引言 由于燃料在柴油机燃烧室內的物理化学过程目前还沒有完全掌握,因此近年来虽已积累多关于这方面的試驗研究資料,例如:利用摄影对燃烧过程的研究;燃烧室气运动的研究;噴油射綫方向对工程的影响以及燃烧室在柴油机上的經驗等等,但确定新設計柴油烧室的合适参数仍需經过具体的試驗。 Introduction Since the physical and chemical processes of fuel in the combustion chamber of diesel engine are not fully understood at present, many experimental research materials have been accumulated in recent years, such as the research of combustion process by photography, the research of gas movement in combustion chamber, The influence of the direction of the oil ray on the project, the experience of the combustion chamber on the diesel engine, etc. However, the specific parameters for determining the newly designed diesel combustion chamber still need to be concretely tested.
