What is waterjacket?

A water jacket is a type of jacket or cover that surrounds an engine, typically a combustion engine, and is filled with water. The purpose of the water jacket is to absorb and dissipate the heat generated by the engine during operation. The heat from the engine is transferred to the water through a network of pipes or channels, and the water is then circulated to a radiator where it is cooled before being returned to the water jacket.

Water jackets are commonly used in vehicle engines, such as cars, trucks, and boats, as well as in industrial and agricultural equipment. They are essential for preventing overheating and engine damage caused by excessive heat. The design and size of water jackets vary depending on the application, engine size, and operating conditions.

Water jackets can be made from a variety of materials, including cast iron, aluminum, and copper. The use of water jackets has significantly improved engine performance and efficiency, while also contributing to reducing emissions and improving fuel economy.
