3234528 - E5030 PETROL ENGINE ELECTRONIC MANAGEMENT - Description (Mechanical 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:
• engine cooling system;
• exhaust with catalytic converter;
• fuel vapour recirculation.

The control unit also controls the hydraulic variable valve timing - an exclusive system adopted on T. SPARK engines.This version features the adoption of a variable geometry inlet system, managed by the injection control unit according to the engine operating conditions. For more details,  see DESCRIPTION AND OPERATION: 1056  PETROL INJECTION SYSTEM . 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.
