3.3.6.3. Check and installation of the moment of ignition (only for system TCI)

THE GENERAL DATA

Check is carried out on the heated-up engine. Be convinced that idling turns correspond to norm.

Labels for ignition installation are put on a flywheel (are visible through an aperture in колоколообразном картере a check point) and / or on a pulley-uspokoitele on a sock коленвала.

The prevention

In system Motronic ignition check is supposed only. However in the absence of the exact data for the given system in case of abnormal work of ignition it is necessary to address in car-care centre.

Aperture in колоколообразном картере a check point for illumination by a stroboscope at ignition installation

PERFORMANCE ORDER

1. Disconnect a hose of a vacuum regulator. 2. Connect a tachometre and a stroboscope, being guided by the instruction of the manufacturer of devices. It is recommended to apply a stroboscope with the induction gauge. As a rule, conclusions of a food of a stroboscope join battery poles, and a gauge conclusion – to a wire of a candle of 1st cylinder. The prevention On a part of cars for check and installation of the moment of ignition gauge VMT (the label of the moment of ignition in these cars as a rule is absent) for which the special tester which joins in a diagnostic socket is intended is provided. The tester is used in car-care centre of the manufacturer. In the absence of a tester it is possible to take advantage of a stroboscope of compensatory or usual types. In the first case the corner of an advancing of ignition is defined on a scale of a delay of an impulse of illumination at combination of shined labels (the scale of delays in the measurement beginning is exposed on a zero). At use of a usual stroboscope put on a pulley коленвала a label of the moment of ignition. Distance to this label from label ВМТ define under the formula: Distance = 2Р * (the set corner of an advancing rather ВМТ) * r/360, Where Р =3,142, r – pulley radius. 3. On the stopped engine slightly ослабьте a bolt of fastening of the distributor that it could be moved under small effort. 4. Start the engine, establish the necessary turns and direct lamp-flash light on labels. 5. If labels do not coincide, slowly turn the distributor before coincidence of labels on a flywheel and картере (at the left – a label of ignition OT on a flywheel, on the right – a label of ignition OZ on a flywheel). Tighten a bolt of fastening of the distributor and again check up installation of the moment of ignition. Upon termination of clean devices and attach a hose of a vacuum regulator.
