Description:
An aftercooler also known as an intercooler, is a device used to cool the compressed air that comes out of a turbocharger or a supercharger in an internal combustion engine. This cooled air is denser, allowing for more fuel to be burned and thus increasing engine power. It is a heat exchanger made up of a series of thin tubes or passages, with fins attached to the tubes to increase their surface area.

Attributes:
• Contains a series of fins that help to dissipate heat from the compressed air.
• Mounted to the engine using mounting points.
• withstand the vibration and thermal stresses of the engine compartment.

Applications:
An aftercooler is used to reduce emissions by lowering the temperature of the compressed air, which decreases the likelihood of pre-ignition or knocking. It is extensively used in Cat D10T Track Type Tractors.
