Reasons for Excessive Fuel Consumption of Cummins Generator Sets

Today we will give you a brief introduction about what causes the excessive fuel consumption of Cummins generator sets. What else do you need to know about this, welcome everyone to visit our Dingbo website. And then we will introduce the related content to you.

Normal wear caused by long-term use of the engine, or abnormal wear caused by improper maintenance, will cause the cylinder liner of the diesel engine to form longitudinal draw marks, and the cylinder diameter and piston side clearance will exceed the specified value, which will reduce the supporting force of the piston ring. There is a phenomenon of dirty oil scraping. Or because the internal support twisting spring in the oil ring is disconnected at the opening position of the oil ring, the oil scraping is not clean and participates in the combustion, causing severe oil consumption symptoms, manifested as the diesel engine is difficult to start, and the exhaust pipe has obvious blue smoke. , The respirator is spraying severely. Furthermore, the piston should be on the upward side, and the combustion chamber is turned upside down during assembly. Although it will not affect the start of the diesel engine, the oil loss will be quite serious, with a daily fuel consumption of about 0.5 kg.

When it is found that the engine oil is consumed too much, first check whether there is oil leakage at the connection between the body and the gear chamber cover, the large plate on the side of the wheel, the rear cover, the cover and so on. In case of oil leakage, pay attention to observe whether the gaskets at each connection part are intact, and replace the damaged gaskets. If the gasket is intact, check whether the connecting screws of each part are loose. For loose bolts, use a wrench to reach the specified torque. If the above parts are basically normal and the oil leakage is in the position of the frame, the oil shell should be inspected. The main inspection part is the front end of the oil shell side on the same side as the traveling wheel. Mostly because of the loosening of the screw on the frame, the traveling wheel is pulled by the triangle belt. Long-term friction with the frame angle iron protecting the oil shell will cause the oil shell to grind through to form a gap and cause oil leakage.
