intercooler

An intercooler is a device used to cool a fluid, such as air, between successive heat-generating processes. In the context of engines, specifically supercharged ones, compressing air increases its temperature. To counteract this and allow more air into the cylinders, intercoolers (also known as aftercoolers) reduce the temperature of this compressed air. This process is crucial because hotter air is less dense, meaning less oxygen is available for combustion. By cooling the air, an intercooler increases its density, allowing more fuel to be burned and thus increasing the engine's power output. Intercoolers can be either air-to-coolant or air-to-air types.123
