  2. Overview • Project Background • Mission Statement • Customer Identification • PDS • House of Quality • Conclusion

  3. Project Background • 2.25% of energy required to operate a truck is lost in the drive train (fully loaded, level road, 1 hour) • Energy loss can be reduced by heating the axle lubricant • DTNA expects a 1% improvement in overall efficiency (approximately $800/year for each truck)

  4. Mission Statement • Design and build a device to achieve and maintain specified axle lubricant temperature range. (65-80 °C, 2 °C/minute) • Deliverables: • Working Prototype • Detail Drawings • Bill Of Materials • Detailed Design Report

  5. Customer Identification • Primary External Customer: • Daimler Trucks North America (DTNA) • Primary Internal Customer: • PSU (ME 492/493)

  6. Product Design Specification High Priorities • Device is to maintain a temperature range of 65-80 °C • Device must show an ROI within 2yrs • Device must improve net efficiency of vehicle enough to satisfy ROI • Device is to heat at a rate of 2 °C/min

  7. PDS Continued… • Device must weigh less than 20 lbs. • Device should be easily retrofitted • Device must comply with safety regulations • Device must be relatively low maintenance

  8. House of Quality

  9. Conclusion • The deliverables of this project will serve as a starting point for further development by Daimler. • There is a potential for a significant increase in efficiency. • Application will ultimately benefit the environment and reduce oil dependency.
