What are the factors that affect the fuel consumption of self-start diesel generators?
Many users are wondering why the self-starting diesel generating set has gradually increased fuel consumption during its use. The detection of diesel generator set has not found any problems, and no specific reasons can be found in the inspection. What are the factors that affect the self-start? What is the fuel consumption of diesel generators?
1. Check if the seals on the joints of the engine body and the gear chamber cover, the big wheel on the side of the wheel, the back cover, the cover, etc. are not in good condition, and the screws at the joints are not loosened. If there is oil leakage at the rack position, the oil casing must be inspected to check the front of the oil casing on the same side as the traveling wheel. This is generally because the seat screw is loose, causing the wheel to pull under the V-belt and protect the oil casing. The long-term impact of iron in the rack angle creates gaps that cause oil leakage.
2. Worn engine valve duct leads to extra oil loss of the unit.
3. The engine wear causes the cylinder liner of the diesel engine to form a longitudinal pull mark. The cylinder bore and the piston side clearance exceed the specified value, which leads to a corresponding decrease in the supporting force of the piston ring, and a phenomenon that the scraping oil is not clean. Or because the internal support twisting spring in the oil ring is disconnected, so that the scraping oil does not participate in the combustion, which makes the diesel engine start difficult, the exhaust pipe emits blue smoke, and the respirator fuel injection is serious, causing additional consumption of oil.
During the use of the self-starting diesel generating set, the oil generally passes through the gap between the piston ring and the ring groove, and the gap between the valve and the tube enters the combustion chamber. The direct reason for its penetration is that the first piston ring is in the vicinity of top dead center due to a sharp drop in its movement speed, and it throws the lubricant attached to it into the combustion chamber. Therefore, the matching gap between the piston ring and the piston, the oil scraping and oil scraping capacity of the piston ring, the pressure in the combustion chamber and the viscosity of the oil are closely related to the oil consumption. If you find that the fuel consumption is large, the following inspections are generally performed to find out where the problem is and to solve the problem quickly.
