1.一台S195柴油机更换活塞连杆组后,起动冒黑烟。令人奇怪的是,在修理机器时已对喷油雾化程度、配气相位等进行了调整。为什么还发生此种故障呢?拆检时发现未将活塞顶部涡流坑的“桃尖”对准喷油器的方向,而错误地转向相反方向。及时纠正后,故障排除了。S195柴油机燃烧室为涡流式燃烧室,混合气体在涡流室中经过第一次混合,然后以一定的角度经过主喷孔喷出,在活塞顶部的导流下,使燃油与空气再进行第二次混合,这样燃油就能充分燃烧,不冒黑烟。 2.一机手在安装S195柴油机飞
1. A S195 diesel engine replacement piston rod set, start black smoke. Curiously, the level of spray atomization, gas phase, etc. has been adjusted while the machine is being repaired. Why did such a fault occur? When disassembling, it was found that the top of the piston whirlpool pit “peach tip ” is not aligned with the direction of the injector, and erroneously turned in the opposite direction. Timely corrected, troubleshooting. The S195 diesel engine combustor is a vortex combustor. The mixture is first mixed in the vortex chamber and then ejected at a certain angle through the main orifice. Under the flow diversion at the top of the piston, the fuel and air are again subjected to the second Mix times so that the fuel will burn well without black smoke. 2.
