摘要
采用高速CCD数码相机对超多喷孔喷油嘴以及传统喷油嘴的喷雾进行拍摄分析,发现超多喷孔喷油嘴的上下两层喷雾束,在离开喷孔后不久就相互碰撞,与传统喷油嘴相比其喷雾贯穿距离要短、单束喷雾锥角要大,这些特性有利于柴油机组织缸内预混合燃烧。
The fuel sprays of UMH（ultra-multi-hole） and conventional nozzle were grabbed by high speed CCD digital camera. The results show that two sprays of upper and lower-layer of UMH nozzle impinge after injeeted from hole shortly. The UMH nozzle has shorter penetration and bigger single-spray angle than those of eonventional nozzle. These eharaeteristies are useful to form the premixed eombustion of diesel engines.
