    Abstract: A Dual-fuel combustion engine, possessing: a control device at least one combustion chamber at least one gas supply device for supplying a gaseous fuel to at least one combustion chamber, and at least one injector for injecting liquid fuel into the at least one combustion chamber, and which injector is controllable through a control device by the use of an actuator triggering signal, for which at least one injector possesses an output opening for the liquid fuel, which is closable by means of a needle (6), and for which the control device regulates through the use of the actuator triggering signal, the opening of the needle (6) in the ballistic region of the needle in a pilot operating mode of the combustion engine to which end, an algorithm is stored in the control device, which receives, as input values, at least the actuator triggering signal (Δt) and, using an injector model, calculates the mass of liquid fuel introduced via the output opening of the injector, and which compares the mass calculated by means of the injector model with a required target value (mdref) of the mass of liquid fuel, and on the basis of the result of such comparison, either leaves the actuator triggering signal (Δt) unchanged or corrects it, and a process for the operation of a combustion engine and of an injector.

    IPC: F02D19/06

    Abstract: Dual-fuel internal combustion engine with at least two combustion chambers which have a different distance from at least one gas mixer for producing a gas-air mixture, whereby an inlet valve for the gas-air mixture and an injector for liquid fuel is assigned to each of the combustion chambers, and a control device is provided which is configured in a change-over mode to change an amount of energy supplied to the at least two combustion chambers through the gas-air mixture in a first direction, and to change an amount of liquid fuel supplied to the at least two combustion chambers in an opposite, second direction, whereby the control device is designed to determine a time for the change of the amount of liquid fuel in the second direction for each of the at least two combustion chambers according to the distance of the respective combustion chamber from the at least one gas mixer.

    IPC: F02D41/00 ,  F02D41/40

    Abstract: A dual-fuel internal combustion engine with at least one combustion chamber, wherein the at least one combustion chamber is assigned to an intake valve for a gas-air mixture and an injector (I1 to I4) for liquid fuel, and a control device, which is designed in a switch-over mode to perform a switch-over, that an amount of energy supplied to the at least one combustion chamber through the gas-air mixture is changed, and a supplied amount of liquid fuel and/or a time of the injection of the liquid fuel is changed, and a combustion sensor whose signals are characteristic for the combustion process occurring in the at least one combustion chamber, wherein the control device is designed to carry out the switch-over using a stored relationship between a time progression of the signals of the combustion sensor and an introduced amount of gas-air mixture.
