2428073 - E5030 PETROL ENGINE ELECTRONIC MANAGEMENT - Description
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 which controls both the ignition and the injection.The system uses signals received
from numerous sensors to control actuators. It is connected to the
following systems:
- fuel supply;
- air supply system;
- accelerator pedal;
- engine cooling;
- control of combustion - Lambda sensors
- control of exhaust with catalytic silencer.
- fuel vapour recirculation.
The throttle body is also controlled electronically
by the control unit: specific 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.Thanks to the electronic management described
above, this engine conforms to the latest anti-pollution and continuous
control regulations in accordance with the EOBD (European On Board
Diagnosis) system; this system permits continuous diagnosis of the vehicle
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 to the control unit and the various system components (sensors and
actuators) are protected by special fuses, also located in the engine
compartment.
