针对影响涡流室柴油机冷起动性能的因素及涡流燃烧室最佳结构参数匹配问题,采用5种燃烧室设计方案进行了对比试验,得到了0℃左右冷起动时合理设计的涡流室副燃烧室形状和尺寸、通道的形状与位置、起动孔的锥度与夹角、主燃烧室活塞顶导流槽的形状等参数;将各项性能较优的方案1和方案2应用于165F柴油机,结果表明,在-2℃的低温下能使其顺利起动,且性能指标得到了改善,达到了预期的效果。
In view of the factors that affect the cold starting performance of the vortex chamber diesel engine and the matching of the optimal structure parameters of the vortex combustor, five kinds of combustion chamber design schemes were compared and the shape of the auxiliary chamber of the vortex chamber And the size, the shape and position of the channel, the taper and angle of the starting hole, the shape of the top of the main combustion chamber and the shape of the diversion channel of the main combustion chamber. The best performance of the program 1 and 2 are applied to the 165F diesel engine, At -2 ℃ low temperature can make it smooth start, and the performance index has been improved to achieve the desired results.
