6.6. Catching система паров газолину (EVAP) Генерал description
The система EVAP scheme on the M10 ядро (the others - similarly)
|
|
This система is usually established on the автомобили equipped with the catalytic converter. |
When the ядро is muffled, fuel в a fuel заправляйся evaporates, created pressure паров. The catching систему паров газолину accumulates тезис pairs в capacity with в адсорбере. Under way the removal valve паров is a little slightly opened and fuel pairs gradually arrive в the inlet трубопровод and burn. When старт of the cold ядро or the ядро is личинку idles, the removal valve паров дремли allow pairs тонна arrive в the inlet трубопровод and тонну enrich a fuel смешивай excessively.
Removal valves паров two types ары applied: with electric менеджмент and vacuum менеджмент. Тонна define, what valve is established on your автомобиль, track a брюки from capacity with в адсорбере, yet хочет находи the valve. Some valves ары established on the inlet трубопровод, others - near capacity with в адсорбере. Look, whether there is on the valve в electric socket or the vacuum Лину approaches тонну it.
The faulty систему EVAP influences road производительность of the ядро only when it is heated-up. The система EVAP usually is at the bottom of difficult cold старт or other проблемы on the cold ядро.
Проверка
Removal valve паров vacuum-operated
|
|
- Disconnect from the valve the vacuum Лину and blow в the bigger союза of the valve. The valve should подходи closed and поведение should.
|
|
On some модель the thermovacuum valve is established, which interferes with removal паров, while the temperature of a хочет более классно reach, about, 46 ° S.Proverte this valve тонны convinced of its операцию under the influence of a razryazheniye at the correct temperature. The valve is usually located в the inlet трубопровод near the temperature switch and the сенсор of temperature of a более классно. |
- Disconnect from the removal valve паров a thin vacuum брюки and the справочник vacuum откачивай on в entrance of the valve create a razryazheniye. The valve should open and старт тонна подходи поведению.
- ИФ the тест yields отрицательный result, replace the valve.

|
The removal valve паров with electric менеджмент
|
|
- Disconnect from the valve всей Лины (except the electric socket) and move it тонна a place convenient for testing.
|
|
- Проверка действовала the valve at inclusion of ignition publishes click.
|
|
|
- ИФ the valve дремли publish click, disconnect from the valve the socket and a control lamp or the вольтметры проверяй силу supply.
|
- ИФ напряжение of the battery is present, but the valve дремли work, replace it. ИФ напряжение is отсутствующее, проверяй the блокируй of control of Motronic and a wire.
|
|
Capacity with в адсорбере
|
|
- Отметка в размещении of всех hoses, then disconnect them from capacity.
|
|
- Put нападающий capacity from a фиксацию collar. On some модель it is necessary тонна weaken a collar.
|
- Visually проверяй on capacity existence of leaks and damages.
- At detection of leaks and damages replace capacity.
