Description - PETROL ENGINES ELECTRONIC MANAGEMENT - Fiat STILO 2.4 20v Fino a 06/02


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 sensorscontrol of exhaust with catalytic silencerfuel 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.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.

Operational description - PETROL ENGINES ELECTRONIC MANAGEMENT - Fiat STILO 2.4 20v Fino a 06/02


The engine management control unit M10 controls and governs the entire electronic ignition and injection system.The control unit M10 is supplied directly by the battery at pin 15 of connector A via a line protected by fuse F18 of the engine compartment junction unit B1The ignition-operated power supply (15/54) arrives via a line protected by fuse F16 of the engine compartment junction unit B1 at pin 47 of connector A of M10 .Main injection relay T9 of B1 controls the entire system: t is energized by an control signal (earth) from pin 31 of connector A of engine control unit M010 and then forwards a power supply:to injectors N70 and coils A30 , via a line protected by fuse F22 of B1 ;to the fuel vapour recovery solenoid valves L10 and variable geometry L15, to the phase transformer actuator N76 and to the Lambda sensors K15 and K17 to the flow meter K41, via the line protected by fuse F11 of B1at pins 16 and 32 of connector A of the control unit, via the line of fuseF17 of B1 .Fuel pump relay T10 of B1 is supplied by a line from fuse F21 of B1 .This is excited by a command signal (earth) from pin 30 of connector A of control unit M10 and supplies power to fuel pump N40 , which is earthed via inertia switch I50 , that cuts off the circuit in the case of impact and thus prevents dangerous outflows of fuel.
