EPA ‘10 & EU VIExperience & Approach Dr. Uwe Zink Director, Emerging Industry Technologies Corning Incorporated April 4, 2011
Agenda • Regulatory framework • Engine technology & calibration approaches • System designs • Certification examples • Enabling framework • Experience to-date • Outlook –future regulations
Regulatory LandscapeEPA’10 required an 83% NOx reduction compared to 2007 OBD phases in Daimler Truck, MTZ Heavy Duty Conference 2009
Observed Engine Technology Approaches • High pressure flexible injection systems • Unit injector • Common rail • Cooled EGR • Fixed/WG or VG Turbo • Single stage • Dual stage • Turbocompounding
EPA’10 – EUVI General Calibration & Emission Control Approaches • EPA’10 Approach: • EPA’07 baseline with DPF • Add DeNOx (SCR) system • EUVI Approach • EUV baseline with SCR • Increased EGR • Add DPF system • US-FTP, NTE, PN • Implicit and very stringent compliance requirements (*): Observe wall flow filter in all EPA’10 systems
Example of actual design as on vehicle Example of an EPA’10 Emission control system: -MD & HD application - DOC + DPF + SCR Cummins, SAE GOT 9/2010

System Design and components selection for reduced system back pressure Daimler Truck, MTZ Heavy Duty Conference 2009
Fuel consumption and AdBlue Trade-off-Optimum provides benefit compared to EPA’07 systems Daimler Truck, MTZ Heavy Duty Conference 2009
-Optimum provides benefit compared to EPA’07 systems-Example shown at ~ 2.5 g/HPh NOx Cummins, SAE GOT 9/2010
Thermal Management approach to ensure SCR efficiency over cert & operating cycle Cummins, MinNOx 6/2010, SAE GOT 9/2010

DEF Infrastructure -evolving across North America -currently ~ 3,000 stations Diesel Exhaust Fluid will soon be sold at over 2,500 locations all over North America. http://www.detroitdiesel.com/emissions/epa2010/availability.aspx
AdBlue/DEF Logistics grown substantially in Europe Stations in Europe (3/29/11):3587 w/Pumps, 7333 w/Canisters http://www.findadblue.com/
Inj>220C Inj>180C The new mixer with revised calibration shows higher efficiency than without at all points. Point E is 181C; F is 225C. New mixer allows urea injection at T>180C-Key for thermal management and/or space mitigation Mixer has low pressure drop and high surface area. 4.8% max pressure drop in ESC (0.25 kPa) SwRI, SAE 2010-01-1185
Update on ammonia adsorption SCRFirst commercial contract -production trial in 2011. Amminex, CTI SCR Conf, 7-10
DPF Maintenance Aspects-addressed already for the EPA’07 systems • Assume low sulfur diesel (<50 ppm) is available • Filter cleaning/service –several concepts • On-vehicle -air assisted • Off-vehicle -air/liquid • In workshop • Centrally • Lube oil: Low SAPS (<1%) oil CJ-4 recommended by OEs • Still CI-4 (<1.4% SAPS) in use • Filter cleaning intervals depend on duty cycle • Experience: • Several applications exceed min. design of 150,000 miles SAPS: Sulphated Ash Phosphorus Sulphur
Observe long DPF regeneration intervals with high NOx/Low PM -some advertise “no active regeneration” http://www.tectrucks.com/assets/carbslideshow_volvo_scr.pdf

Summary • EPA’10 represents tightest emission regulation for commercial vehicle engines today • Typically met by advanced engine technology and DPF plus SCR systems • While meeting the regulations, OEs offered value to end user via reduced fuel consumption compared to 2007 engines • Typically higher NOx calibration with SCR DeNOx • Other engine based approaches observed as well • Urea infrastructure in US is rapidly building • Expect similar system designs for EUVI • Expect wall flow filter to meet PN regs across the board • Outlook • OBD next in US 2013 • CO2 regulations coming in 2014 (US), assume EU will follow with CO2 • Expect next round of engine/aftertreatment system evolution
