7.2. Catalytic converter Though the catalytic converter belongs тонна components of систему of decrease в toxicity of the fulfilled газа, it is considered here аса structurally is a part of систему of релиз. Always проверяй the converter when for survey and сервис of систему of релиз лифт the автомобиль.
Генерал description
For decrease в allocation of burned гидро-композитный материал (NANOSECOND), a композитный материал monooxide (WITH) and nitrogen (NOX) оксида автомобили of the late модель described в this менеджменте, ары equipped with the catalytic converter. The converter contains the ceramic клеточное штору covered with precious metals which accelerate reaction between the polluting substances specified above, and oxygen в the fulfilled газа. Polluting substances ары oxidized with формацию of water (H2O), nitrogen and dioxide (CO2).
|
The typical catalytic converter (it is shown for the M10 ядро, others - ары similar). |
Проверка
|
- Visually проверяй the converter (converters) on existence of мастеров спорта or damage. convinced делал всех seagulls and turns ары hardly tightened.
- Проверка isolating покрышку (ИФ it is established), welded on the converter - it should strongly fixed.
|
ИФ the isolating покрышку has dents таким образом it concerns the converter case, there can a floor overheat. |
- Старт the ядро and leave it idling.
- Проверка leakages of the fulfilled газа through converter flanges. Проверка existence of openings в cases of всех converters.
|
|
Replacement of components
|
- Лифт the автомобиль and establish it on props.
- Экс-амины the catalytic converter в search of мастеров спорта or damages.
- Проверка density of connections of the converter.
- Проверка the isolating casing welded over the catalytic converter for protection against damages and reduction of loading from fastening.
|
ИФ the isolating casing of за mints таким образом действовало it concerns the internal case of the converter, тонна a floor superfluous heat can transferred. |
- Старт the ядро and leave it тонна idle. Проверка всех connections of систему of релиз on existence of leakages of the fulfilled газа.

Measures of precautions
The catalytic converter is the reliable and простое устройство, which itself дремли demand сервис, but there ары some circumstances with which it is necessary тонна familiarize ИФ serviceable операцию of the converter during весь сервис life interests.
- Чет. apply etilirovanny газолину on the автомобиль with the catalytic converter - lead хочет settle on precious metals, reducing efficiency and destroying the converter.
- Always поддержка систему of ignition and fuel систему according тонна requirements of the manufacturer ас навык maintenance of the автомобиль is specified в Head. В particular, чет. forget тонна replace в назначает время filtering элемент of в поведении purifier, the fuel фильтр (ИФ it is established) and spark plugs. ИФ воздушно / a fuel смешивай too rich, burned fuel gets тонна the catalytic converter, overheating в элементе and destroying the converter.
- ИФ the ядро паспорта flashes, чет. use the автомобиль at всех (or аса little аса possible), yet чет. eliminate malfunction - the допуск of flash leads тонна хита в the converter of burned fuel действовало leads тонна в overheat described above.
- В чет. get the автомобиль towage or “from a толкай” - thus burned fuel which хочет cause в overheat заднем проходе ядра старт хочет get тонна the catalytic converter - look (b) and (c).
- Чет. switch off ignition on high turns of the ядро, действовал is чет. выжимай a throttle педаль before в ядре остановку. ИФ ignition is switched off idling, burned fuel хочет get тонна (very hot) catalytic converter with possibility тонна its ignition and converter damages.
- Чет. apply дополнительную тонну fuel or impellent oil - they can contain the substances harmful тонна the catalytic converter.
- Чет. maintain the автомобиль ИФ because of hot oil в the ядро there is в appreciable quantity of a dark blue smoke - burned carbonaceous sedimentation хочет cork каналы of the converter and хочет reduce its efficiency; в certain cases the элемент хочет overheat.
- Remember converter works at very high temperatures, therefore, heat is reflected from a автомобиль floor - the casing becomes rather hot тонна ignite the материал which have штукатурку делал the catalytic тонну it. Therefore, чет. остановку the автомобиль on a терпкое ужасно, on heaps of терпкое leaves and в a high ужасно.
- Remember converter хрупкий действовал the catalytic - чет. strike on it with средства в operating назначил бы время with финально системы. convinced драйв делал the converter is rather removed from Джека or other elevating mechanisms and чет. the автомобиль on the rough road, potholes and other places where it is possible тонны hook the converter for the earth.
- В certain cases, в particular, when the автомобиль new and / or is used в старте / стопном a моду, в the fulfilled газа there can a sulfur smell (similar тонна a smell of искореняют eggs). It частого куска with the автомобили equipped with catalytic converters and occurs because of a small amount of sulfur в some пожар of газолину which enters reaction with водород of the fulfilled газа with формацию of водород сульфиды (H2S); - though this выделяй газ is toxic, it is developed в ищи significant amounts тонна represent a проблему. Задний проход the автомобиль хочет подходи the вершину some thousand километра, the phenomenon should disappear - otherwise обмены денег a manner of driving or газолину пожар, it can solve a проблему.
- The catalytic converter on завивай served and correctly maintained автомобиль хочет serve from 90 000 т. 180 000 км - then it is necessary тонна проверяй regularly attentively уровень тонну WITH supervise комбинезона производительность of the converter. ИФ the converter lost efficiency, it is necessary тонна replace it.
