We all try and do our bit for the environment, and surprisingly, our cars are fitted with various parts which try and do the same. Catalytic converters help to remove harmful gases from our exhaust system before they hit the air, which makes them a pretty useful component. It's good to keep your catalytic converter happy, as it's often checked over as part of your cars MOT. For best practice and to keep your vehicle in ideal condition, Many Autos recommends you have exhaust system checked at least twice a year for cracks, leaking joints, broken hangers, worn rubber mountings, corrosion, failed gaskets and other damage or wear. After we have completed your inspection, we will provide you with a written report and a quote for any work which is required. Over the years, car manufacturers have been trying to find ways to reduce the harmful pollutants produced by vehicles. In 1975 they came up with the catalytic converter – and this is now the most important part of a car’s emission control system. In 1993 it became the law in the UK for new cars to be sold with catalytic converters in order to meet European emissions standards, now cars are often produced with multiple cats as standards become more stringent. The catalytic converter is beneficial not just to the environment but also to your car’s performance. However, it’s essential to have it checked regularly as faulty cats are expensive to repair. The Lambda sensor works in conjunction with the catalytic converter to determine how much oxygen the car is using, so this also should be checked if you have an exhaust issue.
A plugged catalytic converter will only in extreme cases prevent you from driving your car. You can usually drive your car indefinitely with a partially plugged converter, though you will see a drop-in performance.
Catalytic converters change harmful emissions into harmless gas, and they need to be replaced only if they become clogged or otherwise damaged and can't function properly. They're expensive to replace, so they aren't considered a regular maintenance item. A damaged “cat” should trigger a Check Engine light.
Misfire from bad spark plugs/wires, or an excessively rich fuel mixture are the leading causes. Once a catalytic converter has gone bad, you'll probably get a check engine light, and fail emissions tests. As things get worse, you can expect a bad smell, loss of power, poor acceleration, engine stalling, etc.
Here are five signs that something may be wrong with your catalytic converter.
Bad spark plugs or damaged exhaust valves can also destroy a catalytic converter. However, if your converter is completely clogged, your engine will quickly fail because of all the exhaust back pressure.
A bad or failing catalytic converter can also cause an illuminated Check engine Light. The oxygen and air fuel ratio sensors that modern vehicles are designed with monitor the efficiency of the catalytic converter by monitoring the gas levels in the exhaust.
The most common cause is unburned fuel entering the catalytic converter. Also, faulty spark plugs and leads will cause the engine to misfire and ruin the catalytic converter. The excess fuel will enter the exhaust system and cause it to overheat.
Unless the converter is clogged and physically prevents the exhaust gases from escaping, it cannot directly block the engine. A bad cat could result in the engine cutting off altogether, but it's not likely, because the owner usually gets the bad cat replaced before it gets to the point the engine won't run at all..
It can also burn holes in exhaust system components and destroy your vehicle's catalytic converter. And, of course, it can also be a fire hazard if the vehicle is parked over anything that is flammable.
Sometimes, the worst part of getting your car fixed is having to bring it to the garage. We are therefore happy to offer our customers a free collection and delivery service If you prearrange a collection, we will pick your car up from your home or place of work and drive it to our premises, carry out all the necessary work (having consulted you) and deliver it back to you at the end of the day.
