What is water-jacket?

A water-jacket is a cooling system used in engines to maintain a stable temperature. It is typically made of cast iron and encases the combustion chamber and other engine components like the cylinder block and head. The water jacket circulates coolant, usually a mixture of water and antifreeze, through channels or passages to absorb heat from these components. The coolant then flows to the radiator, where it is cooled before returning to the engine.

Water jackets have been used in various types of engines, including gasoline and diesel engines, as well as some industrial equipment and machinery. They are important for preventing overheating, which can cause significant damage to the engine and reduce efficiency. The coolant also helps prevent corrosion and rust within the engine.

The effectiveness of a water jacket is dependent on a number of factors, including the size of the cooling channels and the quality of the coolant used. Regular maintenance, including flushing and replacing the coolant, is also important for ensuring the proper function of the water jacket.
