Gasoline engines
- A) DO NOT use leaded gasoline or LRP fuel on vehicles equipped with a catalytic converter. Lead will build up on the noble metal catalytic coating, reducing the efficiency of the neutralization and eventually destroying the catalyst.
- b) Always properly maintain the ignition and fuel system according to the maintenance schedule.
- V) If the engine misfires, do not drive the vehicle (or. at least keep its use to a minimum as possible) until the problem is corrected.
- G) DO NOT start the vehicle by pushing or towing as this may introduce unburned fuel into the catalytic converter, causing the converter to overheat after starting the engine.
- d) DO NOT turn off the ignition when the engine speed is high.
- e) DO NOT use fuel or engine oil additives as they may contain substances that are harmful to the catalytic converter.
- and) DO NOT operate the vehicle if the engine is burning oil, which is accompanied by a noticeable plume of blue smoke.
- h) Remember that the catalytic converter operates at very high temperatures. Therefore, after a long drive, DO NOT park the vehicle on dry brushwood, tall grass, or over dry leaves.
- And) Remember that the catalytic converter is a FRAGILE assembly. When servicing, do not tap on it with tools.
- To) In some cases, the exhaust smells of hydrogen sulfide (smells like rotten eggs). This is a common symptom for many vehicles equipped with a catalytic converter. The problem should disappear after the car has traveled several thousand kilometers.
- l) The resource of a catalytic converter used on a regularly serviced and properly operated car should be 80,000-160,000 kilometers. A neutralizer that has lost its effectiveness must be replaced.
