摘要
A method of detecting combustion misfires in an internal-combustion engine, includes the following steps: variably actuating valve drives of the engine by an electronic engine control; performing a load-dependent control with the control system by a cylinder-control program; the load-dependent control includes the step of reducing power in at least one cylinder by separately affecting ignition and fuel supply thereto; detecting, in the control system by the cylinder-control program, the cylinder of reduced power with a cylinder-identification signal; at predeterminable intervals detecting, from signals obtained in the preceding step, resulting deviations of predetermined operating data as normal operation; detecting, as combustion misfires, deviations of the predetermined operating data from the normal operation obtained in the preceding step; and generating a setting signal upon detecting deviations in the preceding step.
