1, remove the generator200 kw generator 1 cylinder of high pressure tubing, rotate the crankshaft to make 1 cylinder piston in the expansion cycle starting point, the wheel on the pointer on the flywheel shell "0" line. Then reverse diesel engine crankshaft, examine the window of the pointer on the flywheel is equivalent to the Angle of fuel injection advance Angle regulation, then loosen the fuel injection pump drive shaft section and two fastening bolt on the plate, according to the rotation direction of fuel injection pump, slowly and evenly to turn the fuel injection pump camshaft 1 cylinder oil outlet oil level fluctuation of instantaneous just happened so far and screw down the combination plate are the two screws.

2, remove the Stamford generator 1 cylinder of high pressure oil pipe, rotate the crankshaft make 1 cylinder piston compression about 40 o before final position, and then press rotation direction slowly and evenly rotate the crankshaft of diesel engine, at the same time pay close attention to fuel injection pump oil level 1 cylinder oil outlet. It happened when the oil level of volatility, it indicates that the cylinder oil, 1 now examine the pointer to the window on the flywheel scale value is the number of fuel injection advance Angle.

If this Angle is not in conformity with the prescribed scope, can loosen the joint plate two fixed screw, adjust the fuel injection pump camshaft around the required Angle (transmission shaft flange on the scale, each is equivalent to the crankshaft Angle 3 o), advance Angle is too small, the camshaft according to the running direction; Advance Angle is too large, then the running in the opposite direction of rotation, then tighten the joint plate two screws, repeat to check it again, until meet the prescribed scope.

Sometimes, e. differs little, check fuel injection advance Angle and can not loosen the joint plate turn the fuel injection pump camshaft, and as long as the fuel injection pump four mounting screws relax a little, turns the fuel injection pump body be tiny to adjust, its rotation direction should be contrary to the second method, after adjust the screw.
