Northbound v3 accessories engine at work why to keep the cooling water temperature normal?

The normal operating temperature of the engine is expressed in terms of the normal temperature of the engine. Therefore, the normal and abnormal temperature of the cooling water mark the engine’s thermal state. Engine overcooling or overheating, will reduce the use of the engine performance, shorten the service life. The engine operating temperature is too low, will make the gasoline engine mixture can not be formed, the diesel engine rough, heat loss and mechanical loss increases, parts wear also increased; engine operating temperature overheating, will make North Ben v3 accessories engine produce early burn, And even the North Ben v3 accessories piston, piston rings and other sports parts of the thermal expansion of the loss of normal clearance, resulting in “card cylinder”, “pull cylinder” and other accidental damage. Due to the impact of high temperature, but also make the viscosity of lubricating oil decreased, the engine wear and tear, and ultimately affect the engine power, economy and reliability. Therefore, the engine must maintain a normal operating temperature during operation, even if the engine to maintain the best operating temperature of 80 ~ 90 ℃.
