Exhaust Gas Recirculation (EGR) Cooler Nomenclature and Application

2022-11-22
CURRENT
J2914_202211
This document provides an overview on how and why EGR coolers are utilized, defines commonly used nomenclature, discusses design issues and trade-offs, and identifies common failure modes. The reintroduction of selectively cooled exhaust gas into the combustion chamber is just one component of the emission control strategy for internal combustion (IC) engines, both diesel and gasoline, and is useful in reducing exhaust port emission of nitrogen oxides (NOx). Other means of reducing NOx exhaust port emissions are briefly mentioned, but beyond the scope of this document.

ENGINE COOLANT CONCENTRATE—ETHYLENE-GLYCOL TYPE

1973-06-01
HISTORICAL
J1034_197306
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.

ENGINE COOLANT CONCENTRATE - ETHYLENE-GLYCOL TYPE

HISTORICAL
J1034_198807
This standard covers glycol-type compounds which, when added to engine cooling systems at concentrations of 50 - 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. Heavy-duty non-automotive and heavy-duty diesel engine coolant maintenance may require different measurement and test parameters due to differences in engine design and materials, and high mileage service requirements.

METHOD FOR DETERMINING POWER CONSUMPTION OF ENGINE COOLING FAN-DRIVE SYSTEMS

1994-09-01
HISTORICAL
J1342_199409
The technique outlined in this SAE Recommended Practice was developed as part of an overall program for determining and evaluating fuel consumption of heavy-duty trucks and buses. It is recommended that the specific operating conditions be carefully reviewed on the basis of actual installation data. Cooling requirements are affected by all heat exchangers that are cooled by the fan-drive system. These may include radiators, condensers, charge air coolers, or oil coolers. 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. Using known power/speed relationships for a given fan, this procedure can be used to calculate the fan-drive system’s power consumption for engine cooling systems using fixed-ratio, speed modulating, and on-off fan drives. This power consumption may then be used in determining engine net power per SAE J1349.

HEAVY DUTY NON-METALLIC ENGINE COOLING FANS—MATERIAL, MANUFACTURING AND TEST CONSIDERATIONS

1985-01-01
HISTORICAL
J1474_198501
All materials classified as nylons share certain basic characteristics. However, even within the seemingly limited realm of glass fiber reinforced nylons, many levels and combinations of physical, thermal, and environmental resistance properties are available. These properties result from such factors as the following: 1 Type of nylon (6, 6/6, 6/10, 6/12, etc.) 2 Percentage (by weight) of glass fibers 3 Diameter and length of glass fibers 4 Wetting agent used to promote adhesion between resin and fibers (if present) 5 Heat stabilizer (if present) 6 Impact modifier (if present) 7 Pigmentation (if present) In order to select a material with appropriate characteristics, the prospective manufacturer and end user should investigate the proposed application thoroughly, and maintain open communication with the various material suppliers.

This SAE Recommended Practice is applicable to oil-to-air and oil-to-coolant oil coolers installed on mobile or stationary equipment and provides a glossary of oil cooler nomenclature. Such oil coolers may be used for the purpose of cooling automatic transmission fluid, hydraulic system oil, retarder system fluid, engine oil, etc. This document outlines the methods of procuring the test data to determine the operating characteristics of the oil cooling system and the interpretation of the results.
