how a catalytic converter works

Exhaust Systems & Repair

Catalytic Converter

Catalytic converters change harmful substances in a car’s exhaust gasses, such as carbon monoxide, nitric oxide, nitrogen dioxide and hydrocarbons, into less harmful substances like carbon dioxide and water vapour by means of chemical reactions. Precious metals like palladium, rhodium and platinum are commonly used as the catalyst and these have an intrinsic value that means they’re worth salvaging and recycling when the car is scrapped.

Catalytic Converter Care

  1. Always use the correct fuel and oil for your car.
  2. Never attempt to bump or tow start your car. This causes unburned fuel to be injected into the catalytic converter which can make the monolith overheat and melt.
  3. Have your car regularly serviced to the vehicle manufacturers’ specifications.
  4. Never use a fuel additive without first reading the instructions to find out if it is suitable for use with a catalytic converter.
