Abstract (en)

[origin: CA3002559A1] The invention relates to a dual-fuel internal combustion engine comprising: a regulating device; at least one combustion chamber; at least one gas supply device for supplying a gaseous fuel to the at least one combustion chamber; and at least one injector for injecting liquid fuel into the at least one combustion chamber, which can be regulated by the regulating device by means of an actuator control signal, the regulating device regulating an opening of the needle of the injector in the ballistic region of the needle, in a pilot operating mode of the internal combustion engine, by means of the actuator control signal. An algorithm is provided in the regulating device, which receives at least the actuator control signal (?t) as an input variable and calculates a position of the needle (6) by means of an injector model, compares said position with a needle position set point value (zref), and corrects the actuator control signal (?t) according to the result of the comparison. The invention also relates to a method for operating such an internal combustion engine and to an injector of such an internal combustion engine.
