方法进行了比较分析 ,并对背压控制方法进行了试验研究。利用背压模拟装置替代微粒捕捉器 ,研究了排气背压对 YC6 10 8柴油机的动力性、燃油经济性、排放和排温等参数的影响 ,在此基础上讨论了微粒捕捉器定背压再生控制方法的可行性及控制限值。首次提出利用排气温度对背压控制方法进行修正 。
Several methods for regeneration control of diesel particulate trap are analyzed in this paper.Based on the analysis,the backpressure control method is selected for experimental study.A backpressure simulation device is established to substitute the diesel trap.Influence of backpressure on several parameters of YC6108 engine,such as diesel power,fuel consumption,emission and exhaust temperature,are studied.The constant backpressure control strategy and the backpressure limitation are discussed based on the experiments.The temperature correction for backpressure is discussed for the first time.The correction guarantees the correct trap regeneration time and is necessary for practical control.
