Reasons for excessive fuel consumption of small diesel generator sets

The problem of fuel consumption of diesel generator sets has always been one of the concerns that people are concerned about when purchasing. In addition to the difference in fuel consumption caused by the brand and the use of power, the subsequent wear and tear of the diesel generator set also causes fuel consumption changes:

First, when it is found that diesel generator oil consumption is too high, it should first check the body and gear room cover, wheel side of the big plate, rear cover, cover and other joints whether there is oil leakage. If oil leaks, it should be observed that the gaskets at each joint are intact, and the damaged gaskets must be replaced. If the seal is complete, check the looseness of the connecting screws at each location. Use a wrench to loosen the bolt to the specified torque. If the above parts are normal and the oil leakage is at the rack position, check the oil casing. The main inspection location is on the front side of the oil tank side on the same side as the traveling wheel. Loose screws on the base are used to pull the wheel in the V-belt. A long-term collision with the angle iron on the frame of the protection oil shell is caused, and the oil shell is worn out to form a gap and generate oil leakage.

Second, the normal wear of the diesel generator 's engine over a long period of time, or abnormal wear due to improper maintenance, will cause the cylinder liner of the diesel engine to form a longitudinal pull, and the bore and piston side clearance exceeds the specified value, so that the piston ring The corresponding reduction in support force, there is no net phenomenon of scraping oil. Or because the inner ring in the oil ring distorted the spring to break in the opening position of the oil ring, resulting in the oil is not clean and participate in the combustion, resulting in serious consumption of oil symptoms, manifested as diesel engine start difficulties, the exhaust pipe has obvious blue smoke Severe respirator injection. In addition, the piston should be on the upward side. When the assembly is reversed, the combustion chamber is inverted. Although the start of the diesel generator will not be affected, the loss of the engine oil will be severe. The fuel consumption is about 0.5 kg per day.
