柴油机预燃室喷嘴的热负荷研究

Study on the Thermal Load of the Precombustion Chamber Nozzle in the Diesel Engine

本文提出了一种研究柴油机预燃室喷嘴热负荷的方法。将其应用于重１２１８０ＣａＤ－２喷嘴热负荷分析，得出了有效降低热负荷的改进措施。台架测试结果证实了计算方法的可信性。

A method for studying the thermal load of the precombustion chamber nozzle in the diesel engine is proposed.By this method the thermal load of the 12180CaD 2 nozzle is analyzed and some inprovement is reached which can decrease its thermal load effectively. Measuring results on the diesel engine verified the credibility of this theoretical method.
