缝隙孔式喷油嘴偶件燃油喷注雾化形态的研究

Research on Atomization Patterns for Cracks Hole Style Fuel Injection Nozzles

采用高速照相机对缝隙孔式喷油嘴偶件以及传统孔式喷油嘴偶件的喷注形态进行拍摄分析,发现缝隙孔式喷油嘴偶件由于喷孔为缝隙孔,喷注能形成更广的蒸汽区域,这些特点更有利于柴油机组织缸内的混合燃烧。

Shoot analysis of injection patterns between cracks hole style fuel injection nozzles and traditional stem hole style fuel injection nozzles by high speed cameras, cracks hole style injection nozzles can create a wider range of oil steam area, these features can have more conducive for a mixed burning in diesel cylinders.
