4 Comparison of Passenger car Emissions Standards NOx g/km Year Gasoline Diesel fuel Euro 3 Euro 4 New- short New-long Tier 1 NLEV Tier 2 Tier 1 Euro 3 Euro 4 New-long New- short Tier 2 NLEV Useful Life (km) Tier 2 : 193,080km Euro4 : 100,000km New-Long : 80,000km ( Nitrogen Oxide (NOx) limits )
5 Comparison of Heavy-Duty Diesel NOx & PM Standards g/kw-hr Year ( NOx, PM limits g/k-Wh) g/kw-hr New-Long Euro 3 Euro 4 New-Short NOxPM
6 Year Market Share (%) in California Implementation Rates for Conventional Vehicles In California The percentage requirements for ZEVs are mandatory starting in 2003
7 Goal is “Zero” Emissions US California HC NOx (g/mile) LEV I LEV II CBG Phase 3
8 Maximum sulphur content limits (ppm) Year Final target : sulphur free Sulphur Free Fuels for Diesel Fuel
9 World-Wide Fuels Harmonisation Category 1 Markets with no or minimal requirements for emission control; based primarily on fundamental vehicle/engine performance concerns. Category 2 Markets with stringent requirements for emission control or other market demands. For example, markets US Tier 0 or Tier 1, EURO 1 and 2 or equivalent emission standards. Regions of Asia, Europe and North America are now planning and implementing requirements for more stringent vehicle emissions control and reduced fuel consumption
10 World-Wide Fuels Harmonisation Category 3 Markets with advanced requirements for emission control or other market demands. For example, markets requiring US California LEV,ULEV and EURO 3 and 4, or equivalent emission standards. Category 4 Markets with further advanced requirements for emission control, to enable sophisticated NOx and PM after-treatment technologies. For example, markets requiring US California LEV-II, US Tier 2, EURO 4 in conjunction with increased fuel efficiency constraints or equivalent emission standards.
