The exhaust gas neutralizer plays an important role in the operation of the car. A faulty purifier leads to increased fuel consumption, reduced engine power and problems during technical inspection. If you had to replace the old detail, you can find out the scrap price for catalytic converter on ACM on the Autocatalyst website, where they offer to buy out used devices due to the precious metals they contain.
Most car owners contact the service only when the problem becomes obvious, although early detection of faults will save significant funds. Even without special diagnostic equipment, you can determine the condition of the gas neutralizer.
Visual inspection and simple heating test
The first thing every driver can do is conduct an external inspection. After the trip, turn off the engine and carefully inspect the body of the neutralizing element. There should be no visible damage, dents or signs of overheating. A change in the color of the metal indicates operation at extreme temperatures.
The heating test is carried out after a short trip. Let the engine run for 10-15 minutes, then turn it off and carefully run your hand near the exhaust system (without touching it). If the neutralizer emits strong heat, exceeding the temperature of the rest of the pipe elements, this may indicate clogging.
Checking by indirect signs
There are several indicators by which you can judge the condition of the neutralizing device:
- Fuel consumption – if you notice a sudden increase in gasoline consumption by 15-20% without changing your driving style, this may indicate problems with the neutralizer. This is especially indicative if the deterioration occurred suddenly, rather than gradually, and is not associated with seasonal factors or the quality of fuel at gas stations.
- A noticeable loss of engine power and acceleration dynamics indicates possible clogging of the neutralizer cells and an obstruction to the free passage of exhaust gases. The car becomes “sluggish”, accelerates worse, this is especially noticeable when driving uphill or overtaking. The appearance of a characteristic smell of “rotten eggs” (hydrogen sulfide) from the exhaust pipe indicates chemical degradation of the catalytic layer and the inability of the neutralizing element to fully clean emissions.
These signs can appear both individually and in combination. If at least two of them are detected, it is recommended to conduct a more thorough diagnosis.
Simple idle test
Another way to check does not require special skills. Start a cold engine and listen. If you hear a ringing rattling sound from the exhaust system, this may indicate the destruction of the internal structure of the neutralizer.
After warming up, the device should work almost silently. Any extraneous sounds, especially those that increase when you press the gas pedal, are a signal to check at the service.
This method is especially effective for detecting mechanical damage to the internal elements of the spare part. Constant shaking or knocking indicate serious problems.
Regular inspection and attention to the operation of the neutralizer will help to avoid expensive repairs. Remember that timely diagnostics and replacement of the neutralizer is the key to the proper operation of the car, fuel economy and safety.
