192004591 - 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;
• 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: 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.This version also features a variable geometry intake system that is controlled by the injection control unit according to engine service conditions.The control unit also manages the electro-hydraulic phase transformer.The electronic management system described above ensures that this engine meets the very latest EOBD (European On Board Diagnogis) system emission control and monitoring requirements. This system allows continous diagnosis of emission-related car components and notifies the driver if any of the components should deteriorate by turning on a warning light in the instrument panel.For more details, see    See descriptions 1056 PETROL INJECTION SYSTEM.The system is also controlled by dedicated relays in the engine bay control unit. Lines supplying the control unit and various system components (sensors and actuators) are protected by dedicated fuses that are also located inside the engine bay.
