169002430 - 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 that controls the twin ignition (static with lost spark) and the injection (phased).

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;
• engine cooling;
• exhaust with catalytic converter controlled by two lambda sensors;
• fuel vapour recirculation.

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 and showing a message on the instrument panel matrix display.The system is also controlled by dedicated relays in the engine compartment junction unit. Lines supplying the control unit and various system components (sensors and actuators) are protected by dedicated fuses that are also located inside the junction unit.
