Is it possible to restore the catalytic converter after using low-quality fuel?

The problem of a clogged or damaged catalytic converter is familiar to many car owners. Frequent use of low-quality fuel leads to serious problems with the gas cleaning system. If the device is completely out of order and cannot be repaired, do not rush to throw it away – at the AvtoKatalist service you can find out recycled catalytic converter prices and profitably sell old equipment for recycling.

Signs of a clogged cleaning system

A clogged catalytic converter manifests itself with several characteristic symptoms. The first alarm bell is a loss of engine traction, especially noticeable when accelerating or climbing a hill. The engine begins to run unevenly, dips appear when pressing the gas pedal. If the clog is severe, the “Check Engine” indicator on the dashboard may light up.

Methods for restoring functionality:

  • Chemical cleaning of the system. Special flushing compounds added to the fuel tank help dissolve light contaminants inside the device. This method is effective only at the initial stage of clogging, when the deposits have not yet had time to harden. It is recommended to carry out the procedure every 15-20 thousand kilometers for prevention.
  • Pressure washing. Professional cleaning using special equipment allows you to remove even stubborn dirt. The method requires dismantling the device and can only be used in specialized services. The effectiveness of the procedure depends on the degree of damage to the internal coating.
  • Ultrasonic cleaning. A modern method of restoration, in which dirt is destroyed by ultrasonic waves. The method is considered the most gentle, since it does not damage the precious coating of the inner walls.

After any cleaning procedure, it is necessary to carry out computer diagnostics to check the efficiency of the system. Not all methods give a 100% guarantee of restoration.

When is repair impossible?

There are several situations in which restoring the device becomes impractical:

  • Mechanical damage to the case or internal structure makes it impossible for the cleaning system to function properly. Cracks, chips or deformations require a complete replacement of the device.
  • Complete destruction of the inner coating of precious metals deprives the device of its main function – neutralization of harmful substances. Such damage often occurs with prolonged use of low-quality fuel or engine overheating.
  • Melting of the ceramic filler due to engine operation on a rich mixture or misfires. In this case, a monolithic mass is formed that completely blocks the passage of gases.

In such situations, the only solution is to replace the device. Remember that the spent unit contains precious metals, so it can be handed over to specialized collection points.

Prevention is the best cure

To avoid costly repairs or replacement, follow simple operating rules. Refuel only at proven gas stations with high-quality fuel. Monitor the condition of the ignition system and promptly eliminate engine malfunctions. Regular diagnostics will help identify problems at an early stage, when they can still be eliminated without serious costs.
