THE GENERAL DATA

The switchboard


The switchboard serves for strengthening of the signal arising at the moment of disappearance of effect of the Hall, operates interruption of a primary contour of the coil of ignition, and also corrects time of occurrence of effect of the Hall depending on number of turns of the engine, keeping, thus almost constant size of energy of a spark of ignition.

In engines 1,6 дм3 the system of ignition of firm Lucas in which the distributor of ignition has no regulators of a corner of an advancing of ignition is used. This function is carried out by the switchboard on the basis of signals about number of turns of the engine and depression in its inlet collector.
