Summary:

Diesel engine emissions regulations throughout the world have changed dramatically over the last 20 years, with the most stringent phase for medium/heavy duty being implemented starting 2007 - 2010. The general perception is, that combination systems including PM reduction devices and NOx aftertreatment, likely SCR will be applied, hence significant additional emissions equipment will need to be added to a diesel engine. The consequences of this will be increased space for packaging and increased cost, to meet the demanding regulations. Traditional substrate technology, while developing extensively for gasoline engines by use of higher cell densities has limitations when applied to CI diesel engines. New developments in substrate and coating technology now enable considerable improvement in the efficiency and packaging space needed to meet certain limit values. A novel approach combining a continuously operating PM-reduction with advanced "turbulent" SCR-catalyst in a special system configuration has been investigated in an engine cell program with a HDDE, demonstrating the capability to approach US 2010 emission limits with an extremely compact and cost effective design
