More Information
Summary:An apparatus is disclosed. The apparatus comprises a lean-burn internal combustion engine, engine management means and an exhaust system for treating exhaust gas of the engine. The exhaust system comprises a first oxidation catalyst disposed on a first honeycomb monolith substrate. The first oxidation catalyst comprises platinum supported on a first metal oxide support comprising at least one reducible oxide, and is substantially free of alkali metals and alkaline earth metals. The engine management means is arranged, when in use, intermittently to modulate the lambda composition of the exhaust gas entering the first oxidation catalyst to a rich lambda composition.
