1, the first check the car to find a clean block of wood, hands to wash, drive the fuel pump below (ie, upright), with your fingers stick some clean diesel, dripped into the pump oil into the screw hole, Pump) or lugs (I pump) purposefully fixed in the stop position, the maximum fuel supply position, grasp the pump with both hands, push down the force, rebound rise and then depressed, so repeated several times, with this At the same time pay attention to observe the oil valve tight seat oil situation: 1.1 in the stop position, push down, the valve seat should not be out of oil: 1.2 in the maximum fuel supply position, push down, the valve is tight Block should be the most fuel injection. If you can meet the above requirements, then the assembly is complete. Otherwise it should be reassembled until it meets the requirements. 2, the car inspection method will be equipped with a good injection pump (together with the adjustment of the fuel supply advance angle adjustment pad), mounted on the side of the gear chamber cover (to be sure to ensure that the call set or lugs into the oil dial inserted) , Fix the connection screw, connect the oil pipe and deflate, purposefully fix the throttle at different positions (ie stop oil level and maximum oil level), open the depressurization and observe the following three situations A kind of oil situation: 2.1 not connected to high-pressure tubing, the other person directly observed the oil valve seat of the oil situation. 2.2 connected to the high-pressure tubing, not connected to the injector, and the high-pressure tubing outlet up, observe the oil outlet situation. 2.3 connected to the high-pressure tubing, and connected to the injector, injector fuel injection directly observed. As long as the throttle is in the stop position, none of the above three oil, and the throttle at the maximum fuel supply position, the maximum output, it shows that the fuel injection pump assembly intact, otherwise it should be reassembled open until meet the requirements. In practical work, we must make flexible use of the above two kinds of inspection methods. The first method to prioritize, used to check the newly assembled monomer pump, if the assembly does not meet the requirements, can be directly open to check the correction, but this method is completely manual operation, more laborious: The second method is very close The actual work of the diesel engine, after passing the first method of inspection, for those who are not skilled, and then check the confirmation of this method, the heart is even more count, and can avoid the single pump due to the pin or lug Set into the oil dial inserted in the start after the "speed" phenomenon.
