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

In order to avoid violation of the guarantee certificates extending to components of systems of decrease in toxicity of the fulfilled gases you make check and service of the catalytic converter in the conditions of a workshop of car service.

General information

The catalytic converter is a component of systems of decrease in toxicity of the fulfilled gases, is switched on in structure of system of release and serves for decrease in issue in the atmosphere of toxic components. On the cars considered in the present manual catalytic converters of two types are used. The ordinary oxidizing converter allows to reduce the content in the fulfilled gases of hydrocarbons and monoxide of carbon. The three-functional catalytic converter in addition allows to reduce emission of nitrogen oxides (NOh).

Check

The diagnostic equipment for check of serviceability of a condition of the catalytic converter is expensive and extremely difficult in operation. At emergence of suspicions on failure of the converter, drive away the car for check on car repair shop.

 PERFORMANCE ORDER

1. Every time when the car climbs any reason above the ground, examine the converter on existence of signs of mechanical damages, traces of leaks and development of corrosion. Check a condition of welded seams and reliability of tightening of flange bolts of fastening of the device to sections of system of production of the fulfilled gases. The defective catalytic converter is subject to replacement.
2. Despite reliability of a design of the converter, there is rather high probability of its obstruction. The simplest way of check of passability of the converter is check with use of the vacuum gage:
   a) Connect the vacuum gage to the inlet pipeline;
   b) Having opened a butterfly valve, lift the frequency of rotation of the engine to 2000 rpm;
   c) Quickly dump gas;
   d) If passability of the converter is not broken, depression has to drop quickly no more than by 51 mm of mercury. concerning norm;
   e) If the measuring instrument does not register depression in 127 mm of mercury. either above, or quickly fluctuates around the highest value before returning to initial, therefore, passability of system of production of the fulfilled gases or the catalytic converter is broken.

Replacement
