Going beyond Bin 5 and Euro 5

An early look at some of the emissions-control and aftertreatment technologies and tools aimed at helping automakers meet future U.S. and European regulations.

Improving vehicle fuel efficiency, with its direct impact on reducing CO₂ emissions, has become the battle cry of powertrain engineers worldwide. But that doesn't mean efforts to reduce oxides of nitrogen (NOx) and other “traditional” greenhouse gases, as well as exhaust particulates, have abated.

On the contrary, R&D teams are looking beyond the current regulatory horizon to develop new emissions-control and exhaust aftertreatment technologies for the 2010 decade.
