The vehicle's exhaust system includes a catalytic converter. Its purpose is to remove toxic substances from the exhaust. Under the influence of high temperatures, chemical reactions with the platinum group metals take place inside of it. After passing through the catalytic converter, the exhaust gases are cleaner. This part is appreciated even after its failure, and many dealers on the website https://autocatalystmarket.com/gb/en offer to buy out old catalytic converters under favorable conditions.
Causes Of Catalytic Converter Malfunctions
According to the manufacturers, the catalytic converter can serve for about 93,000 miles.
The leading cause of malfunctions is the burnout of the metal layer that covers the honeycomb. The use of low-quality fuel accelerates the burnout of the part. Often, to increase the octane number of gasoline, lead is added to it, and so the load on the catalytic converter becomes more intense. If we talk about diesel fuel, then the vehicle users may accelerate the failure if they use various additives in winter.
Sometimes the part can fail due to a faulty engine. If the ignition is set incorrectly and there are problems in the fuel feed system, the catalytic layer burns out faster than usual.
Symptoms Of The Converter's Failure
Catalytic converter malfunctions are challenging to miss. The vehicle starts showing the following symptoms:
The "Check Engine" indicator lights up on the dashboard - this means a lambda probe alerts of the error in the engine. Diagnostics with a scanner will help to confirm that the reason is in the catalytic converter.
The engine loses performance - the vehicle accelerates worse, its starts to twitch and misfire.
There is a rumbling sound under the bottom of the car - particles of destroyed ceramic honeycomb hit against the converter's walls. They are affected by the flow of gases and centrifugal forces.
Gases come out of the muffler with a weak or uneven pressure - the cause is the destroyed honeycomb of the catalytic converter.
At the first sign of failure, the part should be diagnosed. First, it is recommended to conduct a visual inspection for mechanical damage. The damage inside the case can be detected with the help of computer diagnostics, which is carried out by technician specialists at the service shops.
Replacement Options For Catalytic Converters
The most reliable option for replacing the catalytic converter will be the purchase of the original part. Such a part will serve for a long time while performing its job perfectly. In some cases, this way of solving the problem can be a significant expenditure for the budget. Then you can find and install a versatile part.
And for those who do not want to search for a new catalytic converter time and again, manufacturers offer a flame arrester. This method involves the complete removal of the catalytic converter from the vehicle. But in this case, re-flashing of the onboard computer will be required.
Replacement options may be different, and each vehicle owner chooses what the best in each case is.
