Test Method for Measuring Performance of Engine Cooling Fans

2019-09-30
CURRENT
J1339_201909
This SAE Recommended Practice is intended for use in testing and evaluating the approximate performance of engine-driven cooling fans. This performance would include flow, pressure, and power. This flow and pressure information is used to estimate the engine cooling performance. This power consumption is used to estimate net engine power per SAE J1349. The procedure also provides a general description of equipment necessary to measure the approximate fan performance. The test conditions in the procedure generally will not match those of the installation for which cooling and fuel consumption information is desired. The performance of a given fan depends on the geometric details of the installation, including the shroud and its clearance. These details should be duplicated in the test setup if accurate performance measurement is expected.

Quick Connect Fluid Coupling Specification for Water/Glycol Coolant System Interconnect

2019-07-22
WIP
J3207
This SAE Recommended Practice defines the dimensional characteristics and minimum performance requirements for quick connect couplings between flexible tubing or hose and rigid tubing or tubular fittings used in glycol/water coolant systems. This document applies to automotive and truck applications under the following conditions: a. Gasoline, diesel, hybrid, and electrical propulsion cooling systems. b. Operating pressure up to 206 kPa, 2.06 bar, (30 psig). c. Operating temperatures from -40 °C (-40 °F) to 125 °C (260 °F). Quick connect couplings function by joining the connector to a mating end form typically without the use of tools. The requirements stated in this document apply to new connectors in assembly operations unless otherwise indicated.

Laboratory Testing of Light-Duty Vehicle Electric Cooling Fan Assemblies for Airflow Performance

2019-02-13
CURRENT
J2867_201902
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.
