Understanding Catalytic Converters
Before we dive into maintenance, let’s gain a clear understanding of what a catalytic converter is and what it does. This knowledge will help you appreciate the importance of proper maintenance because you only keep what you know about.
A catalytic converter is an emission control device that converts toxic pollutants in exhaust gas into less harmful substances before they are released into the atmosphere.
They serve as eco-friendly warriors, tasked with converting harmful gases from your engine’s combustion process into less harmful substances before they exit the tailpipe.
They play a significant role in reducing air pollution and meeting emission standards, which are critical requirements for any car in some countries, such as Japan and the European Union.
The oxygen sensor transmits information from the catalyst to the electronic control unit, or power control module.
Understanding the role and indicators of a well-functioning or failing catalytic converter is crucial for proactive maintenance. Here are key signs to look out for:
| Indicator | Functioning Converter |
|---|---|
| Efficient Emissions Reduction | Reduced emissions of harmful pollutants in exhaust gases |
| Optimal Engine Performance | Consistent engine power and fuel efficiency |
When signs such as decreased fuel efficiency, sulfuric odor from exhaust, or rattling noise during startup are observed, it may indicate potential issues with the catalytic converter.
Various types of Catalytic Converters
It is vital to have a solid understanding of the two principal types of catalytic converters, which are two-way and three-way catalytic converters, in order to efficiently maintain your catalytic converter.
Catalytic converters that work both ways
These converters, also known as “oxidation” converters, primarily perform the following two tasks:
The equation 2CO + O2 = 2CO2 represents the formation of carbon dioxide from the oxidation of carbon monoxide.
Hydrocarbons undergo oxidation, producing carbon dioxide and water in the following ways: CxH2x+2 + [(3x+1)/2] O2 → xCO2 + (x+1) H2O
The Catalytic Converters That Are Three-Way
Since 1981, both the United States of America and Canada have utilized “three-way” catalytic converters in the pollution control systems of electric vehicles. Compared to other converters, these are more advanced and can perform three functions simultaneously:
Nitrogen oxides are reduced, resulting in nitrogen and oxygen. 2NOx → xO2 + N2
The equation 2CO + O2 = 2CO2 represents the formation of carbon dioxide from the oxidation of carbon monoxide.
Unburned hydrocarbons (HC) undergo oxidation, which results in the production of carbon dioxide and water. CxH2x+2 + [(3x+1)/2] O2 is equal to xCO2 plus (x+1) H2O.
In order to perform appropriate maintenance on your car, you must have a solid understanding of the type of catalytic converter that is installed in it.

This is especially important when traveling on underdeveloped roads.
step 2: regular cleaning
Despite its high efficiency in enhancing the converter’s function, catalytic converter cleaning is a maintenance step often overlooked.
We highly recommend cleaning your catalytic converter every time you change your oil.
Cleaning solutions designed specifically for catalytic converters can aid in the removal of carbon buildup.
To save money, you can take a different approach by following the outlined measures below.
Use the appropriate tools to remove the catalytic converter from your car. The next step is to fill a large bucket with a solution of dish soap and water until it is full.
After removing the catalytic converter, immerse it in the soapy solution and let it soak overnight.
Immediately after the soaking process, ensure the converter’s honeycomb structure is clear of any debris.
You are able to proceed with the reinstallation of the catalytic converter and the reassembling of your car’s exhaust system, provided that it is clean.
Step 3: Determining Which Fuel to Use
The type of fuel you use has a direct impact on the health of your catalytic converter, as well as the amount of time it will last.
High-quality fuels, particularly those with a higher octane rating, are the ones that we recommend.
This is because high-quality fuels typically contain superior detergents that can help prevent the accumulation of impurities in the catalytic converter.
When you use fuel of poor quality, carbon can accumulate in the catalytic converter, causing it to perform less effectively.
On the other hand, when you use premium fuel, you can not only increase the life of your catalytic converter but also improve your car’s overall efficiency.
