How To Properly Maintain A Generator Set In Winter?

2021, La Niña is here, which could mean a cold and stormier winter than normal across the North .These conditions are expected to last through the Northern Hemisphere winter and maintain low temperatures for a long time, such a severe climate environment for the maintenance of the genset is undoubtedly a major test. What should we do ?

1. If we are often used diesel generator set outdoors, then in the winter we need to pay more attention to the change of local temperature, if the ambient temperature is lower than 4℃, we should put off the cooling water out off the cooling tank , so as to ensure that the cooling water will not be damaged because of the solidification of the water tank.

2. When we start up the diesel generator set in winter, we need to warm up the generator set in advance and start slowly. Because the air temperature inhaled in the cylinder is relatively low, it is difficult for the piston to compress the gas to reach the temperature of diesel spontaneous combustion. So after starting, should first run at a low speed for 3-5 minutes. After the overall efficiency of the diesel generator set is improved, check the condition of the lubricating oil again. If there is no problem, you can run normally.

3. In addition, in winter, we should change the air filter more frequently. Because the winter wind is relatively strong, more impurities in the air more impurities will get into air filter to damage the cylinder.Frequent air filter replacing will prolong the service life of diesel generator set. 

4. Well pre-heating preparation before starting , such as water jacket heater, space heater, reduce the machine from low temperature to high temperature sharp fluctuation change, reduce the consumption of generator parts.

5. Use reliable oil brand. In winter, the general choice of low viscosity oil. WAGNA oil and coolant , with German manufacturing process, are more reliable for genset maintenance.


In order to ensure the safe and reliable operation of the machine, it is necessary to pay attention to the maintenance of the generator set at ordinary times. If you want to know more knowledge about the maintenance of generator sets, please follow us on Linkedin, and Facebook .
