The catalytic converter – the general information, check of a state and substitution

To avoid the violation of the certificates of guarantee that stretch out it component of systems of the reduction in the toxicity of the carried out gases it carries out the control and the service of the catalytic converter in the conditions of a workshop of the service of the car.

General information

The catalytic converter is a component one of systems of the reduction in the toxicity of the carried out gases, it is lit in the structure of the system of launch and services of the reduction in the question in the atmosphere of component poisons. In the cars considered in the present manual catalytic converters of two types they are in use. The ordinary oxidation convertedor allows to reduce the content in the carried out gases of the hydrocarbon and carbon monoxide. The catalytic converter functional three besides that allows to reduce the emission of oxide of nitrogen (NOh).

To check

The diagnostic equipment of the check of the usefulness of a condition of the catalytic converter is expensive and extremely difficult in the operation. In the moment of the emergence of suspicions in the failure of the convertedor, there removes the car for verificam the workshop of repairs of the car.

ORDER OF REALIZATION

1. Every time when the car raises any reason above the land, it examines the convertedor in the existence of signs of mechanical damages, aspects of holes and development of the corrosion. There check a condition of welded sewings and the confidence of the pressure of pins of flange of the fixation of the device the sections of the system of the production of the carried out gases. The incorrect catalytic converter is subject to the substitution.
2. In spite of the confidence of a drawing of the convertedor, there is quite high probability of his obstruction. The most simple way of the check of passability of the convertedor is that they tally with the use of the measure of vacuum:
   a) The vacuum measure adheres to the entry oil pipeline;
   b) Having opened a valve of butterfly, lift the frequency of the rotation of the motor to 2.000 revolutions per minute;
   c) Quickly heap gas;
   d) If passability of the convertedor one does not break, the depression will fall quickly not more than in 51 mm of mercury. about standard;
   e) If the instrument of measuring does not register the depression in 127 mm of mercury. in top, or quickly float around the highest value before returning to the initial, therefore, passability of the system of the production of the carried out gases or the catalytic converter is broken.

Substitution
