Sudden death: why the catalytic converter in a car suddenly fails

The catalytic converter is not a particularly noticeable part in the daily use of a car. But as the end approaches, the driver immediately feels that the car completely refuses to leave.
The gradual failure of one or another system in the car is the best option for the car owner. He manages to prepare for the repair morally, financially and from a logistical point of view. And the catalyst sometimes ‘dies’ so quickly that you don’t even have time to blink. But this suddenness is obvious. Such incidents usually happen due to supervision or carelessness of the car owner.
The recent shortage of motor fuel in Russia is causing a booming trade in low-quality fuel and prompting unscrupulous dealers to sell replacement fluids under the guise of normal gasoline at a cheap price.
After pouring something like that into the tank, the motorist must be ready to pay. Not only can the engine itself have difficulty digesting such a ‘gift’. Poorly burning slurry in the cylinders will leave carbon deposits and soot, not just on the spark plugs and valves. All this waste will go straight into the catalyst and clog its honeycombs. By later filling the car with normal fuel, you can “burn out” most of the carbon deposits in the cylinder-piston group, but the catalyst cannot be saved in this way.
So don’t be surprised if the car suddenly starts stalling out of nowhere a few days after filling up with “scorched” fuel. This is a sign of catastrophic “constipation” in the catalyst.
By the way, ignoring problems with the ignition system by the driver can lead to a similar result. Many people turn a blind eye to the sometimes uneven operation of the engine and omissions in the operation of spark plugs or ignition coils. For example, I gave it a little gas and it went fine. Meanwhile, the unstable ignition of the fuel in the cylinders causes whatever is left unburned to end up in the catalytic converter. With the end result described above.
You also don’t have to worry about your engine guzzling oil. You can feel comfortable with the need to regularly add this fluid to the lubrication system. But remember: this is caused by it burning in large quantities in the cylinders. And the products of this process end up in the catalyst, inexorably and quickly polluting the honeycombs.
Suddenly, the pursuit of savings on gasoline costs can also “kill” him. Fuel prices have now risen sharply and many car owners are beginning to urgently switch their vehicles to natural gas. Of course, choose cheaper installers. Some of these “professionals” are not aware that the procedure often requires correct reprogramming of the electronic control unit. And neglecting it also leads to burning out the catalyst honeycomb. What quickly becomes clear to the car owner in the style of: “Oh, what happened?”
