(1) Radiator (2) Air line connections from the turbochargers (3) Aftercooler core (4) Air line connections to the inlet manifoldHeated air that is compressed from the turbochargers is forced to the aftercooler. The air flows through aftercooler core (3) and the temperature of the compressed air is lowered. The combustion efficiency increases because of the cooler inlet air. This helps to provide lowered fuel consumption and increased horsepower output. Aftercooler core (3) is a separate cooler core that is mounted in front of the engine radiator. The engine fan and the ram effect of the forward motion of the vehicle causes ambient air to move across both the aftercooler cores. This cools the turbocharged inlet air.
