Truck crane engine working cycle

When the crane is working, the gas temperature in the cylinder can be as high as 1937 ~ 2327 degrees. With the gap, resulting in movement of sports death. In addition, the high temperature will cause the mechanical parts of the engine strength decreased, so that the loss of oil and so on. The function of the engine cooling system is to cool the engine parts operating under high temperature conditions to ensure that the engine is operating at the optimum temperature.
The cooling strength of the cooling system must be appropriate, the cooling will make the engine overheat, too much cooling will make the engine temperature is too low, the engine overheating or temperature is too low will affect its normal work. At present, the car hanging on a wide range of water-cooled engine normal operating temperature (cooling water temperature) is generally 80 to 90 degrees. Depending on the cooling medium used, the engine cooling system can be divided into two types: water-cooled and air-cooled. Water cooling system with water or antifreeze (collectively referred to as coolant) for the cooling medium.
