3023493 - 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 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 sensors;
- fuel vapour recirculation.
The throttle body is also controlled electronically
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 device which allows the intake
timing to be optimised.This version is also characterized by the
adoption of a variable geometry inlet system, managed by the fuel
injection control unit in accordance with the engine's operating conditions.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 allows continuous diagnosis of the
car 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, in the engine compartment
unit.
