Protecting our environment is always necessary, and it doesn’t matter if you are walking or driving. In order to ensure a clean and compliant exhaust, there is a specific part in the machine. The catalyst is the very component of the system that burns the mixture of gases and ultimately releases clean vapors.
What is he like? Firstly, a ceramic honeycomb is installed in it. With its help, the area on which the exhaust contacts the surface coated with a platinum-iridium alloy increases. Next, contact with the catalytic layer occurs, the remaining gases are found with oxygen and burn out, resulting in the necessary concentration.
It is worth noting that in the Russian environment, the fuel catalyst is practically tortured, since gasoline produced in our country contains a considerable proportion of tetraethyl lead, which very quickly leads to deterioration in the operation of these devices.
The catalyst is a certain obstacle for clear engine actions. But do not take this with hostility. When this part is clean and not clogged with anything, the machine will work like a clock, but if there is any pollution, then you need to check the mechanism. The fact is that the catalyst is located in the muffler, and when it malfunctions, it turns out as if a rag was inserted into the pipe. Therefore, it turns out that the engine simply can not cope with the exhaust volume, which has nowhere to go.
Modern latest catalysts cost a lot of money, but what if replacement is needed? On many cars of this type of spare parts there can be up to 4 pieces. In this case, either a flame arrester or a universal catalyst can become a
lifebuoy .
What is the difference between these devices? A catalyst is a part that performs several functions. Firstly, it is engaged in the afterburning of the mixture, and secondly, it breaks the gas flows. The flame arrester is only responsible for the second ability, but its installation in Russia is allowed. When choosing such a catalyst substitute, it is worth considering the size of the engine. On a machine with an engine of less than 2 liters, simple flame arresters are installed, but above this mark you will need individual parts. They are created on the basis of the catalyst itself and have noise isolation, which allows the car to move in a normal rhythm.
Many drivers complain about the knocking of a car while driving, which begins to be heard from under the seat, but do not understand its root causes. Everything is pretty simple. When cells that are made of ceramic material begin to burn through in the catalyst, their material breaks down over time and crumbles onto the walls of the housing, as a result of which, when moving, the pieces begin to actively knock on the walls of the part.
Some motorists are trying to replay the silencer, that is, they simply cut the catalyst out of the system and install a pipe in its place. This procedure does not make any sense, as this will lead to early wear of the resonator. Therefore, make the right conclusions, because the catalyst is a necessary part of your car.
