Injector FAQ
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.
FAQ: Analysis of Common Failures of Fuel Injection Pumps? Oil spill
ERIKC Answer: (1) The oil pump leaks. If the clearance between the plunger and the plunger sleeve is too large, the fuel will leak into the camshaft chamber from the gap to dilute the oil, destroy the lubrication condition of the injection pump, and accelerate the wear of the components. In addition, low-pressure oil leakage can also occur between the pipe joint, the sleeve and the housing.
