The testing technique outlined in this SAE Recommended Practice was developed as part of an overall program for testing and evaluating fuel consumption of heavy-duty trucks and buses. The technique outlined in this recommended practice provides a general description of the type of equipment and facility which is necessary to determine the power consumption of these engine-driven components. It is recommended that the specific operating conditions suggested be carefully reviewed on the basis of actual data obtained on the specific vehicle operation. Because of the variation in size, shape, configuration, and mountings available in cooling fans and fan drive systems, specific test devices have not been included.

The technique outlined in this recommended practice provides a general description of the type of equipment and facility which is necessary to determine the power consumption of these engine-driven components. It is recommended that the specific operating condition suggested throughout the test be carefully reviewed on the basis of actual data obtained on the specific vehicle operation and the fan. Because of the variation in size, shape, configuration, and mountings available in cooling fans, specific test devices have not been included.

This report presents general nomenclature and glossary of terms for oil coolers.

This report is intended as a source of information concerning the basic properties of engine coolants which are satisfactory for use in internal combustion engines to provide corrosion protection, lower the freezing point, and raise the boiling point For additional information on engine coolants see SAE J1034a, Engine Coolant Concentrate—Ethylene Glycol Type.

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:

This standard covers glycol-type compounds which, when added to engine cooling systems at concentrations of 40-70% by volume of coolant concentrate in water, provide corrosion protection, lower the freezing point, and raise the boiling point of the coolant. Such compounds are intended for a minimum of 1 year (approximately 12,000 miles) service in a properly maintained cooling system. (Reference: SAE HS-40, Maintenance of Automotive Engine Cooling Systems.) Coolants meeting this standard do not require the use of supplementary materials. For additional information on engine coolants, see SAE J814.
