DESCRIPTIONAn electronic control system supervises and manages all engine parameters to optimise performance and fuel consumption by means of a real-time response to different operating conditions. The system is managed by a single control unit which controls both ignition and injection. This version is equipped with a FIRE Turbo engine, derived from the aspirated FIRE 1.4 16V engine. Turbocharging is provided by a fixed geometry turbocharger and is managed by the Powertrain Control Module through a turbo pressure solenoid valve that regulates the wastegate and a shut-off solenoid valve. Depending on the signals received from numerous sensors, the control unit manages the injectors connected to it, handling the following systems:
The throttle body is also controlled electronically by the control unit: the throttle opening is calculated according to a specific logic inside the Powertrain Control Module; the mechanical connection between the accelerator pedal and the throttle body is thereby eliminated. Due 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 relay switches 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 in the engine compartment junction unit. |
