How important is the catalyst in a car?
The issue of the greenhouse effect and vehicle producing have been closely connected throughout history. Moreover, nowadays, the topic is an acute problem in the modern world. People try to protect the environment. Therefore, vehicle producers are trying to find ways to reduce emissions of harmful substances into it. A catalyst is one of the best options for this objective. By clicking on https://autocatalystmarket.com/us/en, you’ll find out a wide range of catalysts for your vehicle.
What is the Catalyst
The device is a part of the car’s exhaust system. It represents a metal can, inside of which there are ceramic soda coated with platinum. When exhaust gases go through it, most of the harmful substances burn out, reducing CO emissions. In simple terms, the catalyst is an environmentally friendly part of modern autos.
How does It Work
The catalyst is similar to the soot particle filter device. It comprises a porous metal or ceramic mass with small tubules that are covered with a layer of precious metal. Usually, platinum, palladium, or rhodium are used. They are added to the catalyst to ensure the performance of a catalytic process. The reaction takes place provided that the temperature reaches 300°С (573 K).
A car mechanic or producer should find the best place for installation. It is advisable to install the catalyst right after the engine at the very beginning of the vehicle’s exhaust system. At the same, place the catalyst at a sufficient distance from the engine so that hot gases do not cause overheating of the catalytic substances.
The catalyst starts performing its functions when the required temperature (300°С/573K) is reached. Therefore, it “eats” a small amount of fuel for its heating. Otherwise, its efficiency significantly decreases and will lead to the death of the part. It means its complete replacement. There is no way you can repair the car’s part.
The Device Helps Reduce Emissions
To put it simply, the product is a cleaner. The device protects the environment. It is an integral part of any modern car. The vehicle cannot pass the annual technical inspection without this part.
In modern vehicles, the catalyst converts harmful substances into three chemical compounds. First, it is heated to a temperature of about 300°C, then the oxidation of harmful gases begins. The device serves to neutralize nitrogen and hydrocarbon oxides harmful to humans and nature. When oxygen is added, these oxides are converted into harmless carbon dioxide (which is added to any carbonated drink), nitrogen (one of the main constituents of the air), and water.
How to Check Catalyst Condition
In order to check your catalyst condition, it is necessary to measure the pressure under three conditions:
- in front of the catalyst in standby mode;
- under a medium load;
- at full load.
Using a gas analyzer, car mechanicals identify the composition of the exhausted gases. Based on the results obtained, it becomes clear whether the chemical processes in the device are effective and whether the catalyst works properly. Remember that the catalyst must be checked every 50,000 km.
What Reduces the Operation Period of the Device
Let’s see what you should avoid to ensure a long-lasting operation period for your catalyst.
- The engine powering with inappropriate fuel. It is has too high or too low octane rating.
- A loosely mounted car muffler can lead to the destruction of acellular catalyst.
- Sudden cooling of the car’s exhaust system (for example, when moving through deep water).
- A clogged catalyst. If the vehicle’s part becomes clogged with refined products, this can lead to the following negative moments: engine power reduction; increased fuel consumption; warming up above normal operating temperature.
The device will become the best remedy for a car if it pollutes our nature too much. Take care of your vehicle and make timely repairs to ensure stable operation and pleasant rides.
