3023489 - E5030 PETROL ENGINE ELECTRONIC MANAGEMENT - Description (120 CV)
Description
An electronic management system supervises
and governs all engine parameters. It optimises performance and
fuel consumption by responding in real time to different service conditions.The system is managed by a single control
unit that controls the twin spark ignition (static and lost spark),
and the injection (phased).The system uses signals received
from numerous sensors to control actuators. It is connected to the
following systems:
- fuel supply;
- air supply:
- accelerator pedal;
- engine cooling system;
- exhaust with preconverters and catalytic converter controlled
by three Lambda probes;
- fuel vapour recirculation.
The throttle body is also controlled electrically
by the control unit: special software in the engine management control
unit computes throttle opening; this dispenses with the need for
a mechanical connection between the accelerator pedal and the throttle
body.The control unit also controls the hydraulic
variable valve timing, an exclusive system which allows the intake
timing to be optimised.Thanks to the above-mentioned electronic
management, this engine conforms to the latest anti-pollution and
continuous control regulations in accordance with the EOBD system (European
On Board Diagnosis); this system permits continuous diagnosis of
the vehicle's components relating to emissions, and indicates to
the user, by switching on the relevant warning light on the instrument
panel, any deterioration in these components.

The system is also controlled by means of
special relays located in the engine compartment unit; the supply
lines of the control unit and the system's various components (sensors
and actuators) are protected by specific fuses, in the engine compartment
unit.
