A catalytic converter is an air pollution control device which transforms toxic gases and pollutants in an internal combustion engine’s exhaust gas into less toxic gases through activating an entire redox reaction between oxygen and the pollutants. The catalyst is typically an active carbon that absorbs the poisonous gases before the exhaust gases enter the filter and combustion chamber. Since the carbon absorbs toxic substances, less poisonous emissions are emitted. This is the foundation of the majority of modern vehicle emission controls and pollution sensors, too.
Manufacturers continue to use catalytic converters to provide an alternative to traditional exhaust systems. However catalytic converters recently attracted lots of attention in the media as a possible cause of cancer. Before deciding whether to include an catalytic convert in your vehicle, it is important to understand the way they work. There are two major components of a catalytic converter assembly that are the catalyst exhaust and the catalytic convertor assembly. The catalyst mass is the catalyst that triggers the reaction between pollutants and engine exhaust gases. It is part of the catalytic converter assembly.
The catalytic converter itself will include an aluminum plate and a stainless steel or chrome manifold that is plated. The plate is typically made from a high density steel, however other metals such as titanium and cast iron are also utilized. The catalyst for the conversion reaction is the plate. It is usually an oxide of ferricoxid. If the catalytic converter isn’t replaced, it could cause a significant change to your emissions inspection results.
You must make sure that your catalytic converters function correctly when you conduct emissions inspections. If your vehicle is exhibiting a high level of carbon monoxide, the converter could react with the exhaust gas and produce carbon dioxide. To determine if this is the case, you should conduct an annual inspection and note down the times that carbon monoxide and the catalytic converter were found. If there is a significant build up of carbon monoxide, it should be evident that the converter must be replaced.
Properly venting exhaust gases and the catalytic converter is crucial to ensure clean air from the outside. You should immediately suspect a catalytic conversion leak if either of the components is leaking. Catalytic converter leaks can result in dangerous levels of toxic substances, like carbon monoxide and other toxins, in your exhaust system and engine. Catalytic converter leaks can result in significantly higher emissions rates and poor performance, making it important to immediately have these components replaced or repaired.
When you perform your annual maintenance on your vehicle, you need to also perform a diagnosis of the various issues with your vehicle. By identifying these components, you determine which parts, if any, are responsible for a slow or unreliable start and idle quality that is not optimal, excessive wear and tear on components like brakes and other engine components, and general poor performance. It is imperative to immediately take your car to a Synchrony repair shop if you observe any symptoms such as excessive noise, vibration, and reduced performance. This is particularly important if symptoms occur at night, or when you feel the need to stop more frequently than normal. In this instance replacing the catalytic converter might not be only necessary but also the most affordable option.
The muffler needs to be checked first to determine if there are leaks within your exhaust system. If you hear a loud sound, you must take your vehicle to a Synchrony-certified technician for a check and replacement of your catalytic converter. The exhaust system consists of an catalytic converter, a muffler and a tailpipe. Each component is essential for an efficient and safe exhaust system. If one or more of these components fails the exhaust system won’t perform as it should. If you notice a decrease in your gas mileage or a decrease in horsepower, the catalytic convert must be replaced.
In most instances the catalytic converter needs to be upgraded. If the catalytic converter has suffered significant erosion due to corrosion, a catalyst could be required that dissolves the crystal matrix. There are many synchrochemicals that are available for purchase, such as palladium and rhodium , as well as cobalt. They are made from palladium and platinum and offer the same catalytic reaction as the original platinum catalyst but without the price tag.
