Water Cooled Diesel Engine

A water cooled engine has a water pump fitted which circulates water through the engine and the attached and the attached radiator which reduces the water temperature by passing air over the radiator fins, and it is a closed circuitWater has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and cost. Higher-power engines generate more waste heat, but can move more weight, meaning they are generally water-cooled.A water-cooled engine uses a closed loop cooling system; this means that the use of a waterpump and cooling fan can be in constant use to keep the flow of coolant coursing throughout the engine with the fan keeping it cool even when the car is stationary.An engine cooling water system consists of a thermostat, cylinder sleeve, cooling water pump and a heat exchanger (radiator).Water is used to cool radiators of engines because it has a high specific heat capacity. to cool by means of water and especially circulating water (as in a water jacket) water-cooling the engine.
