Catalytic converters were invented as a means to save the environment from pollutants, keep our cities free of smog, and ensure our air stays fresh and breathable. Not only is this device legally mandated to be included in your fuel system, but it can also benefit you through improved fuel economy and increased horsepower. If you suspect your converter is going out, this list will offer you some hints to decide if it’s time for an update.
1. Loud Noise Beneath the Vehicle
The purpose of the converter is to trap harmful gases from
your exhaust and use a catalyst, usually a precious metal, to change the
molecule into a harmless form. Along with the catalyst, this is accomplished
through a ceramic base and layers of mesh. When degraded, the mesh can fall
apart and bounce around within the metal casing, resulting in a rattling sound.
This noise will become especially apparent as the engine turns over.
If the noise is exceptionally loud you may have lost your converter completely.
A situation like this may be accompanied by a sulfur smell and will sound like
a roar when you accelerate the engine.
2. The Engine Light Turns On
Having the engine light turn on can mean a variety of
issues, and a damaged converter may be one of them. When the device’s film
becomes clogged, air is unable to pass through the engine as it should. This
results in an incorrect mixture of fuel and air, which may be picked up by your
ratio and oxygen sensor. A mechanic should be able to run the error codes and
let you know if your engine light relates to your airflow.
3. Decreased Performance
Engines are designed to run with an ideal mixture of air to fuel, and when the converter is clogged or damaged that ratio will be incorrectly balanced. When you attempt to accelerate, gas will be added to the engine but have no air to actually burn with it, resulting in more trips to the pump and more money wasted.
These days converters can improve your fuel economy and horsepower beyond serving their usual function. A high-flow converter contains more of the precious material than the basic version as well as a wider mesh film, resulting in faster conversion of the pollutants with an increase in the volume of air your engine can pass.
If you want to get the most out of your vehicle you’re going to want a converter that is functioning at its best. Keeping this device clean and operational ensures the safety of everyone on the road.
