Catalytic Converter Symptoms

Catalytic Converter Symptoms

catalytic converter is used in vehicles to reduce the level of impurities arising from their emissions. It is quite possible for the converter to get destroyed because of external as well as internal factors ranging from accidents, inappropriate fittings and mishandling. Here are some of the most common catalytic converter symptoms for their failure.

Power Loss

Power loss is one of the most common catalytic converter symptoms. This occurs due to thermal failure and overheating. This happens when a huge amount of unused or raw fuel is in contact with the catalytic converter and burning takes place inside the converter. This way the fuel is restricted from reaching the engine. Due to this kind of leakage, excessive fuel could also result in heating the converter, which would lead to burning of ceramic monolith. The monolith is an integral part of the converter.

High Levels of Emissions

High levels of emission occur when failure of converter occurs due to plugged or contaminated substrates. This creates a disproportion in the levels of fuel mixture. Whenever anti freeze, radiator sealant or oil gets into contact with the exhaust flow, the mixture of air becomes higher in its level, and this in turn results in deposits of carbon in the exhaust. Whenever the accelerator is pushed and engine is turned on, the vehicle begins to emit excessive amount of nitrogen oxide, carbon monoxides and hydrocarbons.

Bad Odor

This is another important catalytic converter symptom for failure. This is caused due to the increase in the heat in the ceramic monolith. This happens because of fuel mixture or wrong fuel getting into contact with the converter. The inappropriate mixture of fuel causes increase in content of hydrogen sulfide, when emission occurs. This results in the rotten egg odor.

Thermal Shock

Thermal shock results in ‘Rattling’ and its one of the main catalytic converter symptom. This happens when the converter is heated to his maximum capacity and then suddenly comes into contact with something cold like snow. The cooling agent in this case must be extremely low in temperature. The extreme temperature difference results in ceramic substrate cracking. On the account of this change, the converter housing then contracts. This results in the sound of rattling when the compact converter is contacted by any other substance.

Another symptom is lowering of performance levels due to several reasons. Be on the look for these symptoms and do what is necessary to get your converter back to the same condition.
