With the development of society, human dependence on electricity is increasing. As a common backup power equipment, diesel engines have attracted more and more attention due to their convenience, speed, and ease of operation, and have become backup power products. For factories and enterprises, the efficiency of diesel engines has a direct impact on the output benefits of the enterprise. So, for how to use diesel engines well, especially in the cold winter season, how to do daily maintenance and some precautions for starting and running, today we will take you to understand the precautions for using diesel engines in winter:

Firstly, if a diesel engine is working outdoors, special attention should be paid to temperature changes in winter. When the temperature is below 0 ℃, the cooling water in the diesel engine's radiator should be drained, because when the temperature is below 0 ℃, the water will freeze into ice. At this time, the volume change is relatively large. When the water changes from liquid to solid, the expansion of the volume will damage the radiator of the cooling water tank, and in severe cases, the cylinder body will freeze and crack.

Secondly, in winter, due to the poor working environment of diesel engines, it is necessary to frequently replace the air filter elements. This is because the cold weather has particularly high requirements for the air filter elements and diesel engine filter elements. Assuming that timely replacement will increase engine wear and affect the lifespan of diesel engines.

Thirdly, when selecting engine oil for winter diesel engines, it is advisable to choose oil with a slightly thinner viscosity as much as possible.

Fourthly, when starting a diesel engine in winter, the air temperature inside the cylinder is very low, making it difficult for the piston to reach the natural temperature of diesel after tightening the gas. Therefore, before starting the diesel engine, corresponding auxiliary methods should be selected to measure the temperature of the diesel engine body.

Fifthly, after starting the diesel engine, it should be unloaded for 3-5 minutes, increase the temperature of the generator, and then check the working status of the lubricating oil. Only after everything is normal can it be put into normal operation. During the operation of a diesel engine, it is important to remember not to suddenly shut down. You should first unload the load and wait for the machine to run for a period of time before shutting down, otherwise the service life of the diesel engine will be greatly reduced over time.
