Project BackgroundProject Background

►2.25% of energy required to operate a 2.25% of energy required to operate a truck is lost in the drive train (fully truck is lost in the drive train (fully loaded, level road, 1 hour)loaded, level road, 1 hour)

►Energy loss can be reduced by heating Energy loss can be reduced by heating the axle lubricant the axle lubricant

►DTNA expects a 1% improvement in DTNA expects a 1% improvement in overall efficiency (approximately overall efficiency (approximately $800/year for each truck)$800/year for each truck)

Mission StatementMission Statement►Design and build a device to achieve Design and build a device to achieve

and maintain specified axle lubricant and maintain specified axle lubricant temperature range. (65-80 °C, 2 temperature range. (65-80 °C, 2 °C/minute) °C/minute)
