Abstract

Presented is a device for controlling an internal combustion engine operable with at least on of liquid and gaseous fuel. The device includes a rotational speed controller that outputs a control signal, which is dependent on the actual rotational speed of the engine and which influences the power output of the engine. The control signal includes a dimension for the total power to be output by the engine. The device further includes a dividing device configured for receiving the dimension, dividing the dimension for the total power according to a predetermined ratio into a contribution of the liquid fuel and a contribution of the gaseous fuel, and generating and outputting a second and a third control signal. The second control signal influences the liquid fuel quantity injected into the engine per unit time and the third control signal influences the gas fuel quantity injected into the engine per unit time.
