<p>A method for detection of misfiring of an internal combustion engine (1), wherein the torque of the internal combustion engine is measured with the aid of a torque sensor (2) mounted on the crankshaft (3) of the internal combustion engine and wherein a torque signal is sampled speed-synchronously with the aid of a sensor (4). A digital filtering of the torque signal is carried out with a digital filter (5) with a finite impulse response which blocks or damps a selection of integer or half-integer multiples of the speed of the internal combustion engine, where the selection of speed multiples is substantially dependent on the number of cylinders of the internal combustion engine.</p> |
