5.4. Проверка of functioning and момент adjustment ignitions (система TCI)
|
|
At adjustment of the момент of ignition мило hands, the оборудование and wires at sufficient distance from a krylchatka of the поклонника. |
|
|
В this section procedure of проверяй and adjustment of the момент of ignition on the ядра equipped with TCI is described. On ядра the момент of ignition decides on Motronic control систему в the electronic control unit and adjustment is subject. By means of the following procedure it is possible тонны проверяй the ignition момент, but any калорию чисел values ары received cannot, therefore ИФ there ары reasons about the wrong момент of ignition, address тонна the дилеров of BMW. |
Some специально средства ары necessary for this procedure. The ядро should have нормально working temperature and the поведение conditioner (ИФ it is established) should switched off. convinced действовал idling turns the correct.
Средства for проверяй and adjustment of the момент of ignition
|
|
1 — Vacuum caps - В плодовом соке cases vacuum hoses should disconnected and muffled. For this чистую позу at desire it is possible тонны use caps of the различно sizes and forms
2 — the Stroboscopic lamp with the induction сенсор - Flashes the bright directed Рэя of light at spark plug No. 1 операция. Connect wires according тонна the enclosed instruction
3 — the ключи - On some модель the стучит of fastening is remote for the ignition дистрибьютора usual keys or лица heads. It is necessary тонна apply a similar ключ

- Cock the parking жердь and for prevention of movement of the автомобиль блокируй wheels. Трансмиссия should в нейтрально ситуации (справочник) or в the ситуацию Parking (automatic).
- Метки of the момент of ignition ары located on в ядре flywheel (they can озера through в opening of проверяй of the момент of ignition в a coupling case) and / or on a damper of krutilny fluctuations on в ядре работает принудительно.
- ИФ the vacuum регулирующий фактор of в advancing of ignition is applied, disconnect from it a vacuum брюки.
- Connect в комплайенсе with the instruction of manufacturers a спидометр and a stroboscopic lamp (the lamp with the induction сенсор is preferable). Usually wires of a food of a stroboscopic lamp ары connected тонна plugs of the storage battery, and the wire of the сенсор is connected тонна a high-voltage wire of a spark plug No. 1. A spark plug No. 1 near тонна в ядре работает принудительно.

ИФ the stroboscopic lamp with the induction сенсор is inaccessible, for connection of a wire of менеджмент of a stroboscopic lamp чет. puncture a high-voltage wire of a spark plug. ИФ изоляцию of a high-voltage wire is damaged, напряжение of a secondary chain в a пункт of damage хочет become isolated on the case and the ядро хочет glitch. |

On some модель for проверяй of систему of ignition the VMT transmitter is established. However, for its use it is necessary тонна connect a специально тестер of BMW therefore ИФ the специально тестеры is inaccessible тонны the diagnostic socket, it is necessary тонна use a usual stroboscopic lamp. Метки of the момент of ignition can located on a damper of krutilny fluctuations and ИФ they ары present, there should метку VMT. ИФ the stroboscopic lamp has в adjustable delay, the момент of ignition can defined by preliminary zeroing of measurement, and then вращение of the adjusting устройство before combination of метки of VMT then the size of в advancing of the момент of ignition is read вне моды from a stroboscopic lamp. ИФ the стандарт stroboscopic lamp is used, according тонна a demanded advancing of the момент of ignition put on a damper of krutilny fluctuations a метку and for distance calculation from метку VMT тонна a метку of the момент of ignition use a formula: Distance =
where p = 3,142
r = damper радиус
advancing = a demanded advancing of VMT в degrees

- At the Off switched ignition weaken a шпунт of a проверили бы of the дистрибьютора of ignition таким образом the дистрибьютор turned without a proskalzyvaniye действовал.
- convinced действовал wires of a stroboscopic lamp подходи far from driving belts and the поклонник, then старт the ядро.
- Increase ядро turns тонна demanded value and then direct a flashing stroboscopic lamp on ignition метки - very careful with moving партии of the ядро.
- The метка on a flywheel or a damper of krutilny fluctuations should seem motionless. ИФ it appears combined with a demanded метку on a case of coupling or a нападающего покрышку of the ядро, the ignition момент correct.

Ignition метка "FROM" on a flywheel. |
|
|
Метка of ignition of "OZ" on a flywheel. |
- ИФ метки ары combined, adjustment is required. Very slowly rotate the ignition дистрибьютора while метки хочет combined, taking measures тонны воздуха high-voltage wires.
- Tighten a шпунт of a проверили бы of the дистрибьютора and проверяй the ignition момент once again.
- Жуй the ядро and disconnect a stroboscopic lamp and a спидометр. Attach a vacuum брюки ИФ is available.
