3309847 - 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 system;
accelerator pedal;
engine cooling;
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: 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.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 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. For more details Characteristic of working principle 1056 PETROL INJECTION SYSTEMThe system is 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.
