How to Adjust The Fuel Supply Advance Angle of Diesel Engine?

During the operation of the diesel generator, the upper part of the cylinder can clearly hear a crisp knocking sound of the piston hitting the cylinder block, which is often referred to as "knocking the cylinder". The reason for the occurrence of "knocking" is that the fuel supply advance angle of the diesel engine is too small. How to adjust the fuel supply advance angle of the diesel engine? There are various methods, and now we will mainly introduce the simpler one. The specific steps are:

(1) Connect the high and low pressure fuel pipes, place the throttle control lever in the maximum fuel supply position, and use a hand pump to supply fuel to remove air from the fuel system.

(2) Remove the high-pressure oil pipe of the first cylinder and install the timing pipe.

(3) Rotate the crankshaft clockwise to remove air from the timing tube. When shaking the timing tube, some fuel flows out, making the liquid level in the oil pipe clear. Then slowly rotate the crankshaft while observing the oil level in the tube. At the moment when the oil level rises, immediately stop rotating the crankshaft and mark a notch on the outer surface of the crankshaft pulley against the gear housing cover.

(4) Continue to rotate the crankshaft clockwise until the mark on the crankshaft pulley is aligned with the mark on the gear housing cover, and stop turning (at this point, the piston is at the top dead center of cylinder 1 compression).

(5) Measure the arc length of the piston on the pulley between the top dead center of one cylinder compression and the pulley line, and calculate the fuel supply advance angle of the diesel engine at this time.

(6) Calculate the difference between the measured fuel supply advance angle and the specified advance angle, loosen the fastening bolts of the fuel injection pump, rotate the camshaft of the fuel injection pump clockwise, and finally tighten the bolts.

When the injection advance angle of the diesel generator diesel engine is correct, the sound will be eliminated, and the diesel engine can work normally, giving play to its original working efficiency. I believe that after the brief introduction of Starlight Power, you will have a better understanding of the diesel generator set.
