Over 250 million highway vehicles rely on internal combustion engines (ICE) in the US. ICE engines offer excellent durability, but they can also create harmful emissions. But the good news is there is an auto part that combats emissions.
The catalytic converter. Without one, your vehicle can produce too many fuel emissions. Emissions include hydrocarbons and carbon monoxide.
Usually, catalytic converters last over 100,000 miles or the lifetime of your vehicle. However, there are cases when there is catalytic converter failure. Signs of catalytic failure include reduced fuel economy and a reduction in engine performance.
But what causes catalytic converter failure? Read on to learn the causes of converter failure so you can prevent it from happening.
Neglecting Engine Tune-Ups
If a car is not operating to its specifications, wear and tear damage car components. Any issues with car parts, such as the engine timing, can impact the catalytic converter. Over time this can lead to a catalytic converter failure.
Do not neglect engine tune-ups. If you need to replace parts such as the exhaust, invest in parts that comply with emission standards and use up-to-date technology. Check out Magnaflow exhaust systems as an example.
Coolant or Oil in Exhaust System
Coolant or oil in the exhaust system can stop the catalytic converter from reducing harmful emissions. It can be caused by issues such as damaged gaskets or faulty valve seals. The exhaust flow gets blocked due to a build-up of carbon deposits.
Maintain the coolant system and keep an eye on oil levels. Do not ignore engine warning lights such as the coolant light or the service engine light.
Fuel in Exhaust System
Another sign of an intake leak is a difference in the air-to-fuel ratio. If the ratio is not exact, there are issues, such as unburnt fuel entering the exhaust system. It will then ignite and overheat the catalytic converter. This leads to converter failure over time.
There are different causes of fuel in the exhaust system, such as oxygen sensor failure. Also, look out for signs of fuel injector leakage, such as hard starts and gasoline smells. Also, look out for exhaust leaks such as odd vibrations and loud noises.
Deteriorated Spark Plug or Wires
Spark plugs that are misfiring or not firing at all can also lead to fuel entering the converter. Check spark plugs and the wires regularly. If they appear damaged or cracked, replace them to reduce the risk of converter failure.
Prevent Catalytic Converter Failure
The sooner you detect signs of converter failure, the sooner you can take action. You can prevent catalytic converter failure with early detection. And you can potentially save your vehicle from irreversible damage.
Have regular vehicle maintenance and servicing. Make sure to use the appropriate antifreeze for bmw, as using the wrong type can damage the engine and potentially lead to issues with the catalytic converter. And if you notice anything abnormal with your vehicle, get it checked out. Even if you need a new catalytic converter, make sure the source of the problem is fixed, so it does not happen again!
