For diesel emission control technologies, reduction efficiencies of Particulate Matter (PM) control systems have been traditionally reported based on mass-based criteria. However, particle number-based criteria are now receiving increased attention.

The continuously regenerating trap (CRT) is a diesel exhaust emission control that removes nearly all diesel particulate matter on a mass basis, but under some circumstances oxidation of sulfur leads to the formation of nanoparticles. The objective o

NO x adsorber catalysts (NACs) can be applied in lean-burn gasoline and diesel engines to reduce NO x emissions. Typically NACs are formulated using platinum as an oxidation catalyst, barium as a storage component and rhodium for NO x reduction. Ther

The time taken for an exhaust emission-control catalyst to reach its operating temperature for hydrocarbon oxidation is a major barrier to achieving ultra-low emissions from vehicles. A new approach for achieving rapid catalyst light-off from a vehic
