192004576 - 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:
- accelerator pedal;
- engine cooling system;
- 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; 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.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.For greater detail, see See descriptions 1056 PETROL INJECTION SYSTEM.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.
