摘要 |
<p>PCT No. PCT/DE96/01609 Sec. 371 Date Jun. 11, 1997 Sec. 102(e) Date Jun. 11, 1997 PCT Filed Aug. 30, 1996 PCT Pub. No. WO97/11345 PCT Pub. Date Mar. 27, 1997A method is introduced for detecting combustion misfires on the basis of the time-dependent course of the rotational movement of a transducer wheel, which is coupled to the crankshaft of an internal combustion engine. In this method, the segment times, in which predetermined segments of the transducer wheel pass a sensor, are detected and processed to a measure for the rough running of the internal combustion engine. A conclusion as to misfires is drawn from the behavior of the measure. The measure for the rough running is formed by digital filtering of segment times with predetermined filter coefficients.</p> |
