  3. Outline Project Introduction Hybrid Technologies Our Hydraulic System Prototyping Testing Results Business Plan Conclusions

  4. Project Introduction Context  Efficient energy usage Problem  Inefficient vehicle use can be unavoidable in some applications Solution Improve efficiency with the hydraulic hybrid system

  5. Overall Project Goal Validate Hydraulic Hybrid System can increase stop and go fuel efficiency by 40%

  6. Design Norms • Stewardship • Transparency • Caring

  7. Hybrid Technologies • Electric • Toyota Prius • Flywheel • Formula 1 • Hydraulic • UPS

  8. Benefits of a Hybrid System Regenerative braking Optimal engine performance Decreased brake maintenance

  9. Benefit of Hydraulic Hybrids • Less energy conversions • Electric • Hydraulic

  10. Two Types of Systems Series Parallel www.Eaton.com

  11. Hydraulic System

  12. Hydraulic System: Accelerating

  13. Hydraulic System: Coasting

  14. Hydraulic System: Braking

  15. Prototypes Base Case Hydraulic Hybrid

  16. Base Case Cart:Frame

  17. Base Case Cart: Gas Engine Mounting

  18. Base Case Cart: Drive Train

  19. Hydraulic Hybrid Cart • Removed base case drive train • Retrofitted cart with hydraulic components • Hydraulic Pump • Hydraulic Motor • Accumulators • Reservoir • Hydraulic Valves

  20. Hydraulic Hybrid Cart

  21. Reservoir

  22. Hydraulic Pump

  23. Accumulators

  24. Flow Control Valves

  25. Hydraulic Motor (www.grainger.com)

  26. Other Components • Redundant Brakes • Hydraulic • Mechanical • Linkages • Gas pedal • Brake pedal

  27. Hydraulic Hybrid Retrofit Costs

  28. Test Procedure

  29. Testing Video

  30. Results 52.4% increase in average stop and go fuel economy

  31. Improvements • Different pump or hydraulic motor • Variable displacement motor • Check valves with lower cracking pressure • Design to eliminate minor losses

  32. Business Plan • Target Market • Package delivery, garbage trucks, city buses • Introduction to the market • O.E.M. • Retrofit is to expensive • Potential Savings • Higher gas mileage, lower maintenance costs

  33. Business Plan • Feasibility • High cost on prototype • Pay back period is 19 years at current gas prices ($4.20) • Longer than the life of the vehicle

  34. Obstacles Budget Time Experience with Hydraulic Systems Component Failure

  35. Conclusions • Met our goal! • Met efficiency expectations • Proved our system works • Very expensive system • Learned a lot • Had fun!
