Title: Catalytic convertor on a mk2?
Post by: Mk2George on 28 November 2007, 21:00

A catalytic converter is a device that uses a catalyst to convert three harmful compounds in car exhaust into harmless compounds.

The three harmful compounds are:

    * Hydrocarbons (in the form of unburned gasoline)
    * Carbon monoxide (formed by the combustion of gasoline)
    * Nitrogen oxides (created when the heat in the engine forces nitrogen in the air to combine with oxygen)

Carbon monoxide is a poison for any air-breathing animal. Nitrogen oxides lead to smog and acid rain, and hydrocarbons produce smog.

In a catalytic converter, the catalyst (in the form of platinum and palladium) is coated onto a ceramic honeycomb or ceramic beads that are housed in a muffler-like package attached to the exhaust pipe. The catalyst helps to convert carbon monoxide into carbon dioxide. It converts the hydrocarbons into carbon dioxide and water. It also converts the nitrogen oxides back into nitrogen and oxygen.

As far as I know it is, that's a US website so that might be why there is some confusion. All UK Cars after 92 will need one for an MOT iirc.

cats were optional on MK2s, but in the UK they wernt often fitted because not only were they very expensive, it made the car slower :grin:
