Over in Europe, Mercedes-Benz has just introduced a version of the diesel powertrain for its buses that passes the EEV emissions standards without having to use either a particulate filter (DPF) or selective catalytic reduction (SCR).

Corning has been selected to provide particulate filters to Navistar for its diesel engines. The traps and ceramic substrates will allow Navistar's engines to meet tougher 2010 EPA emissions standards for heavy duty trucks. Corning worked with Navistar to ensure its components were compatible with the engine maker's EGR systems.
