摘　　要：发动机磨合对提高其动力性、经济性、可靠性及延长使用寿命具有重要意义。通过对冷磨合过程中机械损失的分析,提出了基于冷磨合过程中反拖扭矩变化规律的视情冷磨合规范。结果表明,提出的新规范可提高磨合效率和磨合质量。Running-in is significant for the improvement of power performance, economy, reliability and lifespan of engine. By analyzing the mechanical loss in cold running-in process, the condition- based cold running-in criterion of engine is proposed based on the variation pattern of reverse drive torque. The result of test illustrates that the new cold running-in criterion can raise the efficiency and quality of running-in.
