Six Tips for Diesel Generator Set Engine Longevity

Mar. 08, 2023

We all know that the engine is an important part of diesel generator set, and its service life is likely to determine the service life of generator set equipment. What measures can we take in daily operation to extend the service life of the engine? Please see the six tips listed by Starlight.

Grinding means running-in. This is the basis for extending the service life of the engine. Both the new engine and the overhauled engine must be run-in according to the regulations before they can be put into normal operation.


Enough oil, water and air. If the oil supply is insufficient or interrupted, the diesel engine lubrication will be poor, the engine body will be seriously worn and even the shingles will be burnt; If the cooling water is insufficient, the engine temperature will be too high, the power will be reduced, the wear will be intensified, and the service life will be shortened; If the air supply is not timely or interrupted, it will be difficult to start, poor combustion, power reduction, and engine failure to run normally.


Clean means clean oil, water, gas and body. If the diesel and gasoline are not pure, it will wear the precision fitting body, increase the fitting clearance, cause oil leakage, oil dripping, reduce the oil supply pressure, increase the clearance, and even cause serious faults such as oil circuit blockage, axle holding, burning and so on; If the air contains a lot of dust, it will accelerate the wear of cylinder liner, piston and piston ring; If the cooling water is not pure, the cooling system will be blocked due to scale, which will prevent the engine from radiating heat, and the lubrication condition will become worse, and the engine body will be seriously worn; If the body surface is not clean, the surface will be corroded and the service life will be shortened.


That is, the valve clearance, valve timing, fuel supply advance angle, injection pressure and ignition timing of the diesel or gasoline engine should be checked and adjusted in time to ensure that the engine is in good condition, so as to save fuel and prolong its service life.


Check the fastening parts frequently. Due to the impact of vibration and uneven load during the use of diesel and gasoline engines, bolts and nuts are easy to loosen. The adjusting bolts of all parts shall be checked to avoid the accident of damaging the body due to looseness.


Use the engine correctly. Before driving, lubricating parts such as shafts and bearings shall be lubricated. After startup, the water temperature shall be above 40 ℃ before operation. Overload or low-speed operation for a long time is strictly prohibited. Before shutdown, unload the load and reduce the speed. After parking in winter, when the water temperature drops to 50 ℃, drain the cooling water (except for the engine with antifreeze). The engine shall be well maintained at ordinary times to keep the machine in good condition. Frequent observation and inspection shall be carried out, and faults found shall be eliminated in time.


The six tips listed above can help you maintain the engine effectively, which is equivalent to protecting the "heart" of the diesel generator set. It not only ensures the operation efficiency, but also extends the service life. Starlight Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China.
