Abstract (en)

A method is disclosed for operating an engine that may have at least one cylinder with a piston reciprocally movably arranged. The method may include measuring a speed parameter of the engine. Information about a variation of the speed parameter associated with firing of the at least one cylinder may be obtained. Based on this information, an amount of fuel that may be supplied into the cylinder may be regulated so that an actual speed parameter variation value may be obtained which may be substantially equal to a desired speed parameter variation value or within a range of desired speed parameter variation values. In another aspect of the disclosure an engine may be provided that may have a sensor for sensing an engine speed parameter and that may have a controller that can perform the above method.
