How to Maintain Cummins Power Generation Engine
Engine fuel requirements of CCEC Cummins Power Generation
Fuel:
– Use high quality light diesel oil of temperature 0 or lower
– Using higher temperature fuel will clog the filter to reduce power
– Use higher temperature fuel to make engine starting difficult
– Drain the water from the fuel filter in the hot state after shutdown
– Replace filters regularly (250h)
– If the fuel used is dirty, the filter will be blocked in advance.
– Engine power will drop after the filter is clogged.
Engine oil requirements
lubricating oil:
– Viscosity meets SAE 15W40
– Quality meets API CD or higher rating
– Change oil and filter regularly (250h)
– Must use CF4 or above oil on the plateau
– The combustion condition of the engine in the plateau deteriorates, the oil pollution is very fast, and the oil life below the CF4 level is less than 250h.
– Exceeding the life of the engine will result in the engine not being properly lubricated, the wear will be intensified, and early failure will occur.
Lubricants used in the plateau:
– Quality meets API CF4 or higher
– If you use CD low grade oil, the oil change period should be shortened by half. NTA855M350 oil comparison test (15W40/CD&CF4).
Engine coolant requirements
Coolant:
– Use water filters or add DCA dry powder as required to prevent corrosion, cavitation and scaling of the cooling system.
– Check the seal of the tank pressure cap and the leakage of the cooling system to ensure that the boiling point of the coolant does not decrease and the cooling system is normal.
– Use coolant containing ethylene glycol + water or a manufacturer-approved antifreeze for environmental conditions in cold areas.
– Regularly check the DCA concentration and freezing point in the coolant.
Engine daily inspection and maintenance
Lubricating oil surface and cooling fluid surface
Fuel, oil, coolant leakage
Belt slack and wear
The fan is damaged or not
The sound has no abnormal sound
Smoke color is abnormal
Dynamic change
Oil pressure and cooling water temperatur
Weekly inspection and maintenance
Check the intake resistance indicator or replace the air filter.
Drain the water and sediment in the fuel tank/fuel filter.
If the fuel used is dirty or the ambient temperature is low, more condensate is produced in the fuel tank and filter.
The deposited water should be discharged every day.
Engine inspection and maintenance every 250h
Change engine oil
Change the oil filter
Replace fuel filter
Change water filter
Check the coolant DCA concentration
Check the coolant freezing point (cool season)
Check or clean the water tank heat sink blocked by dust
Every 1500h
Check and adjust the valve clearance
Check and adjust the injector lift
Every 4500h
Adjusting the injector and the fuel pump
Check or replace the following parts:
– supercharger
– water pump
– tensioner
– fan hub
– air compressor
- Charger
– cold start auxiliary heater
