catalytic converter

The catalytic converter is a simple and reliable device that does not require maintenance. However, the owner of a Transporter T4 equipped with a catalytic converter should follow some guidelines to ensure its smooth operation.
a) Leaded gasoline must not be poured into a vehicle equipped with a catalytic converter.
Lead from gasoline settles on the active inner surface of the converter, reducing its efficiency and, as a result, destroying the converter. b) Monitor the condition of the power supply and ignition systems of the car.
Service these systems at the recommended intervals. Change the air filter element, fuel filter (if equipped) and spark plugs in a timely manner. If the air-fuel mixture entering the engine combustion chambers is excessively enriched, then part of the mixture will enter the converter and burn out already in it, leading to its overheating and failure. c) If a misfire occurs, do not continue driving until the problem is completely fixed.
Misfire leads to incomplete combustion of fuel in the engine and subsequent catalytic converter failure. d) It is not recommended, for the same reasons, to start the engine from a tow.
e) It is forbidden to turn off the ignition at a high crankshaft speed, because.
in any mode other than idling, incomplete combustion of the fuel occurs. f) Do not use fuel or oil additives as they may contain chemicals unacceptable for the catalytic converter.
g) Do not continue to operate the vehicle with increased oil consumption or the appearance of distinct blue (gray) smoke from the exhaust pipe.
Hydrocarbons passing through the converter can block its channels, which will lead to a decrease in the efficiency of gas cleaning and possible overheating of the converter. h) Remember that the converter only works at high temperatures and therefore gets very hot.
Do not park your vehicle on a lawn with dry grass or leaves. i) The catalytic converter must be protected from impact.
Avoid shock during repair work. Be extremely careful when servicing the exhaust system, do not allow the heels of the jack or support to rest against the converter housing. Avoid driving on bad or country roads and off-road to avoid mechanical damage to the pipes of the exhaust system and catalytic converter. j) With a short service life, an unpleasant sulfurous odor (the smell of rotten eggs) may appear from the exhaust pipe of the car.
This feature is found in many vehicles equipped with a catalytic converter. This gas is toxic, but its content in the exhaust is small and therefore it does not pollute the environment and does not affect human health. After several thousand kilometers of the car, the smell disappears. Changing your driving style or using a different brand of gasoline can also solve the problem. k) The catalytic converter, when used correctly, does not lose its effectiveness for 100-150 thousand kilometers. Further, it is necessary to measure the level of CO in the exhaust at the recommended time to check the functioning of the converter. If the catalytic converter no longer provides effective exhaust gas cleaning, it should be replaced.
