Test Method for Measuring Performance of Engine Cooling Fans

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J1339_201909
  • Current
Published 2019-09-30 by SAE International in United States
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. The performance at a given air density and speed also depends on the volumetric flow rate, or the pressure rise across the fan, since these two parameters are mutually dependent. These parameters depend on the pressure drop across the radiator core and the ram pressure due to vehicle…

Glossary of Engine Cooling System Terms

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J1004_201904
  • Current
Published 2019-04-22 by SAE International in United States
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.

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

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J2867_201902
  • Current
Published 2019-02-13 by SAE International in United States
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. This information could then be used to calculate the efficiency of the assembly, including aerodynamic efficiency of the fan and shroud, and electrical efficiency of the motor. The electric power consumption could…

Low-Temperature Coolant Circuit Nomenclature and Applications

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J3136_201811
  • Current
Published 2018-11-08 by SAE International in United States
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.

Thermal Flow Control Valve Nomenclature and Application

Cooling Systems Standards Committee
  • Ground Vehicle Standard
  • J3142_201811
  • Current
Published 2018-11-02 by SAE International in United States
The purpose of this SAE Information Report is to define common industry terminology and nomenclature relative to thermal flow control valves and to describe common thermal flow control valve applications in automotive, highway truck, mobile construction equipment, and industrial applications. This document is primarily directed at internal combustion engine or electric powered applications and the downstream systems to which power is provided, such as transmissions, hydraulics, air compression, etc. The information contained herein does not constitute an SAE Standard.
