ABSTRACT:
A system including a compression ignition engine operable in a first, normal running mode and operable in a second mode to produce an exhaust gas having an increased level of carbon monoxide (CO) relative to the exhaust gas produced in the first mode. The system, when in use, can switch engine operation between the two modes, and the system includes an exhaust system. The exhaust system includes a supported palladium (Pd) catalyst associated with at least one base metal promoter and an optionally supported platinum (Pt) catalyst associated with and/or downstream of the Pd catalyst wherein CO is oxidised by the supported Pd catalyst during second mode operation.
