  1. EPA Tier 4 / EU Stage IV - Technical Overview Sept 2009

  2. Clean Diesel Exhaust requirements are dramatic Technology hurdles to meet the regulations Cost to the OEM, Cost to the Rental Channel, Cost to the end user. Regulatory Background Pre 1998 NOx (Nitrous Oxides) 1998 - 2000 2004 - 2005 2008 2011 - 2013 2014 - 2015 Particulate Matter (Soot)

  3. Technology Solutions

  4. Impact of EGR and SCR on End User SCR EGR Fuel DEF Larger cooling capacity required • Customers have to fill up with fuel and Diesel Exhaust Fluid (2 separate tanks) • Probably close to oil change interval. • Limp home mode. Oil-cooled obsolete Special fuel required. Will be an issue outside of US and EU.

  5. EGR cooler Crankcase Breather EGR valve EGR crossover tube EGR New Components Tier 3 Tier 4 Space consumed Maintenance required

  6. DPF and SCR Space Requirements DPF Only DPF + SCR + EGR Cooler DPF + EGR Cooler • These components must fit in the engine compartment • Engine size and Implementation Schedule affects technology solutions • Larger Engines will require DPF + SCR + EGR • Small engines may only require DPF Urea Tank

  7. Timing and Possible Solutions

  8. Tier 4 is a game changing event for off road equipment Engine solutions in the future will be much different than today Terex is working now to partner with the engine supplier that provides the best overall value proposition. Performance Quality/Reliability World wide support Emissions Technology Summary
