Transcript

  • 1. Global Trends in Reducing Vehicular Emissions Anup Bandivadekar September 29th, 2011
  • 2. WHO estimated 1.34 million premature deaths from outdoor air pollution in 2008. Slide 2
  • 3. What pollutants are of concern? Greenhouse Gases Haze- CO2, Methane, Black Carbon, N2O, HFC Ozone (VOC + NOx) Particles (PM10/PM2.5) Toxics NOx, SOx, VOC, ammonia - Diesel particles - Benzene - Heavy metals Carbon monoxide (CO) 3   Michael Walsh"
  • 4. Comprehensive approach should treat vehicles and fuels as a system  Reducing fuel consumption –  Policy instruments include fuel economy standards, fee and rebate schemes etc.  Reducing criteria air pollutants –  Policy instruments include new vehicle emission standards (Euro V/VI and/or US Tier II/III), and in- use emission control strategies  Improving fuel quality –  Reducing carbon content of fuels –  Reducing sulfur content of fuels to near zero levels (<10 ppm) Slide 4

  • 7. New vehicle emission standards are getting tougher   Exhaust emissions standards –  Tighter standards •  Euro 6/VI: PM and NOx aftertreatment on all diesels (DPF +SCR) •  By 2020, EU motorcycle emissions down to Euro 5 level •  California LEV III/ US Tier III: SULEV average by 2022 –  Improved test cycle, cold start measurement, particle number limit, increased durability   Evaporative emissions –  Whole vehicle diurnal plus hot soak standards – near zero emission expected from all vehicles including E10 vehicles –  On-board Refueling Vapor Recovery (ORVR) Slide 7
  • 8. Much cleaner diesel vehicles are possible, through stricter standards and/or retrofits.DPFs are typically installed on new diesel passenger vehicles with Euro Vstandards and on heavy duty vehicles with Euro VI standards, but can beretrofitted to older diesels provided <50 ppm sulfur fuel is available. Slide 8   Cleaire Advanced Emission Controls LLC"
  • 9. Manufacturers responsible for in use emissionsover full range of real world driving conditions.  In-use compliance tests –  Detection of type speci c design related defects or inadequate maintenance instructions  Strengthening of on-board diagnostics –  Frequency of monitoring: In use performance ratio (IUPR) monitoring  Periodic exhaust inspection –  High opacity as measured on snap acceleration test may indicate engine malfunction and increased emissions of air pollutants, primarily unburned fuel hydrocarbons or soot particles. Slide 9
  • 10. Petrol and Diesel Certi cation Levels Emissions certification values for +600 model passenger cars in Germany, model years 2003 (Euro 3), 2007 (Euro 4) and 2010 (Euro 5). Source: Kraftfahrt-Bundesamt (KBA), Germany, 2011
  • 11. Emission reductions must be achieved in real world driving: e.g. Poor SCR performance at low exhaust temperaturesNot-To-Exceed Limit provides a way to limit off-cycle emissions Slide 11   Joint Research Center (JRC), 2011"
  • 12. Roadmap for the next decade is missing in India  Auto Fuel Policy of 2003 recommended revision every ve years –  Need to continue to treat vehicle and fuel as a system, fuel quality improvements critical for next phase of standards  Long term roadmap needed quickly to give industry adequate lead-time –  Technology already in the market, but on limited models in India  One Country, One Fuel, One Regulation! –  Availability of <50 ppm sulfur fuel countrywide opens up the possibility of leapfrogging to Euro VI standards –  10 ppm sulfur fuels needed countrywide eventually for optimal performance of after-treatment devices
