In order to prevent the coolant from boiling, the cooling system is designed to be pressurized. Under pressure, the boiling point of the coolant is raised considerably. However, too much pressure will cause hoses and other parts to burst, so a system is needed to relieve pressure if it exceeds a certain point. The job of maintaining the pressure in the cooling system belongs to the radiator cap. The cap is designed to release pressure if it reaches the specified upper limit that the system was designed to handle. Water pumps have many designs, but most are the centrifugal type. They consist of a rotating fan, or impeller, and seldom are of the positive displacement type that uses gear or plungers. Many water pumps have a springloaded seal to avoid leakage of water around the pump shaft. Some Vtype engines have a pump on each cylinder block. Radiator is a device designed to dissipate the heat, which the coolant has absorbed from the engine。無錫職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計說明書 ( 論文 ) 1 英文翻譯： 原文： The Cooling System The engine cooling system actually is a temperature regulation system to protect engine from selfdestruction. About onethird of the heat produced in the engine is converted into power, another third goes out through the exhaust pipe unused, and the remaining third must be carried away by the cooling system (Some is utilized for heating the passenger partment). To keep the engine temperature in balance is quite essential for an engine to produce power. If the engine runs too hot, it may suffer from preignition since the airfuel charge is ignited p
