169002435 - E5030 PETROL ENGINE ELECTRONIC MANAGEMENT - DESCRIPTION (POWERED THROTTLE)
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).The "Drive by Wire" system eliminates the mechanical connection between the accelerator pedal and the throttle casing, allowing the torque supply to be improved according to the differing driver requirements translating them into benefits for the customer in terms of driveability and consumption.The brilliant performance of these power units is improved by a specially developed electronic control system based on a miniature Magneti Marelli electronic control unit produced using micro-hybrid technology capable of conversing with the vehicle''s electronic devices via serial lines.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.
