This SAE recommended practice is intended for use in testing and evaluating the performance of light-duty automotive electric engine cooling fan assemblies. These Electric Cooling Fan (ECF) assemblies are purchased by light-duty truck and passenger car OEMs from suppliers. They are purchased as complete assemblies, consisting mainly of the fan(s), motor(s), and shroud (see Figure 1); this Recommended Practice will only consider such complete assemblies. Some purchased assemblies using brush-type motors may also include digital control devices such as power resistors or pulse width modulation (PWM) electronics or local interconnect network (LIN) for speed control. In the case of brushless motor technology, the controller is an integral part of the motor where it also performs the commutation process electronically. The performance measurement would include fan output in terms of airflow and pressure, and fan input electric power in terms of voltage and current.

The document provides clarity related to multiple temperature coolant circuits used in on- and off-highway, gasoline, and light- to heavy-duty diesel engine cooling systems.Out of scope are the terms and definitions of thermal flow control valves used in either low- or high-temperature coolant circuits. This subject is covered in SAE J3142.

This recommended practice was developed primarily for marine and industrial type applications.

This SAE Recommended Practice is applicable to all liquid-to-gas, liquid-to-liquid, gas-to-gas, and gas-to-liquid heat exchangers used in vehicle and industrial cooling systems. This document outlines the test to determine durability characteristics of the heat exchanger from vibration-induced loading.

This document outlines the test to determine durability characteristics of the heat exchanger from vibration-induced loading.

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.

This SAE Recommended Practice presents general nomenclature and glossary of terms for oil coolers.

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.

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.

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.
