Abstract
A method for ascertaining whether a combustion process is being carried out in a cylinder of an internal combustion engine, it being decided whether or not the combustion process is present as a function of a relative angle between a characteristic signature of a variable characterizing a time curve of a state variable of the internal combustion engine and a specifiable crankshaft angle.

A method for ascertaining whether a combustion process is being carried out in a cylinder of an internal combustion engine, the method comprising:
- deciding whether the combustion process is present as a function of a relative angle between a characteristic signature of a variable characterizing a time curve of an energy of the internal combustion engine and a specifiable crankshaft angle;
- wherein the energy includes a kinetic energy given by the rotational movement of the internal combustion engine.
A method for operating an internal combustion engine, the method comprising:
- ascertaining whether a combustion process is being carried out in a cylinder of an internal combustion engine, by performing the following:
- deciding whether the combustion process is present as a function of a relative angle between a characteristic signature of a variable characterizing a time curve of an energy of the internal combustion engine and a specifiable crankshaft angle;
- wherein the energy includes a kinetic energy given by the rotational movement of the internal combustion engine;
- and
- controlling the internal combustion engine as a function of the result of the ascertaining.
A non-transiory computer readable medium having a computer program, which is executable by a processor, comprising:
- a program code arrangement having program code for ascertaining whether a combustion process is being carried out in a cylinder of an internal combustion engine, by performing the following:
- deciding whether the combustion process is present as a function of a relative angle between a characteristic signature of a variable characterizing a time curve of an energy of the internal combustion engine and a specifiable crankshaft angle;
- wherein the energy includes a kinetic energy given by the rotational movement of the internal combustion engine.
A control and/or regulating device, comprising:
- a controller device configured for ascertaining whether a combustion process is being carried out in a cylinder of an internal combustion engine, by performing the following:
- deciding whether the combustion process is present as a function of a relative angle between a characteristic signature of a variable characterizing a time curve of an energy of the internal combustion engine and a specifiable crankshaft angle;
- wherein the energy includes a kinetic energy given by the rotational movement of the internal combustion engine.
