The exhaust gas neutralizer can begin to lose its effectiveness gradually, making the problem imperceptible to the driver in the initial stages. The first signal is often a slight loss of power during acceleration, especially noticeable at high engine speeds. The internal elements of the converter slowly deteriorate, creating an obstacle to the passage of gasses. If such symptoms are detected, it is worth thinking about the diagnosis of the purification system, and if the problem is confirmed – do not rush to throw away the old converter, because it can be sold profitably through the service Autocatalyst.
Progression of the problem
Over time, the situation usually worsens, leading to more serious consequences for the engine. Many car owners, when faced with the need for replacement, research cadillac converter scrap prices to estimate the possible compensation of repair costs. A clogged converter creates over-pressurization in the system, which leads to engine overheating and increased fuel consumption. Ignoring these symptoms can lead to complete destruction of the converter’s internal structure and particles entering the engine.
The main signs of critical malfunction
With severe clogging of the cleaning element, the following symptoms are manifested:
- The engine begins to work unsteadily at idle speeds, periodically stalls for no apparent reason.
- When pressing the gas pedal, the car has difficulty gaining speed, as if it is struggling with an invisible obstacle.
- Fuel consumption increases by 15-30 percent due to a violation of the combustion process of the working mixture.
- A characteristic smell of hydrogen sulfide appears, especially noticeable after a long parking of the car.
- The engine begins to overheat even when driving in a quiet mode on the highway
- The electronic engine management system generates errors related to the composition of the fuel mixture.
- When driving, a metallic ringing sound is heard, which increases with increasing revolutions.
Ignoring these signs can lead to irreversible consequences for the engine. The cost of repair in such a case will many times exceed the cost of timely replacement of the converter.
Effect on engine components
A defective neutralizer creates increased resistance to the flow of gasses, which leads to disruption of the entire powertrain. Engine temperature rises, oil loses its properties faster than usual, valves and piston rings work under increased load. Oxygen sensors transmit incorrect data to the electronic control unit, which, in turn, incorrectly regulates the composition of the fuel mixture.
Consequences of prolonged use
Continued use of the car with a clogged cleaning element inevitably leads to serious problems. Elevated exhaust gas temperatures can lead to piston and valve burnout. Destroyed particles of ceramic filler can get inside the cylinders, causing scoring on their walls. The cost of an engine overhaul will be several times the price of a new converter.
Prevention and avoidance
To prevent clogging of the neutralizer, it is necessary to perform regular maintenance of the car. Particular attention should be paid to the quality of the fuel and engine oil used. Timely diagnosis and troubleshooting of the ignition system and fuel equipment will help to significantly extend the service life of the cleaning system.
