摘要： A method and device for driving an injector in an internal combustion engine in which a current wave which is variable over time, which comprises an initial section substantially of a pulse type and having a relatively high current intensity, an intermediate section during which the current intensity is rapidly reduced to substantially zero values and a final section having a substantially constant and relatively low current intensity, is caused to circulate through a control circuit of the injector.

摘要： A method for control of an injector in an internal combustion engine in which for a specific engine cycle, a control unit calculates a desired value of the opening time of the injector and forwards this desired value to a drive circuit of the injector, a supervision device calculates an actual value of the opening time of the injector during the injection phase, compares this actual value with the desired value and generates an error signal if the difference between the desired value and the actual value is outside a predetermined acceptability range.

摘要： The device includes a circuit for generating signals indicative of a reference current which is variable in steps and, during successive time intervals defined by a clock-signal generator, decreases according to respective predetermined functions as the voltage detected across the lamp increases, these functions corresponding substantially to respective predefined constant values of the power supplied to the lamp, and a differential comparator circuit which compares the values of the reference current generated with the current detected in the lamp and generates an error signal in dependence on the difference between them. The error signal can be used to control the device for supplying the lamp.

摘要： The circuit including a capacitor which is alternately discharged and charged in synchronism with the signal which develops across the terminals of a resistor operating to detect the current in the lamp. A sawtooth wave form is thus obtained, which is compared with a threshold level which is varied in dependence on the current which it is necessary to provide to the lamp. On the basis of this comparison logic signals are produced which are utilized to control the power switches of the inverter which controls the lamp.

摘要： The circuit comprises a switched dc/dc converter of the "fly-back" type, a second switched dc/dc converter of the "feed-forward" type, an H-shaped bridge switching circuit which is connected to the dc/dc converters and in the central branch of which the discharge lamp and an associated reactive starter device are disposed, and a control circuit which can drive the dc/dc converters and the bridge switching circuit in a manner such that, each time the lamp is switched on, a very high voltage is applied initially, in particular, in order to start the lamp, and subsequently a low voltage is applied, but with a high electrical power, in order to support the passage of a large current through the lamp during the heating (warming-up) of the lamp and during the subsequent steady operation of the lamp.
