1. Liquid Cooling System: In a liquid cooling system, a liquid coolant (usually a mixture of water and antifreeze) circulates through the engine block and cylinder head, absorbing heat from the engine components. The heated coolant is then pumped to a radiator, where it is cooled down by airflow and returned to the engine.
2. Air Cooling System: In an air cooling system, the engine components are directly exposed to the airflow. Fins or cooling ribs are used to increase the surface area of the engine components, thus enhancing heat dissipation. The incoming air is directed over the engine components and flows out, carrying away the heat. Air cooling systems are typically used in small engines, such as those found in motorcycles and lawnmowers.
