Abstract

The testing technique outlined in this SAE Recommended Practice was developed as part of an overall program for testing and evaluating fuel consumption of heavy-duty trucks and buses. The technique outlined in this recommended practice provides a general description of the type of equipment and facility which is necessary to determine the power consumption of these engine-driven components. It is recommended that the specific operating condition suggested throughout the test be carefully reviewed on the basis of actual data obtained on the specific vehicle operation and the fan. Because of the variation in size, shape, configuration, and mountings available in cooling fans, specific test devices have not been included. Purpose-This SAE Recommended Practice provides a recommended test procedure for measuring and comparing the power consumption of fans used on trucks or buses over a range of speeds. The resulting power consumption data is intended for predicting the fuel consumption of trucks and buses using these fans, and in comparing one fan versus another on the basis of power requirements.
