Causes of injector fuel consumption

The use of diesel generator sets, some customers reflect the phenomenon that the unit appears too fast oil consumption, but do not know exactly which parts to start from to deal with, the following Fengde will analyze several situations:

First, when the oil consumption is found to be too much, it should be the first to check whether there is oil leakage of the body and the gear room cover, the row of wheel side of the large plate, the rear cover, cover cover cover and other connections. If there is oil leakage, attention should be paid to observe whether the sealing gasket of each connection part is complete, and the damaged sealing gasket should be replaced. If the gasket is complete, you should pick up and check whether the connection screws of each part are loose. Loose bolts with a wrench to the specified torque can be. If the above parts are basically normal, and oil leakage in the rack position, the oil shell should be checked, the main check parts in the same side of the oil shell with the wheel side of the front, mostly due to the loosening of the seat screws, the traveling wheel in the triangle belt pulling with the protection of the oil shell of the rack under the corner of the angle iron produces long-term abrasion, the oil shell grinding through the formation of a gap and oil leakage.

Second, the engine formed by long-term use of normal wear and tear, or due to improper maintenance of the formation of abnormal wear and tear, will make the diesel engine cylinder liner to form longitudinal pull marks, cylinder diameter, piston side clearance exceeds the prescribed value, so that the piston ring of the corresponding reduction in the bracing force, scraping the phenomenon of oil is not clean. Or because the oil ring within the inner support of the twisted spring disconnected in the oil ring opening position, resulting in scraping oil is not clean and involved in combustion, resulting in serious oil consumption symptoms, manifested in the diesel engine starting difficulties, the exhaust pipe there is obvious blue smoke, respiratory oil spraying serious. Furthermore, the piston should be up the side, in the assembly due to the direction of the inverted combustion chamber to form an inverted state, although it does not affect the diesel engine start, but the loss of oil will be quite serious, the daily oil consumption of about 0.5 kilograms.

Third, the valve guide wear serious will also burn diesel generator set oil situation is rare, but according to the introduction of the relevant information, is not to be taken lightly a reason.
