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。
In this paper, based on the design and experiment of the ω-shaped combustion chamber with four corners, the influence of turbulence disturbance on the combustion process is expounded. It is pointed out that the use of turbulent motion in the combustion chamber design, attention to the appropriate combination of the combustion chamber, intake vortex and fuel injection laws can be achieved while keeping the economy of the small direct injection diesel engine low and reducing the harmful components in the emissions.
