Catalytic converters are generally located near to the exhaust manifold and remove pollutants from the exhaust fumes the engine produces. If the substrate is intact, the only maintenance that a catalytic converter requires is a cleaning. At Full Circle Vehicle Service and Repair Specialists, high Wycombe, we’re able to install this system, provide the cleaner and repair any blockages if the substrate breaks.
In any car and regardless of what type of fuel is used in the vehicle (petrol, diesel or LPG) the catalytic converter removes pollutants from the engine’s exhaust fumes before they are released through the exhaust pipe. The part receives its name due to the catalyst inside the system which creates the chemical reaction. The catalyst is normally a small amount of a precious metal such as rhodium, platinum or palladium.
If your vehicle has a malfunctioning catalytic converter, your car should not be on the road as vehicle manufacturers are legally required to minimise pollutants being emitted into the environment. The harmful pollutants that are removed from exhaust fumes don’t include carbon emissions but do include toxins such as carbon monoxide, unburned hydrocarbons, and nitrogen oxides.
If the substrate remains intact, a catalytic converter will only fail if something goes through the system which shouldn’t – for example, oil, coolants, petrol, certain engine cleaners or anti-wear additives. Over time, there may be a buildup of carbon deposits on the surface of the catalytic converter. These signs won’t be noticeable to you as the driver, except for a sulfurous smell coming from the exhaust. If the substrate breaks, it can cause a blockage in the exhaust manifold and a substantial loss of power, which is why servicing is so important.
Modern cars these days have oxygen sensors before and after the catalytic converter to pick up any irregularities in the exhaust fumes, and if anything is amiss, the check engine light will remain on. In this case, all you need to do is buy a cleaning agent and pour it directly into a tank of petrol and drive the vehicle as per usual. The cleaner will break down deposits in the catalytic converter and the fuel system. However, it’s always best to check your converter with a professional, just in case something more serious isn’t amiss.
