The engine exhaust smoke is individual cylinder fuel injection stop, available by cylinder fuel injection stop method to check, make a cylinder to stop fuel, such as beiben V3 exhaust pipe fittings is no longer black smoke, while the engine is running or minor change, namely that the cylinder nozzle is faulty or single cylinder fuel injection pump oil injection the injection pump is too large, detachable side cover, check the cylinder adjusting gear locking screws are loose, such as intact, then remove the nozzle, connected to the high pressure oil cylinder, and the piston spring seat with a screwdriver to pry, do pumping action, check if the fuel injection nozzle, atomization or atomization a drop of oil or bad phenomenon, should check the decomposition of nozzle, and adjust.

After cylinder inspection, if the injection volume is too large, the governor cover should be opened. Check whether the line of adjusting the gear bar of North Run V3 is moving too much to the fuel injector casing. Meanwhile, check the governor's flying hammer and so on.

If no fault is found in the inspection, the fastening screw of the connecting disk can be loosened and the connecting disc is rotated to delay the injection time. If the black smoke vanishes and the engine does not shake, it shows that the time of the injection is too dry and the time of injection should be checked. If these parts are all good, check the timing screws on the plunger tappet of the North running V3 parts injection pump.
