What are the countermeasures for the failure of diesel generators?

If there is an obstacle to the lack of cylinders in the diesel generator set, the original lack of cylinder is a common obstacle of the generator set. The focus is on the unstable and vibrating diesel generator, the sound is discontinuous, uneven, weak, easy to extinguish, The exhaust is black smoke and is equipped with an exhaust pipe drip and “oily taste”.
The laborers at the bottom will teach everyone how to check such obstacles: When the diesel generator starts to run at idle speed, touch the exhaust branch pipe of each cylinder by hand. If the temperature of the branch pipe rises slowly, the foot cylinder is not working.

If you suspect that the diesel generator valve is not sealed, you can add a small amount of oil to the cylinder and shake it for a few turns. Then remove the injector and shake the cylinder piston to the top dead center. The piston can be detected from the injector port. The water-free shrinking air pipe head is pressed against the injector port, and the sounding rod is used to resist the inlet and exhaust pipe branches. If there is a “beep” sound, the foot valve is deflated; if the sound of the “hook” is heard, Then shake the crankshaft again and listen again.
If the suspected piston ring is deflated, a little oil can be added to the cylinder from the injector mounting hole to restart. If the labor is normal, it can be proved. If the cylinder of the generator is still abnormal, and the black smoke of the exhaust or the dripping of the exhaust pipe is tight, and the oil surface of the generator is added, the fuel injector of the generator set has an obstacle.
If you open the water tank cover and see bubbles in the radiator, perhaps there is sound in the crankcase, and the foot cylinder block burns. If the above diagnosis has no problem to be solved, it should be further checked whether the shrinkage ratio of the cylinder is not equal, and whether there are other machine problems such as bending of the connecting rod.
