This SAE Recommended Practice provides test methods and criteria for evaluating the internal cleanliness and air leakage for engine charge air coolers. This SAE Recommended Practice also provides nomenclature and terminology in common use for engine charge air coolers, related charge air cooling system components, and charge air cooling system operational performance parameters.

Description

An engine charge air cooler (CAC) is a heat exchanger used to cool the charge air of an internal combustion engine after it has been compressed by an exhaust gas driven turbocharger or a mechanically or electrically driven blower (supercharger). The reduction in compressed air temperatures increases intake air density, providing more air mass flow and allowing more fuel delivery, with corresponding improvement in engine power output. The cooler charge also enables an optimized combustion process which improves both emissions and fuel economy performance. Typical cooling media include the engine's coolant, a low temperature coolant circuit, or ambient air.
