125002414 - E5030 PETROL ENGINE ELECTRONIC MANAGEMENT - DESCRIPTION

Description

An electronic control system supervises and governs all engine parameters to optimise performance and fuel consumption by means of a real-time response to different service conditions.The system is managed by a single control unit which controls both ignition and injection.

Depending on the signals received from numerous sensors, the control unit controls the injectors connected to it managing the following systems:

• fuel supply;
• air supply;
• accelerator pedal;
• engine cooling;
• exhaust with catalytic preconverters and two catalytic converters controlled by four lambda sensors;
• fuel vapour recirculation.

The throttle body is also controlled electronically by the control unit: throttle opening is calculated in accordance with specific software mapped inside the engine control unit. This system does away with the need for a mechanical link between accelerator pedal and throttle body.The electronic management system described above ensures that this engine complies with the toughest emission control regulations and acts as a continuous EOBD monitoring system.For more details    Characteristic of working principle 1056 PETROL INJECTION SYSTEMThe system is also controlled by two relays located in the engine compartment junction unit.The supply lines to the control unit and the various system components (sensors and actuators) are protected by a maxifuse and other fuses, located in the engine compartment fuse control unit.
