Be sure to flush the unit from both ends. Another way to clean the catalytic converter is to soak it overnight in a combination of hot water and degreaser or laundry detergent. This process takes longer but is necessary to dissolve the deposits clogging up your catalytic converter. After washing or soaking, be sure to dry the catalytic converter completely before reinstalling. Sometimes, the catalytic converter absolutely needs to be replaced like if it's broken internally or melted down.
If you have to replace your catalytic converter, make sure it lasts as long as possible with these tips. Actively scan device characteristics for identification. Use precise geolocation data.

They have a two-way converter DOC to oxidize carbon monoxide. Still, They are also fitted with an SCR reduction catalyst to reduce nitric oxide, and nitrogen dioxide emissions together referred to as NOx. The catalytic converter carries out an essential function of converting harmful compounds into non-toxic products. The interior of its metal casing contains two ceramic blocks with thousands of micro-cellular units resembling a honeycomb.
The ceramic blocks are coated with metals such as palladium and platinum. Due to its close location to the engine, the catalytic converter usually heats up and catalyzes chemical reactions that convert toxic gases to harmless byproducts before their emission into the atmosphere.
They catalyze the reduction of carbon monoxide to water and carbon using metal catalysts. They also break down volatile byproducts and hydrocarbons into less harmful chemicals preventing the emission of harmful gases. However, different from petrol-based catalytic converters, the diesel-based cat has no rhodium, more so, the diesel cat comes with an attached diesel particulate filter DPF to eliminate the particulate matter absent in petrol-based petrol catalytic converter.
As the reductant and exhaust go over the SCR catalyst, a chemical reaction occurs, converting NOx emissions to water and nitrogen. In comparison, the closed-loop system found on stationary engines can achieve an effectiveness of more than 95 percent. SCR also reduces hydrocarbon emissions by about eight percent. The use of low sulfur fuel can improve its performance. Diesel engines converters are also uniquely designed to work with diesel engines to target and filter particulates.

What Is Inside a Catalytic Converter? There are two main types of catalysts that might be featured in a car: Reduction catalysts: Help reduce nitrogen oxide pollution by removing oxygen. Nitrogen oxides are broken up into nitrogen and oxygen gases, which on their own are harmless.
Oxidation catalysts: Used to change carbon monoxide into carbon dioxide through an opposite process of adding oxygen. Types of Catalytic Converters As mentioned before, there are two primary catalysts — reduction and oxidation — that can be used within an exhaust system to handle specific gases. There are two primary kinds of catalytic converters: Two-way: The two-way catalytic converter was present on vehicles in the United States until They only have oxidation catalysts, which help change carbon monoxide to carbon dioxide.
Hydrocarbons which is unburned and partially burned fuel are changed to carbon dioxide and water. Three-way: Since , the three-way catalytic converter has been used.
This performs the same as the two-way converter with the addition of a reduction catalyst. As stated earlier, this is used to change nitrogen oxides to nitrogen and oxygen gases.
How to Prevent Catalytic Converter Theft Catalytic converters are often the target of thieves because the part contains valuable precious metals. Regardless of the type of vehicle you have, there are some steps you can take to help prevent theft: Park in well-lighted areas close to building entrances if a secure garage is unavailable.
Weld the catalytic converter to the vehicle frame, which can make it harder to remove. Consider buying an aftermarket part similar to a metal cage that can be installed to cover the converter. Install a car alarm with a vibration alert sensor. Engrave your vehicle identification number VIN to the converter, which can help make selling the part harder and help alert you if your converter is stolen. Frequently Asked Questions Why do people steal catalytic converters? How much platinum is in a catalytic converter?
What about palladium or rhodium? How much is a catalytic converter worth? Signs of Catalytic Converter Issues So what happens when a catalytic converter goes bad?
Some examples to watch out for include: Declining fuel efficiency: If a catalytic converter becomes clogged, it can reduce the amount of airflow through your engine. To compensate, your engine might start to burn more fuel than usual, resulting in a noticeable drop in fuel efficiency. Check warning light: A check engine light can indicate a range of things. However, there is a diagnostic system on cars manufactured after that will test the catalytic converter. If your converter is malfunctioning, the air-to-fuel ratio sensors might trigger the warning light to come on.
Smelling rotten eggs: The catalytic converter might experience internal damage that causes it to have a hard time converting exhaust gases.
