The system is made up of:
- electronic control unit;
- double ignition coil;
- four sparking plugs;
- spark plugs.
DES CRIPT IO N OF FUNCT IO NING PRINCI PL E
Accordi ng to the data received from
various sensors, but essentially according
to the revolution ratio and the load of t he
engine, the electronic control uni t will de-
termine the ignition advance; it will also
identify the cylinders that are set at the
upper center point and, consequently, will
command the re spective coil. This c auses the spark at the level of the
two cylinders t hat are at the upper center
point, thus interrupting the m ass-setting of
the respective coil. T
HE CO IL
The system c ontains a doubl e c oil, con-
trolled by the calculator.
Coil no. 2 has an electric connector (1) with
four ways, whi ch si m ultaneousl y produc e
s parks at cylinders nos. 1 and 4, when it i s
commanded by pin no. 32 of the i njection cal-
culator, and on cylinders no. 2 and 3 when it
is commanded by pi n no. 1 of the same cal-
culator.
