A method for detecting irregular combustion processes in a multicylinder diesel internal combustion engine includes detecting incorrect injections and non-injections by recording combustion noise in individual cylinders through the use of one or more structure-borne noise sensors. Subsequently, a check is performed as to whether or not sensor signals exceed threshold values individual to each cylinder within or outside fixed measurement windows.

[ We claim:] [1.] A method for detecting irregular combustion processes in a multicylinder diesel internal combustion engine, which comprises:individually recording combustion noises for each cylinder within predeterminable measurement windows through the use of at least one structure-borne noise sensor supplying structure-borne noise signals;comparing the individual structure-borne noise signals for a each cylinder with individual threshold values assigned to the cylinders;if the threshold values are exceeded, checking if the structure-borne noise signals exceed the threshold values within or outside the measurement windows; andinferring incorrect injections of injectors of an injection device when the threshold values outside the measurement windows are exceeded.
