摘要： A method and device for triggering a solenoid valve for injecting fuel into an internal combustion engine is described. The triggering phase of the solenoid valve is subdivided into a pull-up phase and a holding phase. During the pull-up phase, a valve needle of the solenoid valve is caused to open by a first current intensity flowing through a magnetic coil of the solenoid valve. During the holding phase, the valve needle is held in the open state by a second, lower current intensity flowing through the magnetic coil. At least once at the beginning of the pull-up phase, a booster phase is activated during which a pulse-shaped booster current from a booster capacitor charged to a high voltage flows through the magnetic coil. During the triggering phase of the solenoid valve, a plurality of booster pulses are activated in succession, whose time position within the triggering phase is freely selectable.

摘要： To prevent stumbling operation of an internal combustion (IC) engine (E) during warm-up due to switching back-and-forth between control of the air-fuel composition of the mixture being applied to the engine based on a preset, rich mixture and controlled by a lambda sensor, the lambda sensor internal resistance is sensed and, when the internal resistance of the lambda sensor, when exposed to a rich mixture, is substantially less than when exposed to a fuel-lean mixture, an indication is thereby provided that the sensor has reached proper operating temperatures - see FIG. 3 - is capable of providing output voltages within the evaluation range of two threshold circuits (9, 10) which receive reference values from a voltage divider (6, 7, 8) and of resuming control based on the output voltages of the sensor. The minimum operating temperatures of the sensor are asymmetrical, with respect to lean or rich air-fuel mixtures being applied to the engine, to permit either uninterrupted control of the engine in accordance with a preset air-fuel mixture during warm-up or only by the sensor, after it has reached its operating temperature, thereby preventing back-and-forth switching between control based on the preset conditions and on output signals from the sensor.

摘要： A method for determining a polarization of a pump cell and/or a Nernst cell of a lambda probe for the diagnosis of the broadband lambda probe. A voltage or current pulse is applied to the pump/Nernst cell in a first method task, and, in a second method task, a voltage at the pump cell and/or the Nernst cell, or a variable that is related to the polarization or its time characteristic is determined and used as a measure of the polarization, and the function of the broadband lambda probe is monitored via the ascertained polarization. The determination of the polarization may be performed as a voltage measurement performed once or multiple times, or by determining the effect of the polarization in an associated controller, such as a pump current controller of an engine control unit. The variable associated with the polarization may be the reaction of the pump current control.

摘要： A method of metering fuel with a fuel injector, in particular a fuel injector for fuel injection systems in internal combustion engines is described, having a piezoelectric or magnetostrictive actuator and a valve closing body which is operable by the actuator with a valve lift, cooperating with a valve seat face provided on a valve seat body to form a sealing seat. The valve lift may be adjusted variably as a function of a variable control signal triggering an actuator to produce a variable fuel flow at the sealing seat. To produce afitted curve, the fuel flow of the fuel jet sprayed by the fuel injector is measured as a function of the control signal to produce a fitted curve, and a predetermined fuel flow is set with the control signal by using the fitted curve.
