Emission Control Devices for Diesel Fleets

MECA – Who We Are MECA represents the world’s leading manufacturers of emission control technology for mobile sources Catalyst manufacturers Substrate manufacturers Exhaust component manufacturers Exhaust system integrators MECA members have extensive technical, manufacturing, and installation experience with the application of emission control technologies to a wide variety of on-road and off-road vehicles and equipment MECA members have verified many of the on-road and off-road retrofit technologies listed by EPA, ARB, VERT (Switzerland) 2 2

Diesel Retrofit Technology Highlights Many proven and commercial diesel retrofit technologies are available spanning a variety of applications On-road vehicles (long-haul trucks, drayage trucks, school buses, transit buses, garbage trucks, emergency vehicles) Off-road engines and equipment (construction equipment, port equipment, mining equipment, marine engines, locomotives, transport refrigeration units) Stationary diesel engines Larger variety of passive and active DPFs now available Hybrid DPFs DPFs for EGR engines Retrofit technologies can help reduce global warming Filter technologies provide reductions in black carbon Retrofit technologies provide multi-pollutant co-benefits Catalyzed devices reduce hazardous air pollutants (HAPs) ULSD availability enables the lowest emissions and ensures reliability

Diesel Retrofit Technology Highlights Funding for retrofits increasingly available at federal and state levels (DERA, CMAQ, SEPs, state incentives) American Recovery and Reinvestment Act of 2009 Cities/projects using “clean construction” requirements expanding Regulations/programs stimulate technology advances and help define market opportunity EPA’s Voluntary Diesel Retrofit Program ARB’s Diesel Risk Reduction Program State retrofit programs Tighter emission standards on new engines worldwide Verification process needs adequate technical resources Demonstration programs/funding help fill the retrofit verification pipeline EPA Emerging Technologies Program ARB/SCAQMD Off-Road Showcase Program Texas NTRD funding for NOx retrofits
