Cummins diesel generator manufacturers analyze the reasons for the rapid fuel consumption of diesel generator sets. The details are as follows:
1. When it is found that the oil consumption is too much, you should first check whether there is oil leakage at the connections between the body and the gear chamber cover, the large plate on the side of the running wheel, the rear cover, and the cover. In case of oil leakage, pay attention to observe whether the sealing gasket of each connection part is complete, and replace the damaged gasket. If the gasket is complete, check whether the connecting screws of each part are loose. Use a wrench to tighten the loose bolts to the specified torque. If the above parts are basically normal, and the oil leakage is at the position of the frame, the oil casing should be checked. The main inspection part is at the front end of the oil casing side on the same side as the travel wheel. Mostly because the screws of the machine base are loose, the travel wheel is pulled by the V-belt. The bottom and the frame angle iron that protects the oil casing produce long-term friction, and the oil casing is worn through to form a gap and oil leakage occurs.
2. The normal wear caused by the long-term use of the engine, or the abnormal wear caused by improper maintenance, will cause longitudinal pull marks on the cylinder liner of the diesel engine. The clearance of the cylinder diameter and piston side exceeds the specified value, so that the supporting force of the piston ring will be reduced accordingly. Small, the phenomenon of oil scraping is not clean. Or because the inner support torsion spring in the oil ring is disconnected at the opening of the oil ring, the oil scraping is not clean and participates in the combustion, resulting in serious oil consumption symptoms, which is manifested as difficulty in starting the diesel engine and obvious blue smoke coming out of the exhaust pipe. , the respirator has serious fuel injection. In addition, the side of the piston that should be upwards is in an upside-down state due to the inversion of the direction during assembly. Although it will not affect the starting of the diesel engine, the loss of oil will be quite serious, and the fuel consumption is about 0.5 kg per day.

The above are the reasons that cause the diesel generator set to consume too much fuel.
