Catalytic Converter

When the vehicle engine burns fuel, it produces gases which are high in toxin. A catalytic converter is a device used to reduce the toxicity of the exhausts.

Types of Catalytic Converter
There are two main types of structures used in catalytic converters:

• Honeycomb
• Ceramic Beads

Characteristics of Catalytic Converter

• It is situated between the exhaust manifold and the silencer.
• There is an oxygen sensor mounted in front of the catalytic converter.
• Most catalytic converters have precious metals contained in their lining such as platinum, aluminum oxide and palladium which transform harmful gases into non-toxic materials.

Functions of Catalytic Converter

• Reduction of nitrogen oxides to nitrogen and oxygen
• Oxidation of carbon monoxide to carbon dioxide
• Oxidation of unburnt non-methane hydrocarbons to carbon dioxide and water

Maintenance of Catalytic Converter

• The converter body and end tubes should be checked periodically to see if they are broken or rusted.
• It should be checked for a rattle, if it does not rattle, the pellets may have melted together or fallen out.
