Transcript of "Evolution of Heavy-Duty Vehicle GHG and Fuel Economy Standards"

  1. 1. Evolution of Heavy-Duty Vehicle GHG and Fuel Economy Standards The Importance of the 2011 US RuleDrew Kodjak, International Council on Clean Transportation
  2. 2. Global Regulatory LandscapeCountry/ Regulation 2010 2011 2012 2013 2014 2015 2016 2017 2018Region Type Regulation implemented starting MY Fuel Japan 2015 economy United GHG/Fuel Standard Regulation implemented starting MY 2014 Final rule States efficiency proposal ( mandatory DOT program starts MY 2016) GHG/Fuel Standard Canada Final rule Regulation implemented starting MY 2014 efficiency proposal Test Industry Regulation implemented starting MY Fuel Standard China procedure standard Final rule 2015 consumption proposal finalized proposal TestEuropean Mandatory efficiency reporting and GHG Technical studies procedure Union regulatory development finalized Additional reqs. for End-user Requirements for tractors and Additional reqs. for existing tractors and existing trailers andCalifornia purchase trailers (MY 2011+) trailers (<MY 2010) reefers (<MY 2010) requirements 2
  3. 3. US Technology Assessment  National Academy of Sciences Report (March 2010) found 35 – 50% improvement could be achieved in the 2015 to 2020 timeframe National Academy of Sciences (2010) FIGURE S-1 Comparison of 2015-2020 New Vehicle Potential Fuel Savings Technology for Seven Vehicle Types: Tractor Trailer (TT), Class 3-6 Box (Box), Class 3-6 Bucket (Bucket), Class 8 Refuse (Refuse), Transit Bus (Bus), Motor Coach (Coach), and Class 2b Pickups and Vans (2b). Also, for each vehicle class, the fuel consumption benefit of the Slide 3 combined technology packages is calculated as follows: % FCpackage = 1 – (1 - %FCtech 1)(1 - %FCtech2)(1 - %FCtech N) where %FCtech x is the percent benefit of an individual technology. SOURCE: TIAX (2009) ES-4.
  4. 4. Elements of US Rule: Three Vehicle Categories Class 7/8 Tractors Class 2B/3 Pickup Trucks and Vans Everything Else! Slide 4
  5. 5. US HDV GHG / Fuel Economy RuleUS program is four rules bundled together: Engine, Tractor,Vocational, Pickups and Vans.Vehicle Type Subclass Engine Vehicle only Vehicle + EngineTractors Day Cabs Class 7 Low/mid Roof 6% 4% 10.3% Class 7 High Roof 6% 7% 13.0% Class 8 Low/mid Roof 6% 3% 9.1% Class 8 High Roof 6% 8% 13.6% Sleeper Class 8 Low Roof 6% 12% 17.5% Class 8 Mid Roof 6% 12% 18.0% Class 8 High Roof 6% 17% 23.4%Vocational Light HD Class 2b - 5 9% 0% 8.6% Medium HD Class 6 - 7 9% 0% 8.9% Heavy HD Class 8 5% 1% 5.9%Pickups & Vans Gasoline 12.0% Diesel 17.0% Largest reductions – and regulatory attention – focus on the vehicle categories that use the most fuel. In HD sector, combination tractors and pickup trucks use about ¾ of the fuel. Slide 5
  6. 6. Baseline Engine + Vehicle (MY2010) Slide 6
  7. 7. Compliance Example: Working with the GEM Determined by testing “yes/no” parameters Slide 7
  8. 8. Class 8 Tractor Sleeper Cab High Roof Compliance Pathway 94 g CO2 / 94 g CO2 Ton-mile 23% Reduction 0.76 2.19 5.0 0.31 5.64 Overlap 72 g CO2/ton-mile (MY2017 Std) with Aero 6.86 Slide 8
  9. 9. Closing Thoughts  HDV GHG / fuel economy standards are a critically important area of regulatory development for the US and globally.  The search for continually improving upon regulatory design (metric, cycle, test method, etc) will continue for the next ve to ten years at least.  Important questions remain: –  Simulation modeling vs. chassis dyno –  Performance vs. technology standards –  Test method accuracy and repeatability –  Incorporating trailers –  Hybrid technology development and incorporation –  Opportunities for global alignment of programs Slide 9
