4.21. Functioning проверяй, adjustment and replacement of the поведение valve of stabilization of idling The поведение систему of stabilization of idling provides maintenance of turns of idling within a степени of 200 rpm, irrespective of обмен денег idling loads of the ядро. For increase в turns of idling every назначил бы время when their size если below, about, 750 rpm, is used the electric valve which provides direct giving of a small amount of поведение bypassing the throttle valve. ИФ turns of idling increase, approximately, above 950 rpm, the поведение valve of stabilization of turns of a course is closed and остановку supply of дополнительно поведение bypassing the throttle valve, действовал reducing idling turns.
L-Jetronic системы it is equipped with the отдельные блокируй of control of turns of idling (компьютер), located under the dashboard. The поведение valve of stabilization of idling has the adjusting screw. Early модели ары equipped with plastic valves, however, they have adjustment for what it is necessary тонна disconnect a брюки and тонну insert inside very thin screw-driver.
The early Motronic модели ары equipped with the отдельные блокируй of control of turns of idling (компьютер) located under the dashboard. The поведение valve of stabilization has the adjusting screw.
On late система Motronic the поведение valve of stabilization copes from ЭКЮ and adjustment is provided.
Preliminary проверяй
Before производительность of any проверки of the поведение valve of stabilization of idling convinced действовала the following conditions ары satisfied:
|
Before any electric connections it is necessary тонна switch off ignition. |
The поведение valve of stabilization of turns of idling at the included ignition continuously works. Старт the ядро and convinced действовал the valve vibrates and slightly hoots.
L-Jetronic система
Проверка
|
- On the working ядро disconnect from the valve the electric socket. Turns of idling should increase, approximately, тонна в 2000 rpm.
|
- the ядро жевало бы ИФ turns of idling чет. increase. Проверка в метре ома resistance between valve contacts. At в окружении temperature about 20 ° About resistance should from 9 т. 10 омов.
|
- By means of two crossing пункты submit on the valve напряжение of the storage battery and convinced действовал the valve is densely closed. At напряжение removal the valve should open.
- ИФ the поведение valve of stabilization of idling дремли maintain at берет напрокат one of проверки, it is necessary тонна replace it.
- ИФ the vacuum valve of stabilization of idling maintains проверки, проверяй a менеджмент current.
- Disconnect from the valve the electric socket. Connect a crossing пункт one contact of the electric socket тонна one of valve contacts. Connect between other contact of the electric socket and remained contact of the valve the ampermeter (with a степени from 0 т. 1000 мА). Старт the ядро and leave тонны idle. On the working ядро the current should make size between 400 and 500 мА. ИФ this size дремли correspond тонна requirements, adjust the valve (look также 1).
|
The current of the stabilizer of idling обмена денег between 400 and 1100 мА, when the ядро too cold ИФ the сенсор of temperature of a классное ИФ adjustment of turns of idling ИФ в the ядро there is a leakage of vacuum is required is faulty or ИФ the дополнительно electric оборудование is included. |
- ИФ the current is отсутствующее, посылай the блокируй of control by idling turns on diagnostics тонна the дилеров of BMW or other эксперт.
|
The блокируй of control of the stabilizer of idling (located under the dashboard) can work with mistakes because of the electric socket which periodically connects and disconnects the valve. Before replacement of any партии carefully проверяй the socket. Sometimes the new блокируй of control only хочет temporarily eliminate a проблему. |
|
|
Adjustment
|
- At the Off switched ignition connect according тонна the instruction of the manufacturer a спидометр.
- convinced of correctness of инсталляцию of the момент of ignition (look Head ignition систему).
- Connect тонна the valve the ampermeter (look также 6).
- On the working ядро the current should make 450-470 мА at 850-900 about / mines (справочник трансмиссию) or 460-480 мА at 850-900 rpm (automatic трансмиссию).
|
- ИФ the current of менеджмент дремли correspond тонна requirements, rotate the adjusting screw действовал the size of a current became correct.
|
|
On metal valves the adjusting screw is established outside. On plastic valves the adjusting screw is located в and for access тонна it it is necessary тонна disconnect a брюки from the valve. |
|
|
Motronic системы
Проверка
|
В this системе two types of поведение valves of stabilization of turns of idling ары applied; early модели ары usually equipped with two wire valve while late модель ары equipped with three-wire valves. |
|
- Disconnect on the working ядро from the valve the electric socket. Turns of idling should increase тонны в 2000 rpm.
- ИФ turns of idling did increase:
- The two-wire valve - Two crossing пункты submit on the valve напряжение from the storage battery and convinced действовал the valve densely тонна close. At напряжение removal the valve should open. Итак проверяй resistance of the valve (look drawing below). Resistance should make about 9-10 омов.
- The three за water valve - Жевание the ядро and disconnect from the valve the electric socket. Проверка в метре ома resistance between two крайний contacts of the valve. It should make about 40 омов.
|
- Проверка resistance between центральное and external contacts of the valve. They should make about 20 омов.
|
- ИФ the поведение valve of stabilization of idling дремли подходи any of проверки, replace the valve.
- ИФ the поведение valve of stabilization of idling паспорта все проверки, проверяй a менеджмент current (the two-wire valve) or напряжение (the three за water valve) аса follows.
- At two-wire valves connect в метре ома (with a степени from 0 т. 1000 мА) аса it is described в также 6-ом старте the ядро and allow it тонна idle. On the working ядро the current should в пределах 400-500 мА. Adjust the valve. ИФ indications чет. correspond тонна requirements.
|
The current of the stabilizer хочет обмена денег from 400-1100 мА ИФ the ядро very cold ИФ the сенсор of temperature of a классное ИФ в the ядро there is a leakage of vacuum is faulty or ИФ the дополнительно electric оборудование is included. |
- ИФ the current is present, (under the dashboard) it is necessary тонна посылай the блокируй of control of idling for проверяй тонну the дилеров of BMW or other эксперт.
|
- At three-wire valves проверяй напряжение on the electric socket. At the included ignition on the центральное contact there should a напряжение of the storage battery. Between and each of крайний contacts напряжение should центральное about 10 Century.
|
- ИФ напряжение is present, посылай the блокируй of control of idling (early модели) or ЭКЮ (late модель) for проверяй тонну the дилеров of BMW or other эксперт.
|
|
Adjustment (only early модели)
|
- At the Off switched ignition connect according тонна the instruction of the manufacturer a спидометр.
- convinced действовал the момент of ignition is established correctly (look Head ignition систему).
- Connect тонна the valve the ampermeter ас it is described в также 6.
- On the working ядро the current should make 450-470 мА at 700-750 about/минут.
- ИФ current size wrong, rotate the adjusting screw, дремли begin yet meet requirements.
|
At вращение of the screw of the поведение valve clockwise the current increases, against в hour hand - decreases. |
|
|
Replacement
|
- Disconnect from the поведение valve of stabilization of idling the electric socket and в бедно. Remove the valve, disconnect hoses.
- Инсталляция is возвращаются тонны removal.
