PRESENTATION
The system comprises:
- the injection computer (the ignition power
stage is integrated into the computer),
- two dual output coils, (for the
D7F engine,
these are moulded into one),
- four spark plugs,
- an anti-interference condenser (4).
DESCRIPTION - OPERATING PRINCIPLE
COMPUTER
The injection computer (120), depending on the
information received from various sensors, but
principally depending on the engine speed and
load, determines:
- the number of degrees of advance to be used
and consequently the ignition point,
- which cylinders are at TDC and consequently
the ignition coil to be operated.
The spark is created at the two cylinders at TDC by
cutting the earth to the coil concerned.
COILS (1)
There are two coils. They are of the dual output
type (they cannot be separated in the
D7F en-
gine ).
They are controlled separately by the computer.
They create two sparks simultaneously.
Both coils are connected to an anti-interference
condenser.

Special features of the E7J engine
The coil at (2) has a black electrical connector. It
creates a spark simultaneously at cylinders 1 and
4. It is controlled by track 28 of the injection
computer.
The coil at (3) has a grey electrical connector . It
creates a spark simultaneously at cylinders 2 and
3. It is controlled by track 29 of the injection
computer.
