Your catalytic converter is an important part of the exhaust system on your INFINITI G37. It takes the pollutants created during the combustion process and converts them into less harmful elements. That results in air that's better for you, your passengers, and the environment in general.

How Catalytic Converters Work

The majority of catalytic converters work in a three-stage process. The first stage involves noxious engine byproducts passing through a reduction catalyst, like radium and platinum, that breaks down the compounds into less harmful compounds. Then an oxidation catalyst, usually made of palladium and platinum, gets to work. The result? Toxic molecules are separated into nitrogen and oxygen, with the oxygen allowed to continue on through the system. The process itself consumes both carbon monoxide and hydrocarbons, leaving behind little more than carbon dioxide and water vapors. The final stage involves the engine. The oxygen sensor in your engine measures the amount of oxygen in your exhaust system. As the oxygen levels change, the amount of fuel injected into the engine chambers grows or lessens as needed. That keeps the pollutant levels properly balanced, as mandated by the Environmental Protection Agency (EPA).

How to Spot a Bad Catalytic Converter

Normally, you can expect your catalytic converter to last for up to 10 years. However, you'll need to act quickly when it begins to fail, or else you'll risk both engine trouble and excessive environmental pollution. Signs of trouble include:

  • Excessive heat coming from under your car
  • You notice a sulfuric smell in the air
  • The exhaust makes rattling noises
  • Worsening engine performance
