Catalytic Converter

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.
  • Catalytic Converter (CAT)

    The catalytic converter is a device installed in the exhaust system to significantly reduce the emission levels of hydrocarbons (HC), carbon monoxide (CO), and in the case of most newer catalytic converters, oxides of nitrogen (NOx). CO and HC reduction CATs are called Two Way CATs, and CATs which reduce all three emissions are called Three-Way CATs. Your vehicle's Underhood Emissions label can provide you with information regarding the type and requirement of this component.

    If your vehicle requires a catalytic converter it must be present, installed and functioning properly. 95% of vehicles on the road in California are required to be equipped with a CAT.

  • For the Smog Test: During the smog inspection the smog technician will visually inspect the CAT for presence and proper connection. Should your vehicle fail the smog test the CAT may be suspect. A vehicle's CAT usually becomes plugged after a material breakdown within it normally due high exhaust temperatures and rich fuel. After first inspecting the fuel and ignition systems, an intrusive CAT test and Back Pressure/Vacuum test may be performed. These tests will determine whether the CAT is plugged or not. The important thing here is this... if in fact the CAT is damaged, it is important to insure a pre-existing problem is not the culprit. You don't want to damage the new CAT. A CAT melt down usually occurs due to high CO (Rich Fuel), old age, and extreme heat. It is recommend to suspect the CAT after a complete emissions systems diagnosis has been performed.
  • In Case of Failure: The most accurate way to find out if your vehicle's CAT is working efficiently is by using an exhaust gas analyzer. Unfortunately this tool is fairly expensive and not designed for home use. You must visit a local smog station and have the smog technician inspect the CAT via the shop's gas analyzer. Symptoms of defective Catalytic Converters may be any of the following:
    • Symptom: Loss of engine power over 15-20 miles per hour.
      Fault: CAT is plugged up and restricting exhaust flow.
    • Symptom: Strong sulfur smell from otherwise efficient running engine.
      Fault: Catalyst not completing the burning process properly.
    • Symptom: Rattle being heard from CAT during idle and acceleration.
      Fault: Catalytic substrate broken down and possibly plugged.
    • Catalytic Converters
  • Operation: The CAT is a catalyst, it typically plays no part on how well your engine runs. The catalytic converter only begins working after exhaust has exited the engine's combustion chambers. When hot exhaust gases are forced through the catalytic converter, they contact the catalyst substrate. This causes a rapid increase in temperature, thus burning the exhaust gases even hotter and more thoroughly, ultimately reducing emissions.

    In the Three Way CAT, once the HC and CO reduction has occurred by extreme heating, a NOx reduction substrate separates the harmful pollutant known as nitrogen oxides into nitrogen and oxygen.

    Catalysts are designed to function for a limited time, and require replacement. How long a vehicles CAT will last depends on how completely the engine burns fuel before presenting it the to the CAT and also on the quality of the CAT. Factory CATs should normally last 7 to 10 years. Aftermarket CATs should work for at least half that. We see CAT failures most often in vehicles which have been poorly maintained and which have produced high emissions in more then one category.

  • Catalytic Converters
  • Location: The catalytic converter exterior is usually made of stainless steel. The CAT looks very similar to a muffler except it contains a catalyst substrate within and is normally located in the exhaust system before the muffler and after the exhaust manifold. Most often you will located the CAT underneath your vehicle towards the center of the exhaust system. On certain 4 and 6 cylinder model engines you will see the CAT directly after the exhaust manifold. On these model vehicles the CAT and exhaust manifold may be one unit
  • While the emission systems in today's vehicles consist of many complex and integrated parts, we have designed this site to be both informative and educational. Catalytic converters typically do not fail on their own. Thereis usually an underlying cause that results in catalytic converter failure and it is important to find that cause before replacing the catalytic converter to prevent future problems.
