摘要
本文阐述了在一台单缸直喷式柴油机上进行高温冷却模拟隔热试验。在实测气缸盖壁面平均温度、瞬态温度和性能参数的基础上,详细研究和分析了高温冷却对气缸盖壁面传热规律和发动机性能参数的影响。本文证实,适当的高温冷却能够模拟气缸盖壁面喷涂陶瓷的隔热,并可降低柴油机油耗率。
Experiments of high temperature cooling simulating insulation were conducted on a single cylinder DI diesel engine. The effects of high temperature cooling on heat transfer and performance of the engine were investigated and analyzed in detail. The results of the experiments demonstrated that appropriate high temperature cooling can simulate the ceramic insulation and can reduce the engine fuel consumption.
