Fuel Savings and Noise Reduction with the Fan Drive 801013

Cooling fan engagement times were recorded on a front-end loader used in heavy duty operation at varying ambient temperatures to determine the effectiveness of a temperature controlled fan drive on off-highway equipment. The benefits of the fan drive are presented In terms of fuel savings and noise reduction. The annual fuel savings were calculated for heavy duty operation at ambient temperatures typical to the Indianapolis area. Noise performance is indicated as the percentage of total operating time that the fan speed is above a speed required to cause the fan to be a major noise contributor and the measured noise reduction during fan disengagement.
