Automotive or Car Engine Liquid Cooling System/ Water Cooling System Types: There are three types of liquid/water cooling system in a car or an engine and they are given below: 1.       Water Jackets cooling system. 2.       Water Pump cooling system 3.       Thermostat Valve cooling system 1.       Water Jackets cooling system: Water Jackets are designed to keep the cylinders cool. The water jackets are cast into the cylinder blocks and heads.    2.       Water pumps cooling system: The water pump is a impeller type and are mounted at the front end of the cylinder block between the block and the radiator. The pump consist of a housing, with a water inlet and outlet and an impeller. The impeller is a flat plate mounted on the pump shaft with a series of flat or curved blades or vanes.  3.       Thermostat Valve Cooling System: Thermostat valve warm up engine quickly. It engine cool engine.

Purposes of Engine cooling system: The purpose of the cooling system is to keep the engine at its most efficient operating temperature at all engine speeds and all driving conditions. Temperatures higher than this will cause the lubricating oil film to break down and lose its lubricating properties.                                                   Figure: Engine Water Cooling System Types of engine cooling system: There are two types of engine cooling system 1.       Air cooling system 2.       Liquid cooling system                                                    Figure: Engine Air Cooling System Most of the engine used liquid cooling such as car, motorcycles, airplanes and so on. 

Crankcase Ventilation: PCV means positive crankcase ventilation. Air from carburator air is drawn through the crankcase. This air carries pollution from oil to the intake manifold and burned in the cylinder with fuel.                 Engine Cooling System: The cooling system is used to keep the engine in the most efficient condition. About 30 to 35 %   of heat produced during combustion is removed by cooling system. Temperature during combustion rises to about 3300 o C in the cylinder. Types of Engine Cooling System: There are two types of   Engine Cooling System- 1.       Air cooled 2.       Liquid cooled. Main Components of Engine Cooling System:  Radiator,  pump fan,  cooling lines,     water jacket,  thermostat.
