When the diesel generator is used in winter, it will be difficult to start due to the low ambient temperature, or even unable to start, or the body will freeze and crack due to the low freezing point of the cooling water. Therefore, in order to restore the normal working condition of the diesel generator in severe cold winter, the unit heating system should be turned on: coolant heating system, engine oil heating system and fuel heating system. Here, diesel generator manufacturers will analyze the necessity and sufficient reasons for turning on the heating system in winter.

1. Fuel system heating device

In order to prevent diesel generators from being blocked by diesel oil and unable to quickly enter the working state, the outdoor temperature is usually lower than 5 degrees Celsius. Yes (for No. 0 diesel), turn on the electric heating function of the diesel generator in winter.

Because diesel oil contains a certain amount of wax, when the temperature is low in winter, these waxes will gradually separate out, and even cause the diesel oil to condense and cannot flow. When the wax separated from the diesel starts to block the filter and affect the normal oil supply of the oil circuit, the temperature at this moment is called the cooling point of the diesel.

Taking No. 0 diesel oil as an example, its freezing point is 0 degrees Celsius and its cold filter point is 4 degrees Celsius. Usually when the outdoor temperature is lower than 5 degrees Celsius, the electric heating function is turned on, so that the state of the diesel oil is saturated, and it can be put into operation at any time. Electric heating consumes a certain amount of electricity, so care should be taken to turn on this function at the correct temperature. For example, this feature should no longer be turned on at temperatures well above the cold filter point of the diesel being used.

 In general, turning on the electric heating function at an appropriate temperature can make the diesel generator work at any time.

 2. Heating and cooling system

 As the temperature drops in winter, the diesel generator coolant also decreases or even solidifies. Therefore, diesel generator manufacturers generally recommend that users use antifreeze as the cooling medium at this time to prevent the cooling water from freezing and cracking the body due to the low freezing point. In such a situation, it is necessary to turn on the coolant heating system to ensure a certain temperature of the coolant. Such a temperature is also a guarantee for the rapid start of the diesel generator.

 3. Engine oil is heated in winter

 Due to the poor fluidity of the diesel generator oil used in summer in winter, it will bring a certain resistance when starting the diesel generator. At this time, the diesel generator manufacturer recommends that the user use the winter engine oil correctly, in addition to ensuring the flexibility of starting the diesel generator To a certain extent, the oil heating system needs to be turned on, which not only ensures the temperature when the engine starts, but also ensures sufficient fluidity of the oil and reduces the difficulty of starting in winter.
