Abstract

A method for determining cylinder-specific combustion features of an internal combustion engine, the cylinder-specific combustion features being ascertained from a variable which represents the crankshaft speed, especially being ascertained from a signal of a crankshaft sensor or camshaft sensor. The cylinder-specific combustion features include a combustion position of at least one cylinder and/or a torque of the crankshaft.
