Abstract (en)
A pressure monitoring system for a combustion engine comprises a plurality of combustion chambers (2) and a pressure sensors (5) associated to at least some of the combustion chambers (2). A multiplexer (7) has inputs connected to at least a first one and a second one of said pressure sensors (5). A non-zero phase shift exists between the operating cycles of first and second ones of the combustion chambers (2) associated to said first and second pressure sensors (5). A controller (14) controls the multiplexer (7) to output data from the first pressure sensor (5) while the first combustion chamber (2) is in a predetermined portion of its operating cycle and pressure data from the second pressure sensor (5) while the second combustion chamber (2) is in said predetermined portion of its operating cycle.
