Catalytic converters, V6

/ 9-5 (9600) / 2003 / 2. Engine / Exhaust emission control system, diesel / Technical description / Catalytic converters, V6

Two catalytic converters are used to reduce exhaust emissions. They can oxidise hydrocarbons (HC) and carbon monoxide (CO) to carbon dioxide (CO ₂ ) and water (H ₂ O). The catalytic converters can also help to oxidise some of the particles that are formed in the exhaust gases emitted by diesel engines.

A catalytic converter comprises a ceramic substrate (monolith) with a porous layer to increase the active surface. This layer contains microscopic particles of the catalyst platinum (Pt).
