A neutralizer is a complex device containing precious metals that participate in chemical reactions of cleaning emissions. Many car owners mistakenly believe that this device creates additional resistance and increases fuel consumption. Let’s figure out if this is really true.
A serviceable neutralizer has virtually no effect on fuel consumption. The electronic engine control unit accurately calculates the required amount of fuel for optimal operation of the entire system. At the same time, the cleaning process itself occurs due to chemical reactions that do not require additional engine energy.
If you are planning to replace an old neutralizer, do not rush to throw it away. Study the scrap catalytic converters price list on the Avtokatalist service, where you can profitably sell a used device due to the content of precious metals in it.
The economic component of the issue
Many owners of used cars are faced with a dilemma: to repair or remove a faulty catalytic converter. Removal may seem like a more profitable solution, but this is a deceptive savings. A car without this device will not pass a technical inspection, and fines for its absence can significantly exceed the cost of repairs.
When does consumption really increase?
- Contamination of channels. When internal channels are clogged with combustion products of low-quality fuel, gas permeability deteriorates. The engine begins to work with an increased load, which increases fuel consumption by 10-15%. The drop in power is especially noticeable during acceleration and driving uphill.
- Problems with sensors. A malfunction of the oxygen sensor leads to incorrect operation of the control system. The on-board computer supplies an enriched fuel mixture, significantly increasing consumption – up to 20-30% of the norm.
- Mechanical damage. Cracks or deformations of the housing create additional resistance to the flow of gases, forcing the engine to work at increased speeds.
Each of these problems requires immediate service. Delaying repairs can lead to complete failure of the device and the need to replace it.
Prevention and maintenance:
- Fuel mode. Use only high-quality fuel from trusted gas stations. Cheap gasoline often contains increased amounts of sulfur and impurities that quickly contaminate the internal surface of the device. The correct choice of fuel can extend the service life by 2-3 years.
- Maintenance. Carry out timely diagnostics and maintenance of the ignition system. Misfires lead to unburned fuel getting inside the device, causing overheating and destruction of the internal structure.
- Driving style. Avoid sudden acceleration and braking. Aggressive driving increases the load on all vehicle systems, including the emission cleaning system.
Compliance with these rules will help significantly extend the service life of the entire cleaning system. Regular diagnostics will allow you to identify faults at an early stage and avoid costly repairs.
So, a serviceable neutralizer does not increase fuel consumption. Increased fuel consumption indicates a malfunction of either the device itself or the engine systems associated with it. Timely diagnostics and high-quality maintenance will help avoid unnecessary expenses on fuel and repairs. If replacement is necessary, do not forget that the old device can be sold profitably through specialized services.
