    摘要: A device for determining a load signal indicating the actual air mass per stroke in an internal combustion engine based on signals which indicate the respective instantaneous air flow rate in the intake pipe, these signals being indirectly or directly summed up over a specified angular range of the crankshaft for forming the load signal. In first predetermined ranges of speeds and throttle-valve positions, the load signal serves directly as a computational basis for the quantity of fuel to be injected. In second predetermined ranges, the last value from the first ranges is subjected to a speed-dependent correction and this corrected value is used as a substitute load signal.
