Patent abstract
An oxidation catalyst for a light-duty diesel vehicle comprising a first upstream part (2) and a second downstream part (3) of high heat capacity relative to the first part, each part comprising a substrate and a catalyst support coated thereon. With this arrangement the diesel catalyst can reach light-off temperature more quickly and retain sufficient heat to maintain light-off temperature for substantially longer than conventional diesel catalyst arrangements.
