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

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. For fan power/speed relationships, refer to SAE J1339.
