FAQ: What are the common problems with fuel injectors? Needle body wear

The needle valve body face is subjected to frequent reciprocating motions of the needle valve, and a pit is gradually formed over time, thereby increasing the needle valve lift and affecting the normal operation of the injector.

Solution: The needle body can be grinded on a grinding bed to grind this end face and then ground with a fine abrasive paste on a glass plate.

FAQ: Common problems with injector problems? Injector drops

ERIKC Answer: When the injector is working, the sealing cone surface of the needle valve body will be subject to frequent strong impact of the needle valve, plus high-pressure oil jets continuously from this place, the taper surface will gradually nick or stain, and thus lose the seal , causing the injector to drip. When the temperature of the diesel engine is low, the exhaust pipe emits white smoke, and when the temperature of the engine increases, it becomes black smoke, and the exhaust pipe emits an irregular sound of a shot. If oil supply to the cylinder is stopped at this time, the smoke emission and blasting will disappear.

Solution: The fuel injector can be disassembled, and a small amount of chromic oxide grinding paste (not to be stuck in the needle valve hole) can be disassembled on the needle valve head to grind the cone surface, then washed with diesel oil, and put into the injector test. . If it still fails, replace the needle valve assembly.
