重型直喷柴油机缩口燃烧室结构特点与评价 - Finally , the inlet port and combustion chamber designed and machined is tested on 4100qb . the paper mostly investigates the change of performance targets of the engine that three different grooved chambers including two different re - entrant model and one w model match with various intake port and nozzles , in order to realize the influence of chamber geometry on combustion process . the results analyzed have indicated that re - entrant grooved chambers can enhance the turbulent intension in the chamber , improve the combustion proces of diesel engine on the altiplano , being groove , re - entrant and convex , and have the farther developing potential
着重研究两种缩口、一种直口矩形环槽燃烧室与不同进气道、喷油嘴的组合方案发动机的动力性、经济性及排放指标的变化,确定燃烧室的几何形状对燃烧过程的影响。分析结果表明,由于有矩形环槽、燃烧室缩口以及燃烧室底部凸台,缩口矩形环槽燃烧室中的紊流得以加强,改善了高原柴油机的燃烧过程,这种燃烧室有进一步发展的潜力。
