What is the “intercooler” and what does it do?
• When a gas is compressed into a smaller volume, both the pressure and the temperature of the gas increases. The same thing happens when the turbocharger compresses the intake air charge. To reduce NOx pollution and improve engine efficiency, the Ram uses an aftercooler to remove some of the heat from the intake air. • The aftercooler is behind the grill and appears to be a second radiator. • Note: Technically, the Ram Cummins uses an aftercooler. An intercooler is an intermediate charge air cooler between two stages of turbo charging and/or supercharging. An aftercooler is a cooler following a turbocharger or supercharger. • The Ram intercooler is constructed of aluminum.
