Abstract
A method of monitoring proper operation of an internal combustion engine by analyzing an engine speed includes the following steps: determination of an acceleration characteristic for each cylinder, which is a function of the engine acceleration between preferably directly successive working cycles of a specifiable number of examined cylinders; selection of the acceleration characteristics of one or a plurality of cylinders on the basis of specifiable criteria; and modification of an error characteristic provided for each examined cylinder as a function of the acceleration characteristic assigned to the cylinder, if an acceleration characteristic assigned to the cylinder has been selected.
