    Abstract: A dual-fuel internal combustion engine is provided with at least one combustion chamber assigned to an intake valve for a gas-air mixture and to an injector for liquid fuel. A control device performs a switch-over in a switch-over mode, wherein an amount of energy supplied to the at least one combustion chamber by means of the gas-air mixture is changed, and an injected amount of liquid fuel and/or a time of the injection of the liquid fuel is changed. A sensor provides signals characteristic of occurring knock in the at least one combustion chamber, wherein the control device performs the switch-over with evaluation of the sensor signals. The control device performs the evaluation of the sensor signals based on the injected amount of liquid fuel in the at least one combustion chamber. If knock occurs above a specified first knock threshold value, the control device performs knock-reducing measures if the injected amount of liquid fuel lies below a specified liquid fuel threshold value and/or if knock occurs above a specified first knock threshold value, the control device does not perform knock-reducing measures or performs knock-reducing measures only in a restricted manner if the injected amount of liquid fuel lies above a specified liquid fuel threshold value and if the knock lies below a specified second threshold value.

    Abstract: A dual-fuel internal combustion engine including at least one combustion chamber. The at least one combustion chamber is paired with an inlet valve for a gas-air mixture and an injector for liquid fuel. The internal combustion engine also includes a regulating device which is designed to carry out a switchover in a switchover mode such that a quantity of energy supplied to the at least one combustion chamber by a gas-air mixture is changed, and a quantity of energy supplied to the at least one combustion chamber by the liquid fuel and/or the time of the injection of the liquid fuel is changed. The regulating device is designed to carry out the switchover on the basis of a current load of the dual-fuel internal combustion engine, wherein the regulating device is designed to select an excess air coefficient of the gas-air mixture in the switchover mode, the coefficient being larger than a target excess air coefficient in a pilot operation.

    Abstract: A method includes forming a combustible mixture by mixing generally homogeneously a first fuel and air and introducing this mixture into a cylinder, compressing the combustible mixture with a piston in a compression stroke, introducing a second fuel into a prechamber at an introduction-time before start of combustion thus creating a prechamber charge, in which the second fuel being of the same or different chemical composition and/or concentration with respect to the first fuel, and spark igniting the prechamber charge. Emission of the cylinder and/or mechanical stress of the cylinder caused by the combustion are monitored. If emissions and/or mechanical stress are above respective predetermined thresholds, individually for the at least one cylinder, the chemical composition and/or the amount of second fuel introduced into the prechamber, and/or temperature of the cylinder charge and/or spark timing , are changed.

    Abstract: A method for a knock control for an internal combustion engine with at least one cylinder, which is assigned to at least one intake valve, when knocking occurs in at least one cylinder by actuation of the intake valve associated with the cylinder detected as knocking, in such a way that the temperature of the charge of the cylinder detected as knocking is reduced, the knocking in the cylinder is reduced, on actuating the intake valve associated with the cylinder detected as knocking, a cylinder-specific and/or a global measure for power compensation of the internal combustion engine is performed.

    Abstract: A method for operating a spark ignited engine, including forming a combustible mixture by mixing generally homogeneously a first fuel and air and introducing this mixture into the at least one cylinder in an intake stroke, and compressing the combustible mixture with a piston in a compression stroke thereby introducing a part of the combustible mixture into a pre-chamber. During the intake and/or the compression stroke, a second fuel is introduced into the pre-chamber at an introduction-time before start of combustion, and the second fuel is of the same or different chemical composition and/or concentration with respect to the first fuel, and a spark ignites in the prechamber. An amount of second fuel and/or the chemical composition of second fuel introduced to the pre-chamber and/or spark timing of the pre-chamber and/or an in-cylinder charge temperature is chosen such that a desired duration of combustion can be achieved.
