199004722 - 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.This version is equipped with a FIRE Turbo power unit, derived from the aspirated FIRE 1.4 16V engine. Turbocharging is provided by a fixed-geometry turbocharger and is managed by the engine management control unit via a turbo pressure solenoid that regulates the waste gate and shut-off solenoid.

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;
  • combustion control - Lambda sensors;
  • control of exhaust with catalytic converter;
  • fuel vapour recirculation;
  • turbocharging pressure adjustment.
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.Thanks to the electronic management described above, this engine conforms to the most recent emission control regulations (EURO 4).For more details    See descriptions 1056 PETROL INJECTION SYSTEM The system is also controlled by dedicated relays in the engine compartment 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 compartment control unit.
