Engine Charge Air Cooler (CAC) Nomenclature
1990-06-01
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.

FAN HUB BOLT CIRCLES AND PILOT HOLES
1984-07-01
HISTORICAL
J635_198407
The scope of the specification is limited to heavy-duty diesel engine manufacturers, fan suppliers, and end users. Standard mounting patterns are given for fans up to 2000 mm rotating diameter. Passenger car and light-duty fans were not addressed because committee members issuing the specification felt that standards for these fans could be better addressed by personnel working in the market segments which use those fans. Rationale for issuance of the specification is cost savings through reduction of part numbers and inventory. Failure to comply with this specification will result in the need to release and carry in inventory parts of identical blade geometry and construction, but with different mounting patterns.

FAN HUB BOLT CIRCLES AND PILOT HOLES

HISTORICAL
J635_199506
The purpose of this SAE Recommended Practice is to encourage the standardization of mounting patterns for engine cooling fans as new engines are designed and developed in SI metric units. It is specifically not the objective of the specification to address the soft metric conversion of existing mounting patterns on engines designed in English units. The scope of the specification is limited to heavy-duty diesel engine manufacturers, fan suppliers, and end users. Standard mounting patterns are given for fans up to 2000 mm rotating diameter. Passenger car and light-duty fans were not addressed because committee members issuing the specification felt that standards for these fans could be better addressed by personnel working in the market segments which use those fans. See Figure 1 and Table 1. Rationale for issuance of the specification is cost savings through reduction of part numbers and inventory.

Glossary of Engine Cooling System Terms
2019-04-22
HISTORICAL
J1004_201904
The objective of this glossary is to establish uniform definitions of parts and terminology for engine cooling systems. Components included are all those through which engine coolant is circulated: water pump, engine oil cooler, transmission and other coolant-oil coolers, charge air coolers, core engine, thermostat, radiator, external coolant tanks, and lines connecting them.

CURRENT
J1468_202112
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.
