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

 PERFORMANCE ORDER

1. 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.
2. 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.
3. 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 a source of depression of the inlet pipeline (see the Head Dvigatel);
b) Warm up the engine up to the normal working temperature, transfer the selector lever to situation "P" (models from AT), or include neutral transfer (models with RKPP) and cock the parking brake;
c) Consider indications of the vacuum gage at single turns of the engine;
d) Quickly open a butterfly valve almost against the stop, then at once release, having dumped turns to single. Consider and write down indications of the vacuum gage;
e) Repeat the described check still three times, every time writing down result;
f) If the result of the fourth measurement appears more than on 2:54 mm of mercury. below the instrument read at single turns, therefore, there is a probability of violation of passability of the converter, or muffler.

Replacement of components

 PERFORMANCE ORDER

1. Before an otdavaniye the carving of flange fixture of the catalytic converter should be impregnated with the getting structure.

2. Give fixing nuts and take the catalytic converter from under the car.
3. Installation is made upside-down.
