  1. 1. Robert Rinaca Booz Allen Hamilton Lead Associate Baltimore, Maryland APTA 2010 Bus and Paratransit Conference Affordable Hybrid Bus Technology For The Legacy Fleet
  2. 2. Existing Maintenance Issues and Costs <ul><li>Transit buses experience frequent and costly hydraulic system failures and leaks </li></ul><ul><li>New Flyer buses have been experiencing recurrent radiator failures </li></ul><ul><ul><li>Montreal, the manufacturer of the New Flyer radiators, replaced each radiator twice on each of the 219 New Flyers. </li></ul></ul><ul><ul><li>Montreal went out of business early in 2009 </li></ul></ul><ul><ul><li>The radiators continue to fail </li></ul></ul><ul><li>Alternator and regulator failures cause significant downtime on New Flyer and Neoplan buses. </li></ul><ul><ul><li>Niehoff, manufacturer of the New Flyer alternators, has replaced each alternator and regulator twice under warranty on each of the 219 New Flyers. </li></ul></ul><ul><ul><li>The New Flyer buses are now out of warranty </li></ul></ul>
  3. 3. MTA spends an estimated $1 million annually on repairs and cleanups related to hydraulic system failures <ul><li>MTA currently spends an average of $1 million annually on repairs for failed radiators, alternators, and hydraulic systems, and related cleanups, on the 2004/2005 model year New Flyers and 2002 model year Neoplans. </li></ul>Annual Cost of Radiator, Alternator, and Hydraulic System Failures on Neoplan and New Flyer Buses Model Parts Labor Total New Flyer $450,000 $150,000 $600,000 Neoplan $300,000 $100,000 $400,000 Total $750,000 $250,000 $1,000,000
  4. 4. Engineering Research and Investigation <ul><li>Researched possible solutions for replacing the current radiators </li></ul><ul><ul><li>Direct replacement with radiator.CAC from another manufacturer </li></ul></ul><ul><ul><li>New technology replacement to eliminate hydraulic fan drive </li></ul></ul><ul><li>Selected EMP mini-Hybrid for test installation </li></ul><ul><li>Developed prototype plan in conjunction with New Flyer </li></ul><ul><ul><li>Test installation completed on both diesel and hybrid buses </li></ul></ul><ul><ul><li>Full Modac tests and cooling tests completed </li></ul></ul><ul><li>Installation of EMP mini-Hybrid approved </li></ul>
  5. 5. EMP miniHybrid Thermal Management System reduces the need for hydraulic pump and is ideal for retrofitting existing fleets <ul><li>Thermal product designed to eliminate engine overheating </li></ul><ul><li>Kit includes a radiator, eight electric cooling fans, a smaller hydraulic tank, and a smaller hydraulic pump for the steering system </li></ul><ul><li>Ideal for retrofitting/refurbishing existing transit fleets </li></ul><ul><li>Benefits include better fuel economy, lower maintenance costs, improved safety by elimination of hydraulic leaks or fires, and improved emissions </li></ul><ul><li>Fans are reversible for cleaning </li></ul>
  6. 6. Before and After Photos of Engine Compartment
  7. 7. Before and After Photos of Radiator/CAC Installation
  8. 8. Preliminary MTA evaluation of EMP miniHybrid system demonstrates fuel economy improvement of 7-10% <ul><li>Reduces parasitic loads on engine, providing better fuel economy, reduction of greenhouse gases, and more power to the wheels. </li></ul><ul><li>MTA has been evaluating EMP miniHybrid setup on six buses since October 2008 </li></ul><ul><ul><li>Model year 2009 New Flyer Hybrids include EMP miniHybrid system factory installed </li></ul></ul><ul><li>MTA’s preliminary evaluation results demonstrate fuel economy improvement of 7-10% </li></ul><ul><ul><li>This would result in $774,487 in annual savings if installed on the New Flyer and Neoplan buses </li></ul></ul>Potential fuel savings from using EMP miniHybrid system Model Annual Mileage Fuel Economy 10% Fuel Savings Gallons $ New Flyer 10 million 3.27 mpg 305,810 $611,621 Neoplan 2.5 million 3.07 mpg 81,433 $162,866 Total 12.5 million N/A 387,244 $744,487
  9. 10. The cost of the miniHybrid campaign investment would be realized in 2 years and result in savings of $1.8 million annually afterward <ul><li>EMP miniHybrid campaign investment would be amortized in 2.3 years for New Flyer buses and 2.1 years for Neoplan buses. </li></ul><ul><li>MTA will continue to save approximately $1.8 million annually until the buses retire in 2015 (Neoplan) and 2017 (New Flyer) </li></ul>Annual Savings <ul><li>MTA spends an average of $1 million annually on parts and labor to repair hydraulic, radiator, and alternator related failures </li></ul><ul><ul><li>$2,740 for each New Flyer </li></ul></ul><ul><ul><li>$4,040 for each Neoplan </li></ul></ul><ul><ul><li>Total Savings: $1 million </li></ul></ul><ul><li>Preliminary analysis indicates 10% fuel economy savings </li></ul><ul><ul><li>$2,800 for each New Flyer </li></ul></ul><ul><ul><li>$1,650 for each Neoplan </li></ul></ul><ul><ul><li>Total Savings: $800,000 </li></ul></ul><ul><ul><li>Annual Savings </li></ul></ul><ul><ul><li>$1.8 million </li></ul></ul>Campaign Investment <ul><li>The cost of each EMP miniHybrid kit includes a radiator, charge air cooler, alternator, regulator, smaller hydraulic tank, power steering pump, and all necessary installation hardware. </li></ul><ul><ul><li>$12,750 per each New Flyer </li></ul></ul><ul><ul><li>$12,000 per each Neoplan </li></ul></ul><ul><ul><li>Total Cost: $4 million </li></ul></ul><ul><li>Retrofitting all of the 219 New Flyers and 99 Neoplans requires additional MTA labor costs </li></ul><ul><ul><li>$750 per each bus </li></ul></ul><ul><ul><li>Total Cost: $240,000 </li></ul></ul><ul><ul><li>Campaign Investment </li></ul></ul><ul><ul><li>$4.2 million </li></ul></ul>
