16.11.7.1. Check of installation of the moment of ignition

 PERFORMANCE ORDER

On a forward cover of the block of cylinders there are three tags in the form of inflows.

The first tag on the course of rotation of a pulley of a bent shaft corresponds 10 ° ignition advancings, the second – 5 ° and the third tag, the longest – 0 °.

On a pulley of a bent shaft the tag of the top dead point (TDP) of the first cylinder is beaten out. At a pulley end face in this place there is an inflow.

If earlier adjustment of a corner of an advancing of ignition on a scale an octane proofreader was carried out, we install the distributor case in zero situation an octane proofreader (see Correction of a corner of an advancing of ignition).
We connect one probe of a control lamp or the voltmeter to contact of low voltage of the distributor, and the second on "weight" and we include ignition. At the opened contacts of the breaker the lamp has to burn, and the voltmeter – to show presence of tension.
Special key for a nut of a pulley we turn a bent shaft before fire of a lamp. If there is no such key, hang out one of back wheels and, having included direct transfer, we rotate it, turning a bent shaft. The lit-up lamp indicates the ignition moment. We check combination of a tag on a pulley with a long tag on a forward cover of the block of cylinders. At discrepancy of tags we regulate the moment of installation of ignition.

Initial corner of an advancing of ignition when using gasoline with octane number 93 and 95 - 5 ° (an average tag on a forward cover of the block of cylinders).
