In winter, low temperature has a very bad impact on the diesel generator set, which will cause starting difficulty, power reduction, increased fuel consumption and even malfunction. Therefore, you should pay attention to the following points when using a diesel engine in winter:
1. Under low temperature conditions, diesel has high viscosity and poor fluidity, which will cause poor atomization and unstable operation of the diesel engine. , and even the interruption of oil supplies. In winter, it is therefore advisable to use diesel fuel that is fundamentally suited to the ambient temperature.
2. At lower temperatures, the viscosity of the engine oil increases, which increases the resistance to rotation of the crankshaft. When starting the diesel engine when the battery voltage remains unchanged, the diesel engine can be started byincreasing power. If conditions permit, winter engine oil can be used.
3. When the ambient temperature is around -35 degrees, after starting the diesel engine, if cold water is added to the water radiator, the cold water will enter the radiator and freeze immediately because the temperature is too low. Therefore, in areas where the ambient temperature is low, it is necessary to add antifreeze suitable for the ambient temperature into the radiator to prevent the body, radiator and water pump from freezing and cracking.
4. In areas with lower temperatures, the density of the battery electrolyte should be increased appropriately 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 be adjusted appropriatelyrequested to increase the charging current.
5. When starting the diesel engine in winter, it is best to add hot water to the radiator. It is never allowed to use a blowtorch or open flame to heat oil to reduce the viscosity or resistance of the oil. oil. The consequences of this will lead to deterioration of the engine oil and the formation of oil glue blocks in the combustion zone. In addition, it will easily cause the oil pan gasket to age and deteriorate.
