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:
The Cooling Systems Standards Committee is part of the Vehicle Engineering Systems Group and reports to the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to engine cooling systems and components for automobiles and light trucks, heavy duty on-and off-highway vehicles and industrial equipment. All standards reflect the latest technology and industry practice through advisement, consultation and cooperation with industry, government, educational institutions, the public, other standardizing bodies, and other SAE committees and members. Participants in the SAE Cooling Systems Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties, who assist the SAE Engineering Activity Board through the preparation and presentation of technical papers at national meetings and specialty conferences.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
