IGNITION
Static ignition
17
The differences between static ignition with two
coils and distributed ignition are:
- the high voltage distributor is no longer used,
- two dual output coils are used.
PRESENTATION
The system comprises:
- the injection computer (the ignition power
stage is integrated into the computer),
- two dual output coils,
- four spark plugs,
- an anti-interference condenser.
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
There are two coils. They are of the dual output
type.
They are controlled separately by the computer.
They create two sparks at the same time.They have a foolproofing device (K7M engine):
- on their base to prevent them being fitted in-
correctly to the rocker box cover,
- at the retaining clips for the high voltage
leads.
They are colour coded on the 3 track electrical
connectors.
Coil (2) has a black electrical connector. This coil
provides the sparks for cylinders 1 and 4 at the
same time. It is controlled by track 28 on the injec-
tion computer.
Coil (3) has a grey electrical connector. This coil
provides the sparks for cylinders 2 and 3 at the
same time. It is controlled by track 29 on the injec-
tion computer.
Both coils are connected to an anti-interference
condenser (1).
