IGNITION SYSTEM
The ignition circuit is the static advance inductive discharge type. The power module is outside of the
control unit, whilst the high tension is supplied by four ignition coils fitted directly on the spark plugs
(top-plug type coils).
The primary winding for each coil is supplied by the battery voltage via the system relay and is connect-
ed to the control module for connection to earth.
The optimum ignition advance is calculated by the control unit depending on the engine speed and load
and is implemented in the form of the time between the moment in which the primary circuit supply is
interrupted and the explosion stroke T D C .
