Abstract (en)
[origin: WO2018060339A1] The invention relates to a method for producing an output data stream (15) with at least partial interference suppression by detecting and selectively filtering a combustion chamber signal (1) which is picked up at an internal combustion engine, comprising the following steps: - picking up a combustion chamber signal (1) and producing combustion chamber signal data stream (2), - simultaneously picking up a crankshaft angle (3) and producing a crankshaft signal data stream (4), - splitting or duplicating the combustion chamber signal data stream (2),- producing a first filtered combustion chamber signal data stream (23), - if appropriate producing a second filtered combustion chamber signal data stream (24), - producing a first transformed combustion chamber signal data stream (20) by transforming (8) the first filtered combustion chamber signal data stream (20) from a time basis to a crankshaft angle basis and producing a second transformed combustion chamber signal data stream (21) by transforming (9) the second, if appropriate filtered, combustion chamber signal data stream (24) from a time basis to a crankshaft angle basis, - combining the transformed combustion chamber signal data streams (20, 21) so that the output data stream comprises the first transformed combustion chamber signal data stream (20) in a first crankshaft angle range (17) and the second transformed combustion chamber signal data stream (21) in a second crankshaft angle range (19).
