摘要： The invention relates to a method for dosing fuel using a fuel-injection valve (1) especially an injection valve for fuel injection internal combustion engines (3). It comprises one piezoelectric or magnetorestrictive actuator (16) and a valve-closing body (14) controlled by valve lift (h) in the actuator (16). Said valve-closing body co-operates with a valve surface (13) in the valve body (11) to provide an air-tight seat. In order to generate variable fuel flow (Q) in the air-tight seat, the valve lift (h) can be variably regulated depending on variable control signal that controls the actuator (16). In order to obtain a compensating curve, the fuel flow (Q) of the fuel spray (40) injected by the fuel injection valve (1) is measured depending on the control signal to generate a compensating curve (46). A predetermined fuel flow (40) is regulated with the control signal using the compensating curve (46).

摘要： The invention relates to a method and device for the control of a solenoid valve for fuel injection in an internal combustion engine. The control phase thereof is divided into an operating phase (TA), during which the one valve needle of the solenoid valve is held open by a current (IA), flowing through the solenoid coil thereof and a hold phase (TH), during which the valve needle is held open by a second, lower current (IH), flowing through the solenoid coil. At least once at the beginning of the operating phase (TA), a booster phase (B1) is activated, whereby a pulse shaped booster current (IBOOST) flows through the solenoid coil from a booster condenser charged to a high voltage (UBOOST). The invention is characterised in that, during the control phase of the solenoid valve, several booster impulses (B1, B21, B22) are activated sequentially, at freely selectable times during the control phase.

摘要： The invention relates to a method for operating a heatable exhaust sensor (20), which provides at least one measurement signal (26) and in which a sensor heater (24) is operated by an impulse width modulated operating voltage (28), and to devices for carrying out the method. The procedure according to the invention is characterized in that detecting the at least one measurement signal (26) has precedence over the providing of the impulse width modulated operating voltage (28) for the sensor heater (24) and that, at least during a specified measurement window (30, 32) in which the measurement signal (26) is detected, the providing of the impulse width modulated operating voltage (28) for the sensor heater (24) is suppressed by a blocking signal (18).
