Its SCR technology is one of several developed to meet demand spurred by more stringent regulations.Iselin-based Engelhard (NYSE: EC) today said it has successfully commercialized an emissions-control technology for heavy-duty diesel trucks that comply with stringent new regulations in Europe and the U.S.
EngelhardÂs selective catalytic reduction (SCR) technology is one of several platforms it has developed to meet growing demand spurred by more stringent regulations. The new technology is now being used in the production of a European truck model. The SCR catalyst can be integrated into an existing truck chassis using technology adapted from catalytic converters on passenger cars.
Euro 4 standards, which call for a 30% reduction of emissions of nitrogen oxides from heavy-duty diesel vehicles, began phasing in last year and take effect for all models in Europe this year. Euro 5 standards, now under discussion for implementation in 2008 and 2009, are expected to require an additional 40% reduction in such emissions.
Engelhard, a surface and materials science company, recently rejected an unsolicited takeover bid from GermanyÂs BASF. Shares of the company gained $0.24 to $40.39 in afternoon trading.
