Test Method for Measuring Performance of Engine Cooling Fans

J1339
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.

Test Method for Determining Power Consumption of Engine Cooling Fan Drive Systems

J1342_200706
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 know 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.

This SAE Recommended Practice is intended for use in testing and evaluating the approximate power consumption of engine cooling fans. This power consumption would then be used to estimate net engine power per SAE J1349. The procedure also provides a general description of equipment necessary to measure the approximate fan power consumption in a vehicle installation. The test conditions in the procedure generally will not match those of the installation for which fuel consumption information is desired. The power required by 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 power measurement is expected. Required power at a given air density and speed also depend on the volumetric flow rate, or else the pressure rise across the fan, since these two parameters are mutually dependent.

Cooling requirements are affected by all heat exchangers that are cooled by the fan drive system. These may include radiators, condensers, charge air coolers, oil coolers, and others. 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, viscous or speed modulating, and mechanical on/off fan drives including electronically activated fan drives.

J1393_199403
This document supersedes SAE J819 - Engine Cooling System Field Test. The purpose of this SAE Recommended Practice is to establish a testing procedure to determine the performance capability of engine cooling systems, including charge air coolers, on heavy-duty vehicles with liquid-cooled internal combustion engines. The definition of heavy vehicles for this document includes, but is not limited to, on- and off-highway trucks, cranes, drill rigs, construction, forestry and agricultural machines. Vehicles equipped with side or rear-mounted radiators may require an alternate procedure of a towing dynamometer because of peculiar aerodynamics. Testing is generally conducted to determine compliance with cooling criteria established by the engine manufacturer or the end product user to meet a desired engine reliability goal.
