The main reason why people face problems with the catalytic converters is that they are not maintained properly. In order to keep the catalytic converter free from trouble you need to keep in mind certain important factors. It is important for you to be able to identify the defective catalytic converter symptoms if you want to prevent it from malfunctioning. There are various ways by signs, by which you can make out that your car’s catalytic converter is on the verge of breaking down. Some of the common symptoms of defective catalytic converter are briefly described below.

 

The main function of a catalytic converter, which lies in-between your car’s engine and exhaust is to remove harmful pollutants from the exhaust gases. The interior of this machine is honeycombed and is made up of rhodium, platinum and palladium coated ceramic compositions. This device is capable of changing air pollutants like nitrogen oxides into oxygen and nitrogen and carbon monoxide into carbon dioxide. It also has the power to change detrimental hydrocarbons into un-burnt gas, prior to discharging the emissions. The most effortlessly detectable sign is the deafening noise, which is produced due to the leaking of exhaust gases from a malfunctioning catalytic converter shell. The damage might be caused owing to an undercarriage event like a pebble bouncing off the catalytic converter. Few of the symptoms that can help you to check your catalytic converter are:

 

The collision of stones might fracture the shell’s delicate ceramic internal structures, which might produce a rattling noise.

 

Owing to decreased exhaust backpressure, the performance of the engine might get hampered.

 

Reduced engine efficiency, with regards to fuel consumption.

 

Minor reply from the car engine with regard to acceleration, when the gas pedal is pushed

 

Warning signal sent from the car’s oxygen feeler that keeps an eye on the working of the catalytic converter.

 

A fully functioning engine going silent for no obvious reason

 

Catalytic Converter SymptomsThe device operates at a temperature ranging between 1,200oF and 1,600oF. If there is a rise in the internal temperature then it can cause drastic damage to the performance of the vehicle as well as can harm the catalytic converter. Some of the most familiar causes of a catalytic converter malfunctioning are as follows;

 

Firstly, un-burnt fuel catching fire inside the catalytic converter as well as outside the car’s combustion chamber can create problems. The enormous heat produced by this event can lead to the meltdown of the converter, which in turn might cause obstruction within the exhaust.

 

Secondly, chemical like antifreeze or burnt oil produces heavy particles of carbon, which when goes into the catalytic converter, covers the platinum and palladium coated ceramic structures thus interrupting their functioning. These heavy carbon particles also jam the pores of the catalytic converter by means of which the unpolluted exhaust gases flow out and thus leads to severe technical problems.
