摘要
本文在缩口四角ω形燃烧室的设计及试验的基础上,阐述了紊流扰动对燃烧过程的影响。指出在燃烧室设计中运用紊流运动,注意燃烧室、进气涡流与喷油规律恰当的配合,在保持小型直喷式柴油机经济性好的同时降低排放中的有害成份是可以做到的。
Based on the design of contracted lip square toroidal combustion chamber and the experiments with it, the influence of turbulence on the combustion process is expounded. It is also pointed out that, with the pro- per copulation of turbulent flow, combustion chamber, intake swirl and fuel injection rate, it is possible for the small direct injection diesel engine to decrease its toxic emission with its economical property kept desirable.
