Abstract: A method for operating an engine, such as a dual-fuel engine, that includes a plurality of cylinders in which an air/gas mixture of air and gaseous fuel is ignited during a power stroke using an ignition fluid that is injected into each cylinder during a power stroke of the cylinder. The air/gas mixture is injected into each cylinder, and the injection fluid is injected into the each cylinder into which the air/gas mixture has been injected. The ignition fluid is injected into the each cylinder in at least two consecutive injections during the power stroke of the each cylinder.

Abstract: A method for determining a cylinder pressure-crankshaft position association for an internal combustion engine, including metrological detection of the crankshaft angle; metrological detection of the cylinder pressure; calculation of a cylinder volume as a function of the crankshaft angle; determination of a curve for the logarithmic cylinder pressure over the logarithmic cylinder volume as a function of the crankshaft angle; analysis of the curve, and determination of an offset value for the crankshaft angle for determining a temporally exact cylinder pressure-crankshaft position association.
