- After operating a diesel engine in winter, if it is parked outdoors, close attention should be paid to weather changes. When the ambient temperature drops below 4°C, the cooling water in the radiator should be drained in time. At around 4°C, water begins to expand as it freezes, and this increase in volume may damage the radiator.
- Due to the harsh operating environment in winter, the air filter should be checked and replaced more frequently. Cold weather places higher demands on both the air and diesel filters. Failure to replace them in time may lead to increased engine wear and reduced service life.
- When selecting engine oil for winter use, choose oil with a lower viscosity to ensure proper lubrication performance at low temperatures.
- When starting a diesel engine in winter, the intake air temperature is low, making it difficult for the compressed air in the cylinder to reach the ignition temperature of diesel fuel. Therefore, appropriate auxiliary measures should be taken to preheat the engine before starting.
- After starting, let the engine run at low speed for 3–5 minutes to gradually increase its temperature and check the lubrication condition. Only after confirming normal operation should the generator be put into full load operation. During operation, avoid sudden acceleration or running at full throttle immediately, as this may reduce the service life of engine components such as the valve system.
