DescriptionAn electronic management system supervises and governs all engine parameters. It optimises performance and fuel consumption by responding in real time to different service conditions.The Diesel engine is fitted with a COMMON RAIL UNIJET injection system.This features the use of high, electronically-controlled injection pressure. Fuel delivery, termed a pilot injection, is optimised by the electronic control unit via the injector and not managed by the pump.The common rail injection system on this version with 4 valves per cylinder uses Multijet technology: i.e. it carries out more than the usual two injections during each engine cycle: it carries out two pre-injections (before the piston is at TDC), one main injection and two post-injections.This solution improves consumption, emissions, quietness and performance because it allows better control of the temperature in the combustion chamber, lowering the maximum value and extending the optimum combustion zone.The system uses signals received from numerous sensors to control actuators. It is connected to the following systems:fuel supply;air supply system;heater plugs;accelerator pedal;engine cooling;fuel preheating. For greater detail, see 3308489Characteristic of working principle1060DIESEL FUEL INJECTION . Thanks to the electronic management described above, this engine conforms to the latest anti-pollution and continuous control regulations in accordance with the EOBD system (European On Board Diagnosis); The EOBD (European On Board Diagnosis) system carries out continuous diagnosis of the car's petrol fuel system components relating to emissions and indicates any deterioration of these components by the warning light in the instrument panel coming on.The aim of the system is:keeping the efficiency of the system under control;signalling an increase in emissions due to a vehicle malfunction;signalling the need to replace components which have deteriorated.The system is controlled by means of special relays located in the engine compartment unit; the supply lines to the control unit and the various system components (sensors and actuators) are protected by special fuses, also located in the engine compartment.Glow plug preheating is protected by a dedicated fuse located in the engine compartment junction unit.
Functional description The engine control unit M10 monitors and controls the entire electronic ignition and injection system. The supply controlled by the ignition (15/54) reaches pin 28 of connector A of M10 from the line protected by fuse F16 of junction unit B2.The main injection relay T9 of B1 controls the entire system; the supply line is protected by fuse F18 of B1; it is energized by a control signal (earth) coming from pin 72 of the control unit M10, and thus sends a supply:to pin 1 of connector A of the actual control unit, via the line from fuse F17 of B1;to pin 5 of connector A of the actual control unit, via the line from fuse F22 of B1;to the heater K100, to the air flow meter K41, to the solenoid valves L30, L36;L62, to the control unit M15, via the line from fuse F11 of B1 The fuel pump relay T10 of B1 is supplied from the line of fuse F21 of B1. It is energized by a control signal (earth) from pin 91 of connector A of control unit M10 and supplies power to fuel pump N40, which is earthed through the inertia switch I50, which cuts off the circuit in the case of a crash and so prevents the dangerous spilling of fuel. Pins 2, 4 and 6 of connector A of M10 are earthed. The diesel pre-heating relay T19 of B1 is supplied by the line for fuse F20 of B1. It is energized by a control signal (earth) coming from pin 68 of connector A of the control unit M10 and supplies power to the diesel heating resistance inside sensor K100. Control unit M15, which manages preheating of spark plugs A40, is supplied connetor C directly from the battery via a lline protected by fuse F1 of B1. It is supplied, connector A, by the line for fuse F11 of B1 and exchanges command and control signals with pins 52 and 93 of connector A of M10 which controls the timing. Connector B is connected to the heater plugs A40 . The engine control unit M10 receives signals from the various sensors in order to monitor all engine service conditions. Rpm sensor K46 supplies information on engine speed via a frequency signal sent to pins 12 and 27 of connector B of control unit M10. Timing sensor K47 is supplied from pin 11 of connector B of control unit M10. It receives a reference earth from pin 20 of connector B of control unit M10 and sends it a signal of frequency corresponding to the timing of pin 50 of the same connector. The engine temperature sensor K36 , receives a reference earth from pin 41 of the control unit M10 and supplies a signal proportional to the temperature of the engine coolant to pin 58 of connector B. The same sender unit also supplies information to the temperature gauge and warning light 3309717SeeE4010INSTRUMENT PANEL . The air flow meter K41 receives a power supply from the line for fuse F11 of B1 and a reference earth from pin 44 of connector B of M10. It is supplied by the control unit from pin 29 of connector B of M10, and sends pin 42 of connector B a signal proportional to the air flow. There is also an air temperature sensor inside K41 which sends an air temperature signal to pin 37 of connector B of M10. Accelerator pedal K55 is fitted with two built-in potentiometers (a main one and a safety back-up). The former receives power and earth from pins 30 and 45, respectively of connector A of M10 and sends a corresponding signal to pin 9. The latter receives power and earth from pins 46 and 8, respectively of connector A of M10 and sends a signal to pin 31. The fuel temperature sensor K100 measures the temperature of the diesel entering. It receives a reference earth from pin 10 of connector A of M10 and sends the fuel temperature signal to pin 11. The supercharging sensor K82 measures the pressure and temperature in the intake chamber, downstream of the turbocharger. It is supplied from pin 13 of connector B of M10 and receives a reference earth from pin 23 of connector B. The signal corresponding to the pressure value is sent to pin 40 of connector B of the control unit. There is also an air temperature sensor inside K82 which sends a signal to pin 53 of connector B of M10. The fuel pressure sensor K83 is responsible for providing the injection control unit with a feedback signal for governing pressure and injection duration. It receives power and a reference earth from pins 28 and 8 respectively of connector B of M10; it then sends the pressure signal to pin 43. The switch I30 N.A. contact is supplied when the ignition is turned on (15/54) from fuse line F1 of junction unit B2: when the brake pedal is pressed, the switch closes and sends the operation signal to pin 27 of connector A of M10. The same signal for the brake pedal I30 is also used for operating the brake lights SeeE2021 BRAKE LIGHTS . 767 the second contact for the brake pedal I30, N.C. contact, receives an ignition-controlled supply (15/54) from the line protected by fuse F9 of the junction unit B2; when the brake pedal is released, the switch sends a signal to pin 80 of connector A of M10. Pin 79 of connector A of M10 receives the signal coming from the clutch switch I31. The fuel pressure regulator N77 has the task of keeping the value of the fuel pressure in the accumulator constant. The two control signals come from pins 4 and 34 of connector B of the control unit M10. The EGR solenoid L30 controls exhaust gas recirculation. is supplied by the line for fuse F11 of B1; and is controlled by a signal from pin 60 of connector B of M10. The variable geometry solenoid valve L36 regulates the operation of the turbine according to the engine load: it is supplied by the line for fuse F11 of B1; and is controlled by a signal for pin 15 of connector B of M10. The solenoid valve on the throttle casing L62 shutters and closes the throttle, for example when the engine is switched off; it is supplied by the line for fuse F11 of B1 and is controlled by a signal for pin 59 of connector B of M10. The engine management control unit sends the command to the injectors N70 from pins 16-47, 2-31, 1-46, 17-33 and 18-48 of connector B of M10 for cylinders 1, 2, 3 , 4 and 5, respectively. The control unit M10 converses with the ABS control unit M50 via CAN line pins 61 and 62 of connector A. The control unit M10 also receives the speedometer signal via this CAN line. This signal is also sent discretely from the instrument panel (pin 5 of connector B) to pin 49 of M10.3309717SeeE4010INSTRUMENT PANEL . The control unit M10 is connected to the ALFA ROMEO CODE control unit via a line from pin 47 of connector A SeeE7010 CODE . The control unit is equipped with a self-diagnostic system that may be used by connecting the unit to connector R10: this receives signals from pin 25 of control unit M10 through the tester line.3310073SeeE8010DIAGNOSTIC MULTIPLE CONNECTOR The self-test system of the control unit M10 also generates a signal - which comes from pin 71 of connector A - which is connected directly to the 'EOBD' warning light located in the instrument panel E50 pin 11 of connector A; a 'pre-heating signal' is sent to pin 2 of connector A of E50 from pin 92 of connector A of M10. Control unit M10 sends out a signal proportional to engine rpm from pin 48 of connector A. An engine temperature signal is sent from pin 94 of connector A of M10 SeeE4010 INSTRUMENT PANEL . Control unit M10 is connected to the air conditioning system via pins 28 and 54 of connector A. This allows engine idling speed to be adjusted to increased engine load whenever the compressor is activated, or to turn off the compressor in the case of high speeds or high engine loads SeeE6021 COMPRESSOR ENGAGEMENT . The control unit also controls the engine cooling system: pins 69, 42, 81 and 90 of connector A control the engagement of the relevant fan 3309782SeeE5020ENGINE COOLING .
