Catalytic Converter


Catalytic Converter

The catalytic converter is a vital part of your vehicle emissions control system. Its job is to reduce toxic air by converting harmful pollutants into less harmful emissions, such as water, carbon dioxide and nitrogen.

What is a Catalytic Converter and how does it work

How Does it Work?

  • In the catalytic converter, there are two different types of catalysts: a reduction catalyst and an oxidation catalyst.
  • The catalytic converter works with your vehicle’s Powertrain Control Module (PCM) and other emissions control devices.
  • It has no moving parts, and is designed to last the life of your car.

How is it Made?

  • Stainless steel body
  • Monolithic free-fl owing substrate
  • Body and pipe heat shields
  • Catalyst cushioning mat
  • Oxygen sensors

Why Does it Fail?

  • Overheated, melted or broken converters.
  • Coated or oil-fouled substrate
  • Structural damage from corrosion, thermal shock, metal fatigue, stripped oxygen sensor threads or fl ex pipe failure

What are the Symptoms of Failure?

  • No acceleration when gas pedal pushed
  • Drop in gas mileage
  • Engine quits after a few minutes

What are the Implications of Failure?

  • Your vehicle will stall out and be unable to drive, due to inevitable engine failure.
