1. An electronic control device for internal combustion engines with high-power output, characterized by a first desired value means for setting a desired rotational speed for the internal combustion engine, a second desired value means for setting a desired fuel quantity filling value for the internal combustion engine, means for comparing the desired-value and actual-value of the rotational speed, first pure rotational-speed control means with P-I-D behavior responsive to the output of said rotational speed comparing means, second fuel quantity filling-rotational speed control means responsive to the output of said second desired-value means, means for selectively engaging as a control stage one of said first and second control means, means for providing a fuel quantity filling limit signal, second means for comparing the output signal of the selected first and second control means with the fuel quantity filling signal, and providing an output of the respective smaller signal, and adjusting means responsive to the second comparing means for controlling the fuel quantity filling of the internal combustion engine in accordance with the smaller signal.
