The need for suitable control of the powerful engine
of the
RSV Mille
led the Aprilia designers to adopt
an electronic management system built into the
engine. All the fondamental operating parameters
are constantly monitored by a sophisticated
electronic controls unit which, on the basis of the
data received, control operation of both the injection
system and the ignition system.
The injectors are fed by a pump which produces a
constant pressure of 330 Kpa. The throttle bodies
have a diameter of 51 mm. Fresh air is taken in
through ducts which make use of dynamic pressure
when the motor-cycle is moving, sending fresh air
into a large volume airbox.
The entire injection/ignition system is also equipped
with a continuous Selfdiagnosis circuit (both on
starting and when the bike is running); this is able to
indicate any malfunctions of the system directly on
the dashboard, without the aid of complicated and
expensive external equipment.
