Small details to ensure full combustion of diesel generator set fuel

Engine oil is the most important consumable to ensure the life of diesel generator sets and the safety of components. Therefore, daily attention to oil is an indispensable requirement to ensure the normal operation of generator sets. Therefore, Quark motors should pay attention to the following points of oil:
Keep the best oil supply angle to ensure that the machine does not leak oil.
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 of each connection part are complete, 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 angle iron of the frame that protects the oil shell will cause the oil shell to grind through to form a gap and cause oil leakage.
2. Purify the oil before use and pay attention to the daily maintenance of the engine.
Normal wear caused by long-term use of the engine, or abnormal wear caused by improper maintenance, will cause longitudinal pull marks on the cylinder liner of the diesel generator, and the cylinder diameter and piston side clearance will exceed the specified value, which will reduce the supporting force of the piston ring. Small, the phenomenon of oil scraping appears.
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 sprays severely.
Furthermore, the piston should be on the upward side. 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 daily fuel consumption of about 0.5 kg.
Although it is rare that the valve guide will burn diesel generator oil if it is worn out, it is also a reason not to be underestimated according to relevant information.
3. Increase the temperature of the cooling water of the diesel generator set, and operate the generator set more reasonably.
Try to make the fuel of the diesel generator set fully burned, that is, the use power of the diesel generator set reaches 80% of the output power of the generator set. Control the fuel injection pump to ensure that the fuel supply of the fuel injection pump is not too large. Control the oil in the governor to prevent the fuel supply from increasing, otherwise it will cause the generator set to "runaway".
In addition, we must pay great attention to the smoke phenomenon of the generator set. If the generator set emits dark smoke or black smoke, these indicate that the diesel generator set is working abnormally and must be checked and dealt with in time. Only keep the diesel generator set in the best working condition. In order to achieve the purpose of fuel saving and fuel saving of the generator set, thereby reducing the use cost and reducing environmental pollution.
The above is the maintenance system provided by Quark Motor. Quark Motor has been specialized in the production of diesel generator sets for nearly ten years and is your most faithful backup power supply manager.
