摘要： An injector has a valve pin whose position is adjustable according to the pressure prevailing in a control chamber and which blocks a fluid flow through at least one injection port in a closed position. The injector has a control chamber that is hydraulically coupled to a high-pressure fluid reservoir, a piezo actuator, and a control valve which hydraulically connects and disconnects the control chamber, the piezo actuator acting upon said control valve. A combination of a triggering period for the piezo actuator and electric power that is to be fed to the piezo actuator is varied from a predefined initial combination to a target combination in which a pressure curve is detected that is characteristic of a movement of the control valve out of the closed position thereof without fluid being proportioned through the injection port.

摘要： A method of driving at least one capacitive actuator with a charge voltage. From a charge quantity .DELTA.Q supplied to the actuator and from the actuator voltage U.sub.p applied to the actuator after the charging operation is terminated, the actuator capacitance is calculated by the equation C.sub.p =.DELTA.Q/U.sub.p. From these values, the energy E.sub.actual =0.5*C.sub.p *U.sub.p.sup.2 =0.5*.DELTA.Q*U.sub.p is calculated. The charge voltage is regulated such that the energy actually supplied is equivalent to a specified desired value.

摘要： A diagnostic method for a soot sensor that lies in an exhaust gas system of an internal combustion engine. First, a first temperature in the exhaust gas system is detected, and it is determined whether the detected first temperature is below a 100° C. If this is the case, a first measured value is then detected with the soot sensor and compared with a specifiable threshold value. If the first measured value exceeds the specifiable threshold value, the soot sensor is determined to be operating properly.

摘要： An internal combustion engine includes at least two cylinders, an intake duct, an exhaust gas section and an exhaust gas recirculation line. The cylinders include a combustion chamber. The intake duct communicates with the combustion chambers via a cylinder inlet channel of the intake duct depending upon a switch position of a gas inlet valve. The exhaust gas section communicates with the combustion chambers depending upon a switch position of at least one gas outlet valve. Exhaust gas is guided back to the inlet channels via the exhaust gas recirculation line dependent upon a switch position of the exhaust gas recirculation valve. To detect a mixing air temperature in the inlet channels, a mixing air temperature sensor is provided. The determined mixing air temperatures are compared. Exhaust gas guided back due to uneven distribution is identified if a difference between the determined mixing air temperature is greater than a predetermined threshold value.

摘要： A method for triggering an electromagnetic consumer with low coil resistance (solenoid for a Diesel injection pump) having a free-running circuit that can be switched over, and an apparatus for performing the method, regulate a voltage at an end stage to a predetermined value. This is accomplished by controlling the control voltage of the end stage during a turn-on phase until a turn-on peak current is reached and then regulating the holding current by repeatedly lowering the current through the end stage and keeping it constant to a predetermined value during a predetermined time period and then raising it again to a maximum value of the holding current until the consumer is turned off.
