The catalytic converter - the general information and precautionary measures

The catalytic converter is rather simple on a design, is reliable and does not need special leaving. However, for the purpose of converter maintenance in working condition, it is necessary to observe some special service regulations of the car (see below).

Petrol engines

   a) At all do not use for filling of the car equipped with the catalytic converter etilirovanny gasoline - the surface of an active layer of the converter soon will appear is tightened by a lead film that in considerable to a measure will lower efficiency of functioning of the device;
   b) Strictly observe the schedule of service of power supply systems and car ignition;
   c) Stop car operation at emergence of admissions of ignition until the cause of defect will be eliminated;
   d) Do not make engine start by pushing or car towage. Not burned down fuel from combustion chambers, getting on a surface of an active layer of the converter, will cause an overheat of the last after engine start;
   e) Do not switch off ignition at high turns of the engine;
   f) Do not use any additives to fuel or impellent oil;
   g) Stop car operation at emergence on an exhaust of the dark blue smoke testifying to hit of oil in chambers of combustion;
   h) Do not forget that the working temperature of the catalytic converter can reach very high values. Do not park the car on covered with easily flammable materials (a dry grass, leaves) platforms;
   i) Remember that the catalytic converter is the fragile device. Do not drop it and do not shake at works on service of system of production of the fulfilled gases;
   j) In certain cases at operation of the engine of the new car equipped with the catalytic converter there can be a hydrogen sulfide smell. It should not cause concern, - through some thousand kilometers of run the smell will disappear by itself;
   k) Service life of the catalytic converter under condition of a conscientious attitude to care of the car makes from 50 000 to 100 000 km of run. If after that efficiency of its functioning falls, it is necessary to replace the device.
