在修理195柴油机时,当供油系统出毛病时,一些机手和修理工总是在柱塞和喷油嘴上找问题,甚至把一些尚能使用的喷油嘴、柱塞换掉,而忽视了对出油阀的检查.出油阀偶件在供油中起重要作用,磨损后可以使油嘴滴漏、燃油供给量增加、喷油时间滞后,从而导致发动机难以起动,敲缸,转速不稳,排气冒烟及马力不足等故障. 出油阀是否良好,可用以下力法检查: 1.将出油阀放到试验台上做喷油试验.良好的出油阀喷出的柴油应呈雾状.如果油束呈连续不断的线形,而不是雾状,并有小油滴从油头滴下,即是出油阀损坏.
When repairing the 195 diesel engine, when the fuel system went out of order, some handguns and mechanics always looked for problems on the plungers and injectors, and even neglected some still usable fuel injectors and plungers Oil valve check valve plays an important role in the oil supply, wear can make the nozzle drip, fuel supply increased, the injection time lag, resulting in the engine is difficult to start, knock cylinder, speed instability, Exhaust smoke and horsepower and other failures. Outlet valve is good, the following force method can be used to check: 1. The oil valve on the test bench to do the fuel injection test. Out of a good valve out of diesel fuel should be fog If the oil is continuously continuous linear shape, rather than the mist, and a small drop of oil dripping from the head, that is, the oil valve damage.
