A car has a neutralizer in the gas outlet organization, which often fails due to low-quality fuel. Let’s figure out what it is, what it is for and what to do in case of a blockage. The spare part is designed to clean harmful exhaust gases. It is located in the exhaust device, during its operation, chemical reactions occur: hazardous substances pass into safe forms, after which they are emitted along with the exhaust. Having passed this path, emissions become cleaner. And as a result, the car does less harm to the environment.
Drivers often face the question of what to do with worn-out components. After all, throwing them away is not always rational. On the platform https://autocatalystmarket.com/en/products/dodge you can sell your old filter and get money for it. The service connects car owners with buyers who are interested in buying such parts for recycling.
The device of this spare part
The basis of the part is ceramic or metal honeycombs. Depending on the model, a microlayer of palladium and rhodium or iridium is applied to the walls of the honeycomb. These metals have high chemical activity. When touching the coating, some of the gases enter into a chemical reaction with it. Some of the elements formed during fuel combustion are bound.
Modern devices are three-component:
- The first element binds nitrogen oxides.
- The second removes some of the unburned fuel elements. Most of the carbon monoxide is removed.
- The third element is a sensor. It analyzes the emissions at the outlet, the data is transmitted to the on-board computer.
Manufacturers write that the service life of such a filter is 100-150 thousand kilometers. But in practice, problems can arise even with a lower mileage, especially in large cities, where you often have to stand in traffic jams. Depending on the operating characteristics, replacement can be done every 3-7 years.
Why does the breakdown occur
The main cause of the malfunction is the burnout of the metal layer covering the honeycomb. This is a natural process, as a result of which the quality of the exhaust deteriorates. The on-board computer shows a burning “check”, and in some cases does not allow the engine to run at all, turning off the ignition.
Low-quality fuel also accelerates the burnout process. Often, the octane number of gasoline is increased by adding lead, this increases the load on the filter, reducing the service life. In the case of diesel fuel, the owner himself can accelerate the failure by using “anti-gel” additives in winter.
In some cases, a faulty engine can be the cause of the breakdown. If the ignition is set incorrectly and there are problems in the organization of the power supply (the latter is especially important for diesel engines), the burnout of the catalytic layer accelerates.
Features of removing the component
Below, we will consider what nuances of removing the part should be taken into account. First of all, you need to decide how to bypass the lambda probe. After removing the neutralizer, the sensor will constantly give an error. To bypass the sensor, they usually cheat.
This is a spacer that moves the sensor away from the exhaust emissions, as a result, it records more oxygen. The dummy is screwed in place of the sensor, and the device is installed in it. This solution works stably, although it has its drawbacks. Any interference with the design of the car leads to its removal from the warranty. Think about what will happen if an engine malfunction occurs, which falls under the warranty case.
