Charge Air Cooler

Each engine is equipped with a charge air cooling system. The
function of the charge air cooler is to cool the hot compressed air
before it enters the engine's intake manifold. This system uses
ambient air as the cooling medium by allowing the intake air to
pass through a network of heat exchanging fins and tubes prior
to entering the combustion chamber. The resulting cooler intake
air is denser than uncooled air and will allow additional fuel to be
injected for greater power while helping to reduce emissions.
