Heavy Duty Diesel Engine Emissions Western Europe: Euro 6 Israel: EPA 2013 / Euro 6 Russia / CIS: Euro 5 South Korea: Euro5 US & Canada: EPA 2013 Japan: Local regs Mexico: EPA 2004 / Euro 4 2018: EPA 2010 / Euro 6 Turkey: Euro 6 China: CN 4 (Euro 4) This slide has been updated to reflect the changes that have taken place globally. The countries highlighted in yellow reflect recent significant changes. Mexico regulations remain unchanged from 2012 and currently allow EPA 2004 and Euro 4 compliant engines. In 2018, Mexico will require EPA 2010 or Euro 6 compliant engines. Colombia, one of the largest markets in South America requires Euro 4 emissions. Chile currently requires Euro 5 emissions. Brazil remains unchanged from last year and is currently Euro 5. There are no published dates for implementing Euro 6. China transitioned to Euro 4 in the middle of 2012. The implementation of Euro 5 remains undecided at this time. Russia requires Euro 5. While each country has different regulations, we have a portfolio of EPA and Euro engines to meet your global needs.

Diesel Emission Standards This graph displays the difference between the EPA and Euro emission standards. You will see particulate matter on the X-axis and NOX on the vertical axis. With each successive emission standard the emission levels have been reduced. 2

Architecture Maximum (PPM) Fuel Standards Euro Emission Level EPA Emission Level Sulfur Content (PPM) Architecture Maximum (PPM) Euro 2 EPA 98 Unlimited EPA 04 500 Euro 3 350 Euro 4 50 EPA 07 15 EPA 10 Euro 5* 10 Euro 6* TBD This slide displays the maximum sulphur content of the fuel that each engine emission level can burn without affecting the emission system. Exceeding the sulphur limits may result in failures of the emission systems depending on what is installed and can cause the engine to derate. Engines shown with unlimited sulphur levels do not have emission systems. * On Board Diagnostics 3
