TECHNICAL DESCRIPTION
DIGITAL ELECTRONIC IGNITION
155
Your engine is equipped with a digital
electronic ignition system with knock
sensor. The system is
capable of
adjusting the ignition timing
automatically to cope with fuels of
different anti-knock properties. This
makes it possible to use unleaded
premium fuel with 95 RON (91 AKI)
1)
and
if not available, it may also use regular
unleaded fuel with a minimum of 91 RON
(87 AKI)
1)
.
The correct timing for optimum efficiency
under all engine operating conditions is
calculated by a "timing map" stored in the
system's memory. The timing map con-
tains the ignition timing values for any
particular engine rpm and throttle openi-
ng.
