ENGINE CHARGE AIR COOLER NOMENCLATURE

1976-06-01
HISTORICAL
J1148_197606
This recommended practice is intended to outline basic nomenclature and terminology in common use for engine charge air coolers. An ENGINE CHARGE AIR COOLER 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 and/or mechanically driven blower. The use of an engine charge air cooler allows increased engine output because of the denser and cooler air available for combustion. Normal cooling sources are the engine’s coolant, a raw water source or air. Engine charge air coolers are often referred to as either INTERCOOLERS or AFTERCOOLERS depending upon their location, relative to the final compression stage, in the air induction system. Nomenclature sketches are presented below for the following general types of engine charge air coolers:

Engine Charge Air Cooler (CAC) Nomenclature

HISTORICAL
J1148_199006
This SAE Recommended Practice is intended to outline basic nomenclature and terminology in common use for engine charge air coolers, related charge air cooling system components, and charge air operating and performance parameters. An engine charge air cooler 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, an engine driven turbocharger, or a mechanically or electrically driven blower. The use of a charge air cooler allows increased engine horsepower output, and may reduce emission levels and improve fuel economy through a more complete combustion due to the increased air density available. Typical cooling media includes the engine's coolant, ambient air, or an external water or coolant source.

COOLANT CONCENTRATE (LOW SILICATE, ETHYLENE GLYCOL TYPE REQUIRING AN INITIAL CHARGE OF SUPPLEMENTAL COOLANT ADDITIVE) FOR HEAVY-DUTY ENGINES

1990-04-01
HISTORICAL
J1941_199004
This SAE Recommended Practice applies to engine coolant concentrate, low silicate ethylene glycol base, for use in cooling systems of heavy-duty engines. An initial charge of supplemental coolant additive (SCA) is required when using this type of coolant concentrate. This document applies to engine coolant concentrates for heavy-duty engine requirements. SAE J1034 applies to coolant concentrates for automobile and light truck applications. For further information on engine coolants, see SAE J814.
