Requirements of Fuel, Oil and Coolant of Cummins Generator


Fuel requirements for Cummins generator set: Use high quality light diesel oil with lower temperature. Because of the higher temperature fuel used, the filter can be clogged to reduce power and cause engine starting difficulties.

After Cummins generator is shut down, remove the water from the fuel filter in a hot state and replace the filter regularly (250h). If the fuel used is dirty, the filter will be blocked in advance, and the engine power will decrease after the filter is blocked.



Requirements for lubricating oil of Cummins generator set:

1) Viscosity in accordance with SAE 15W40

2) Quality meets API CD or higher

3) Change the oil and filter regularly (250h)

Note: Engine oil of CF4 or above must be used on the plateau. Because the combustion condition of the engine in the plateau deteriorates, the oil pollution is very fast, the oil life below CF4 level is less than 250h, and the oil change period should be shortened by half. Oil that exceeds the life of the engine will result in the engine not being properly lubricated, the wear will be intensified, and early failures will occur.

Coolant requirements for Cummins generator set:

1) Use water filter or add DCA dry powder as required to prevent corrosion, cavitation and scaling of the cooling system.

2) Check the seal of the pressure cap of the water tank 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.

Note: The generator set operating in cold areas should use ethylene glycol + water coolant or antifreeze approved by manufacturer to meet the environmental conditions. It is also necessary to check the DCA concentration and freezing point in coolant regularly.

Diesel Generator Power Ratings: Standby vs Prime vs Continuous

Diesel generator sets are commonly used in a variety of sectors due to their dependable performance and high efficiency. They can be used for emergency power supply in the event of a power cut or used in places without connection to a power grid. When selecting a diesel generator for your home or business, you need to consider many factors, such as generator’s ratings. In this article, we’ll explain the three basic rating types - standby, prime, and continuous in diesel generators. ISO-8528-1:2018 defines basic generator set rating categories based on four operational categories: Emergency Standby Power (ESP), Prime Power (PRP), Continuous Power (COP) and Limited-Time Running Prime (LTP). Read on and learn the application of power ratings for engines used in generating sets. Standby Power Rating Standby Power(ESP) is used to supply emergency power when the external power supply is interrupted, such as power outages. Standby power rated generators can supply reliable electricity as t...

What Should You Pay Attention to in Routine Maintenance of Diesel Generator Sets

In modern society, the stability of power supply is directly related to the operation efficiency of enterprises and people's quality of life. Diesel generators have become an indispensable backup power supply or main power source in various industries due to their high efficiency, durability and reliability. However, to ensure the smooth operation and optimal performance of the generator sets, regular maintenance is essential. Here is what you need to pay attention to in the routine maintenance of diesel generators. Keep your generator clean It’s important to keep the generator’s exterior and the generator room clean. Regularly remove any dirt, dust, or debris that may accumulate to on the generator’s surface. This is not only for the sake of beauty, but also for the smooth operation of the unit. Cleaning the generator’s exterior, air intake vents, exhaust outlets and generator room can effectively reduce the risk of generator overheating. In addition, check if the connection bol...
