Modern foreign cars are equipped with an expensive cleaning system, which is better known as a catalyst. The cylindrical device serves to minimize the harmful components that are formed after the combustion of the fuel. Some car owners are sympathetic to expensive equipment, because if all consumers get rid of the original catalysts, then our air will become dangerous for the lungs.
Design features of the catalyst.
The device is made in a cylindrical shape and contains a ceramic core. If you look at the filter in a slice, you will see multiple "honeycombs". Honeycomb fibers are processed with valuable alloys, which provide cleaning.
Nitric oxide and CO molecules are extracted from the exhaust gases through chemical reactions. As a result, safer compounds enriched with oxygen come out.
The catalyst works under the guidance of special sensors. These devices are installed between the muffler and the engine, and when the throughput of the exhaust system changes, they send a corresponding message to the control panel.
On average, the catalyst regularly serves for 200 thousand kilometers. However, due to negative circumstances, such as low quality gasoline, vibration, leakage of working fluids or mechanical damage, the service life of the device is reduced.
The principle of the converter.
The catalyst is placed closer to the outlet pipe. Close proximity to the engine is not accidental. To accelerate chemical reactions, a high temperature is needed within 300 degrees, which ensures the location near the fuel combustion center.
The device consists of a metal case, a mounting block and a filter part. The latter can be made of ceramic or metal. Ceramic options are less resistant to damage, however, it is these models that are equipped with imported foreign cars of European and Japanese production. The thing is that the main component of the filter is valuable metals, and not the structure of honeycombs. Therefore, the material of the filter fibers is the part where you can save on production.
The filtering part, containing valuable metals such as palladium, platinum, chromium, neutralizes the chemical caustic CO and nitric oxide, which are formed as a result of fuel combustion. Residues of gasoline that did not burn out in the engine, when in contact with honeycombs, instantly oxidize “burn out” and release oxygen.
How to determine the clogging of the catalyst?
In the normal state, the operation of the catalyst is not accompanied by any negative manifestations. However, when the filter starts to clog, sooner or later unpleasant factors begin to appear:
- An error message in the exhaust system is displayed on the control panel. If the error does not disappear after restarting the computer, it means that the catalytic converter is broken.
- Exhaust fumes are darker in color and have a pungent odor.
- When accelerating, the engine begins to "choke" and loses its original power.
- Fuel consumption increases. As a result of the reduction in the capacity of the exhaust system, the engine "burns" less fuel and passes more particles into the exhaust system.
Like any filter, the catalyst will fail sooner or later. Practice shows that it makes no sense to wait until the filter is completely destroyed, and it is better to clean or replace at the first symptoms. It should be noted that cleaning allows only for a short time to extend the "life" of the catalyst, after which a complete replacement will be required.
Due to the fact that the catalyst contains a number of valuable alloys, its value remains even in non-working condition. You can hand over a worn device to a specialized company https://katalizatory.kiev.ua. Acceptance of catalystsis performed after the spectral analysis procedure.
