    摘要: Disclosed is a method for operating a fuel injector comprising at least one injection port controlled by an injector needle, wherein pressure variations when the injector needle is opened and/or closed are determined using a sensor. Said method is characterized in that in order to determine the opening/closing time of the injector needle, a variable characterizing the speed of sound is measured by opening and/or closing a shock wave, and the wave propagation time by which the opening/closing time of the needle or valve is corrected is deduced therefrom.

    摘要: The purpose of the present invention is to detect variations between the quantities of fuel injected into cylinders by fuel injection devices and correct the fuel injection quantity variation while minimizing the computational load on a drive device and the level of performance required of a pressure sensor. A drive device for fuel injection devices according to the present invention performs control wherein movable valves are driven so that predetermined quantities of fuel are injected by applying, for the duration of a set energization time, a current that will reach an energization current to solenoids of a plurality of fuel injection devices which open/close fuel flow paths. The drive device is characterized in that the set energization time or energization current is corrected on the basis of a pressure detection value from a pressure sensor that is attached to a fuel supply pipe disposed upstream of the plurality of fuel injection devices.

    摘要: The invention relates to a method for controlling an internal combustion engine (3), wherein a first engine control device (5) generates at least one control signal in order to actuate at least one function of the internal combustion engine (3). The method is characterized in that a switchover device (9) transmits the at least one control signal of the first engine control device (5) to the internal combustion engine (3) in order to actuate the at least one function of the internal combustion engine (3). The first engine control device (5) continuously or periodically transmits a sign-of-life signal which indicates the functionality of the engine control device to the switchover device (9). The first engine control device (5) does not transmit the sign-of-life signal or transmits the signal incorrectly if a fault occurs which endangers the proper actuation of the at least one function of the internal combustion engine (3) by means of the first engine control device (5). If the sign-of-life signal of the first engine control device (5) is not received or is incorrectly received by the switchover device (9), the switchover device (9) stops transmitting the control signals of the first engine control device (5) to the internal combustion engine (3) and starts transmitting at least one control signal generated by a second engine control device (7), in order to actuate the at least one function of the internal combustion engine (3), to the internal combustion engine (3).
