3234532 - E5030 PETROL ENGINE ELECTRONIC MANAGEMENT - Description (Smart gearbox)
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 catalytic converter;
- fuel vapour recirculation.
On this version, the engine is fitted with
a throttle body controlled electronically by the control unit. Special
software inside the control unit computes throttle opening. This
system does away with a connection between accelerator and throttle
body.The control unit also controls the hydraulic
variable valve timing - an exclusive system adopted on T. SPARK
engines.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.

.
The system is also controlled by means of
special relays located in the engine compartment near the battery.The supply lines to the control unit and
the various system components (sensors and actuators) are protected
by a specific maxifuse and other jumper fuses located next to the
junction unit.
