The 2 Leading Causes of Direct Fit Catalytic Converter Failure
In order to protect their environment, various countries across the In order to protect their environment, various countries across the world have enacted laws requiring owners of motor vehicles to fit them with catalytic converter. Without it, your vehicle is likely to pollute the environment. In addition to converting harmful gases to forms which are safe to the environment, a direct fit catalytic converter also does a good job for your engine. The leading causes of cat converter failure: The leading causes of cat converter failure: Catalytic poisoning and clogging are the two major factors which may cause the direct fit catalytic converter to fail. Road damage and fracture of the unit may also cause it to fail.
Clogging: Clogging: Clogging is mostly caused by melting ceramics. The exhaust system of your car handles very hot gases which may cause heating up the cat converter. When there is rich mix of air and fuel, the unburned fuel may pass through exhaust system. If any fuel gets past the combustion chamber unburned and enters the exhaust system, it may ignite upon reaching the catalytic converter. If the unit is heated beyond its maximum operating temperature, there may be total or partial meltdown especially if the catalyst is made of ceramic. In addition to the mixing of air and fuel, malfunctioning check valve, faulty fuel injector, sticking float, faulty oxygen sensor, corroded spark wires or plugs and incorrect timing. Carbon deposits can also cause clogging of the car exhaust system. In some cases, through various leaks, antifreeze may get in to the car exhaust system. When this happens, there may be ignition of the invasive chemicals leaving sooty residue which may cause blockage of normal flow of gases. The blockage causes backpressure increase and there may be backing up of the heat and exhaust in to the vehicle engine compartment. This will cause overheated engine components and loss of power.
Catalytic poisoning: Catalytic poisoning: Catalytic poisoning can happen when the chemicals that cause clogging get in your car’s direct fit catalytic converter. The interaction between these chemicals and the catalyst chemicals may cause change of the latter. This change will mean the cat converter can no longer convert the harmful exhaust gases into harmless nitrogen gas, water vapour and carbon dioxide.
