For example, high cylinder temperatures lead to the formation of nitrogen oxides NO x , and poor combustion leads to the formation of carbon monoxide CO and unburned fuel HC , which means these harmful and toxic compounds can make their way into the air. Air-fuel ratio sensor feedback and exhaust gas recirculation can mitigate some of the inefficiencies of real-world combustion, but not all. The catalytic converter is the last defense before engine exhaust escapes into the world.
It enables specialized chemical reactions, using heat and rare earth metals such as platinum, palladium and rhodium to combine unwanted emissions into safer compounds:. This helps get them up to operating temperature sooner, reducing or eliminating undesirable emissions.
Many believe catalytic converters reduce performance and efficiency. If you are at all concerned about the performance of your catalytic converter, call into your nearest Kwik Fit for a free exhaust check. Book a free exhaust check. Another device that helps to reduce carbon emissions is the oxygen or lambda sensor. This monitors the percentage of oxygen present in exhaust gases and transmits information to the engine management system or electronic control unit ECU.
The oxygen sensor, catalytic converter and ECU all work together to help to achieve the lowest possible output of dangerous and polluting gases. Sometimes, a failed catalytic converter can be due to a fault in the engine management system or lambda sensor. Unsure where to find your tyre size? Click here for more information.

Kwik Fit has over centres across the UK including Northern Ireland, many of which are open 7 days a week for your convenience. We endeavour to ensure we are displaying the correct tyres for your vehicle. However, we recommend all customers check the tyre size printed on the side wall of their tyres before proceeding with a tyre purchase as occasionally discrepancies do occur.
By selecting the tyre sizes above and clicking 'Continue', you are indicating that you have checked your tyre sizes. Please note: Centres do not open until on bank holidays.
If choosing an appointment on a bank holiday please bring your vehicle to centre at rather than the as shown. Your tyre size can be found on the sidewall of your current tyre and is a sequence of numbers and letters. The first three digits. This displays the width of the tyre in millimetres. They will check local security cameras and work to see if they can help catch the person who stole your converter. Additionally, a police report may be essential to your insurance coverage.
Depending on your coverage, your car insurance may cover your catalytic converter replacement. You can contact your insurance agent to see what your options are and whether or not you are covered. Finally, you should bring your vehicle to a mechanic for service. An expert can discuss your repair options with you and prevent you from driving without your catalytic converter.
The answer is both yes and no. Technically, a car can function without a catalytic converter. However, this is not a sustainable long-term option. Here are some of the troubles you will face when driving without a catalytic converter. The first sign of a stolen catalytic converter is incredibly loud vehicle noises.
You will find that when driving without your catalytic converter, it will sound like your vehicle is roaring—especially when starting or giving it gas. As your exhaust goes unregulated, your vehicle will drive more roughly.
Your engine usually forces your exhaust through your catalytic converter. Without this component in place, this forceful exhaust push will lead to jarring, uneven acceleration. Without your catalytic converter, you will fail both your NC safety inspection and your NC emissions inspection. Diesel cars typically have special catalytic converters to cope with the specific emissions from compression ignition diesel engines.
These Diesel Oxidation Catalyst units are routinely paired with additional exhaust treatment technologies such as exhaust gas recirculation, Diesel Particulate Filters to trap soot and Selective Catalytic Reduction which uses injections of AdBlue urea solution to remove NOx.
Reports suggest that the growth could be attributed to supply chain issues which have made it harder for dealers to secure replacement catalytic converters through official channels, creating a black market. Historically, however, the greatest driver of thefts has been the overseas markets for the precious metals inside the units.
Catalytic converters stolen in the UK are often illegally transported abroad and the metals recycled. While thefts of catalytic converters are still rare, there are some simple steps you can take to protect your vehicle Catalytic converters have been around since the 19th century when metal cylinders containing filters coated in platinum, Iridium and palladium were fitted to early French motor cars in an attempt to clean up the smoke coming out of their exhausts.
