As winter approaches, the temperature drops, and the operating environment of diesel generators changes. If we fail to operate them in a standardized manner, it will cause varying degrees of damage to the generators. The following is a summary of precautions for using diesel generators in winter for your reference: I. Problems existing in the use of diesel generators in winter: 1. At low temperatures, oil viscosity increases, which increases crankshaft rotation resistance. When starting the diesel engine with the battery voltage unchanged, the starting can be done by increasing the electric quantity. If conditions permit, winter-grade oil can be used. 2. Under low-temperature conditions, diesel has high viscosity and poor fluidity, which will cause poor atomization, unstable operation of the diesel engine, and even interruption of fuel supply. Therefore, in winter, diesel oil that is basically suitable for the ambient temperature should be selected. 3. In areas with relatively low temperatures, the density of battery electrolyte should be appropriately increased according to temperature changes. At the same time, due to the large starting resistance, the battery discharge current increases. At this time, the regulator of the charging generator should also be appropriately adjusted to increase the charging current. 4. When starting the diesel engine in winter, it is better to add hot water to the radiator. It is strictly forbidden to use a blowtorch or open fire to heat the oil to reduce its viscosity or resistance. Doing so will cause the oil to deteriorate and form oil lumps in the burning area, and it will also easily age and deteriorate the oil pan gasket. 5. When the ambient temperature is around -35℃, if cold water is added to the water radiator immediately after the diesel engine is started, the cold water will freeze instantly when entering the radiator due to the extremely low temperature. Therefore, in areas with low ambient temperatures, antifreeze suitable for the ambient temperature should be added to the radiator to prevent the engine block, radiator and water pump from freezing and cracking. II. Some illegal operations to avoid during the use of diesel generators in winter: 1. Baking the oil pan with an open flame. Baking the oil pan with an open flame not only affects the service life of the engine, but also easily deteriorates the oil and reduces the lubrication effect. 2. Removing the air filter for ignition startup. Removing the air filter for ignition startup will allow unclean air to enter the cylinder, valves and other moving parts, accelerating the wear of these parts. 3. Starting without adding cooling water. If cooling water is not added during startup and is added only after the diesel engine is started, the water tank with increased temperature will encounter cold water suddenly, causing cracks in the engine block and cylinder head. 4. Heating the fuel tank with an open flame. Heating the fuel tank with an open flame will not only damage the paint on the surface of the engine block, but also easily burn the plastic oil pipes, causing oil leakage, and even cause an explosion due to the rapid expansion of gas in the fuel tank, resulting in danger. 5. Adding oil through the intake pipe. Adding oil through the intake pipe will cause carbon deposits on the piston and piston ring, reducing their service life. 6. Forcing startup with other power sources without preheating. Forcing the diesel engine to start with other power sources without preheating will cause dry friction or semi-dry friction between the crankshaft and bearing bushes, which may easily lead to crankshaft seizure.
