Diesel generator is affected by its own diesel combustion during operation, which will lead to sudden rise of diesel engine temperature. In high temperature environment, it will not only affect the improvement of working efficiency of diesel generator, but also cause the occurrence of parts failure. Based on this, we need to cool the heating part, which involves the problem of adding coolant to the diesel engine cooling system. What is the effect of the coolant on the operation of diesel generator set? 1.Antifreeze Under the condition of low temperature, the cooling system of diesel engine is not damaged. Generally speaking, the freezing resistance temperature of common coolant is that the freezing point is between 20 ℃ and 45 degrees below zero, and it is reasonable to choose according to the actual needs of different regions. 2.Anti boiling effect Under high temperature, it is ensured that there will be no premature boiling. The boiling point of common coolant is ...
