一、这样的回油管需要改进我们下乡检查机务工作时,发现有的机手把S195型柴油机喷油器的回油管直接接到柴油细滤器上,这样改进的回油管路显得紧凑、牢固,也达到了节油的目的。殊不知,随着柴油机使用时间的延长以及喷油器针阀与阀体的磨损、拉伤,喷油器喷油前,气缸内的压缩空气先经喷油器、回油管进入柴油细滤器及输油管路中,导致柴油机的燃油路有空气,影响柴油机的正常工作。经验不多的机手对这种故障判断不清,还会造成乱拆乱卸柴油机,盲目更换零件,浪费尤甚。很明显,这种改装结构尚欠佳。为达到节油目的,又不致发生上述故障,我们也改进了喷油器的回 First, such a return pipe needs to be improved When we went to the countryside to inspect the maintenance work, we found that some engineered S195 diesel engine oil return pipe directly connected to the diesel fine filter, so that the improved return line appears compact and solid, Also achieved the purpose of fuel-efficient. As everyone knows, with the extended use of diesel engines and injector needle and body wear and tear, the fuel injector before the cylinder of compressed air through the injector, the return pipe into the fine filter and the oil pipe Road, leading to the diesel engine fuel air, affecting the normal work of the diesel engine. Less experienced hands on this fault judgment is not clear, but also cause disorganization dismantling diesel engine, blind replacement parts, waste more. Obviously, this modified structure is still not good. In order to achieve the purpose of fuel-saving, but also does not occur above the failure, we also improved the injector back
