摘要： A fuel injector assembly includes a plurality of fuel injectors (22), each of which may have a different performance characteristic. After the performance characteristics have been determined, an internal, energizable voltage or current source (28) is provided within the injector housing (23). Each time the vehicle ignition is turned on, a controller (26) queries each injector (22) to obtain a signal from the individual, internal, energizable voltage or current sources (28). The controller (26) then uses the output of the internal voltage or current source (28) as an indication of the performance characteristics of each injector (22). The controller then customizes the power signal supplied to each injector to accommodate for different performance characteristics.

摘要： Using a control coil having a high response characteristic suited to the valve opening and a hold coil suited to a hold to be held a large force by a small large current, during the valve opening time a high voltage is applied to the control coil suited to the valve opening and during a valve opening hold time a low and stabilized voltage is applied to the hold coil suite to the holding, and then a valve body driven. In a fuel injection apparatus, a drive manner during a valve opening time and a hold time is optimized.

摘要： A method for determining the control voltage for a piezoelectric actuator of an injection valve in which at first the pressure in a hydraulic coupler is measured indirectly, before the next injection process. The pressure is measured since the piezoelectric actuator is mechanically coupled to the hydraulic coupler, so that the pressure induces a corresponding piezo voltage in the actuator. This induced voltage is used before the next injection process for correcting the control voltage for the actuator. Too low an induced voltage is valued as a fault for recognizing an intermittent injection operation. The injection valve may be used for a common rail system for fuel injection in a gasoline or diesel engine.

摘要： A fuel injection system for an internal combustion engine capable of being normally operated while using an output of a generator driven by the internal combustion engine as a power supply therefor. The system includes a switching circuit for switching a driving current fed to an injector from a main power circuit which uses the output of the generator as a power supply therefor. The switching circuit is controlled by a switch control circuit for which a power supply comprises a control power circuit. The control power circuit includes a storage unit for storing electric power therein, so that the storage unit may be act as a power supply when the output of the main power circuit is reduced, to thereby feed the switch control circuit with a power supply voltage of a level equal to or above an operable level. The storage unit is charged by the output of the main power circuit or an output of a generating coil for a control power supply provided in the generator in a manner to be separate from a generating coil for the main power supply.

摘要： During the piloting of the load, the current intensity and the voltage present in the load are monitored by the comparison of their values with a current threshold and with a window of permissible voltage values. When the voltage is outside the window of permissible values and/or the current falls below its threshold, a fault message is generated and the nature of the fault (open load, short circuit to earth, short circuit to the supply voltage) is also identified by the emission of a corresponding signal of a diagnostic nature. The identification of the faulty stage or stages is also provided for in the case of a circuit including several stages in parallel.

摘要： Inductor coil (13) of a relay (12) used to supply battery power to a power load (11) of a vehicle engine control system (10) is also used to provide a substantially higher than battery voltage (V.sub.Batt) boost voltage (V.sub.Boost) for vehicle control apparatus (20). Microprocessor (21) generates a control signal (V.sub.in) having a 10:1 duty cycle for control of current excitation of the coil (13) during an effective on logic state for the relay (12). During coil current interruptions during the on logic state, energy stored in the inductor (13) is utilized via a rectifier means (26 and 27) to provide the boost voltage. During the on relay state, a movable member (14) of the relay is maintained in its actuated position since current interruptions during the on state are shorter than the relaxation time required for the movable member to assume a nonactuated state. The relay coil generates boost voltage without requiring an additional substantial inductive reactance, and without waiting until the end of the effective on logic state.
