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

GENERAL INFORMATION

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

Labels for installation of ignition are put on a flywheel (are visible through an aperture in a bell-shaped case of a check point) and / or on a pulley-uspokoitele on a crankshaft sock.


Prevention

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


Opening in a bell-shaped case of a check point for illumination by a stroboscope at ignition installation


PERFORMANCE ORDER
1. Disconnect a hose of a vacuum regulator.
2. Connect a tachometer and a stroboscope, being guided by the instruction of the manufacturer of devices. It is recommended to apply a stroboscope with the induction sensor. As a rule, conclusions of a food of a stroboscope join battery poles, and a sensor conclusion – to a wire of a candle of the 1st cylinder.

Prevention

On a part of cars for check and installation of the moment of ignition the VMT sensor (the label of the moment of ignition in these cars as a rule is absent) for which the special tester which joins in the diagnostic socket is intended is provided. The tester is used in car-care center of the manufacturer. In the absence of a tester it is possible to use a stroboscope of compensatory or usual types. In the first case the corner of an advancing of ignition is determined by a scale of a delay of an impulse of illumination at combination of shined labels (the scale of delays at the beginning of measurement is exposed on a zero). When using a usual stroboscope put on a crankshaft pulley a label of the moment of ignition. Distance to this label from a label of VMT determine by a formula:
Distance = 2Р * (the set corner of an advancing VMT is relative) * r/360,
where R =3,142, r – pulley radius.


3. On the stopped engine slightly weaken 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 a case (at the left – a label of ignition of OT on a flywheel, on the right – a label of ignition of OZ on a flywheel). Tighten a bolt of fastening of the distributor and again check installation of the moment of ignition. Upon termination of clean devices and attach a hose of a vacuum regulator.
