The control of structure of the fulfilled gases
Check
The Katalitichesky converter
The diagnostic equipment for check of serviceability of a condition каталитического the converter is expensive and the extremely difficult in operation. At occurrence of suspicions on converter refusal, drive away the car for check on a car repair shop.
Each time when the car for any reason rises over the earth, examine the converter on presence of signs of mechanical damages, traces of leaks and corrosion development. Check a condition of welded seams and reliability of a tightening фланцевых bolts of fastening of the device to sections of system of release of the fulfilled gases. Defective каталитический the converter is subject to replacement.
Despite reliability of a design of the converter, there is high enough probability of its corking. The elementary way of check of passableness of the converter is check with vacuum gauge application.
|
|
- Connect the vacuum gauge to a source of depression of the inlet pipeline (Procedures of repair of diesel engines of 1.7 l and 2.0 l without their extraction from the car see).
- Warm up the engine to normal working temperature, translate the selector lever in position Р (models with АТ), or include neutral transfer (models with manual transmission) and cock a lay brake.
- Consider vacuum gauge indications at single turns of the engine.
- Quickly open throttle заслонку almost against the stop, then at once release, having dumped turns to the single. Consider and write down vacuum gauge indications.
- Repeat the described check still three times, each time writing down result.
- If the result of the fourth measurement appears more than on 2.54 mm hg below the instrument read at single turns, hence, there is a probability of infringement of passableness of the converter, or the muffler.

Ljambda-probe (the oxygen gauge)
|
|
- Find an electric socket of the gauge. From a socket underside enter the unbent writing paper clip into a nest of contact of an alarm wire (the plug № 1 [+]), the second paper clip enter into a plug nest № 2 (weight). Connect to the first paper clip positive щуп the voltmeter, negative connect to a paper clip entered into the grounding plug. Cock a lay brake, translate selector AT lever in position Р, on models with manual transmission choose neutral transfer. Поддомкратьте redock of the car also establish it on props.
|
|
- Start the engine and start to trace changes of alarm pressure of a ljambda-probe.
|
|
Try not to touch to разогретым with surfaces of system of release of the fulfilled gases! |
- At the initial stage the cold gauge should develop a constant signal amplitude 0.1—0.2 In (a mode of the opened contour). After nearby two minutes the engine will reach normal working temperature and the gauge indication will start to fluctuate in limits from 0.1 to 0.9 In (a mode of the closed contour). If the system does not pass in a mode of the closed contour, or passes with is inadmissible the big delay (the lazy gauge), replace the gauge.
- Check up also serviceability of functioning of a heater of a ljambda-probe. Disunite a socket of electroconducting of a probe and connect an ohmmeter between heater plugs (plugs №№ 3 and 4). Nominal resistance makes 10—40 Ohm.
- Check up serviceability of giving of a food on a heater. Disunite an electric socket and measure pressure on it from outside a plait between the plug № 4 and weight. At the included ignition (do not start the engine) the voltmeter should fix pressure of the battery. If a food is absent, check up an electroconducting condition on a chain site between the main relay, ECM and a ljambda-probe.
- At negative results listed above checks, replace the faulty gauge.

- Do not fill equipped каталитическим with the car converter неэтилированным fuel, - lead containing in it is postponed on the surfaces of the catalyst covered with rare-earth metals that in an essential measure reduces efficiency of functioning of the converter and finally can lead to its full exit out of operation;
- Watch serviceability of a condition of components of system of release of the fulfilled gases, regularly make necessary checks according to the Schedule of routine maintenance of the car (Routine maintenance see the Head);
- At occurrence of admissions of ignition, it is necessary to refuse using a vehicle till the moment of elimination of malfunction, - not burnt down fuel getting to the converter can then ignite and be at the bottom of a catalyst exit out of operation;
- For the same reason it is necessary to refuse start of the engine by towage or car pushing;
- Do not switch off ignition at high turns of the engine;
- Do not use any additives to fuel and impellent oil, - they can contain, harmful for каталитического the converter components.
- At occurrence on an exit of system of release of the fulfilled gases of the grey loop which is a consequence of burning out of impellent oil composers of the present Management also recommend to refuse car operation (the point see);
- Remember that каталитический the converter functions at very high working temperatures, - do not park the car on covered to a dry grass or last year's foliage platforms;
- Remember that каталитический the converter can be easily damaged at blows, - be careful, performing any works near to it;
- Occurrence of a smell of hydrogen sulphide (rotten eggs) in the first days of operation of the new car is a consequence of normal functioning каталитического the converter, - the smell should disappear after first several thousand kilometres of run;
- At the serviceable car service life каталитического the converter makes to 150 000 km. In case of decrease in efficiency of functioning каталитический the converter is subject to replacement.
The description of procedures of removal and installation каталитического the converter – see Removal and installation of a final collector.
