When the engine is running, the temperature in the cylinder reaches 1800 – 2000 DEG C, and the instantaneous temperature is as high as 3000 DEG C.
Baotou beiben heavy truck parts engine overheating caused by the engine preignition, reduce the amount of air, the increase of friction loss, can also lead to lower the viscosity of lubricating oil, oxidation, accelerated wear of parts, the engine power, economy, reliability and durability of the overall deterioration, serious, and can make the moving parts lose the normal clearance due to thermal expansion, causing the piston to move the “cylinder” or stuck so vicious failure. The data show that when the coolant temperature is from 90. C rose to 120. C, the power is reduced by about 5%.
If the engine is cold, a large amount of heat is the cooling water and the air away, increasing the heat loss and mechanical loss, the wear of the parts also increased, but also to the pre combustion period is too long, the engine crude, and idling bad, it is difficult to start. The data show that when the coolant temperature is from 90. C down to 40. C, fuel consumption increased by about 30%, power is reduced by about 10%; when the temperature from the 80. C down to 30. C, wear iron will increase about 5 times. Therefore, Baotou North heavy truck parts engine must maintain normal working temperature.
Baotou North heavy truck parts of the engine is too hot or too cold to reflect the temperature of the cooling medium, under normal circumstances, the optimal temperature of the engine is 80~90. C, higher than this value for overheating, below this value for supercooling. It has been proved that the performance of the engine is reduced, and the service life is shortened.
