Embodiment Construction
[0018] FIG. 1 shows a block diagram of the main elements of a fuel metering system of an internal combustion engine previously known from DE 199 45 618 A1. Internal combustion engine 10 receives a specific fuel quantity from fuel metering unit 30 at a specific time. Various sensors 40 detect measured values 15 characterizing the operating state of the internal combustion engine and transmit them to the control unit 20 . In addition, different output signals 25 of further sensors 45 are transmitted to the control device 20 . Detected measured value 15 characterizes a state of the fuel metering unit, such as the driver's desire. On the basis of these measured values 15 and further variables 25 , control device 20 calculates a trigger pulse 35 , which is applied to fuel metering unit 30 .
[0019] The internal combustion engine assumed here is preferably a direct-injection and / or self-ignition internal combustion engine. The fuel metering unit 30 can be designed in differe...
