Abstract: Method for detecting abnormal combustion, in particular combustion knock or pre-ignition, in at least one cylinder of an internal combustion engine, comprising a step (S3) of determining cylinder specific measurement data for each one of the at least one cylinder based on measurement signals acquired by at least one vibration sensor; a step (S6) of obtaining a cylinder specific detection configuration for each one of the at least one cylinder; and a step (S7) of analyzing, for each one of the at least one cylinder, the cylinder specific measurement data based on the associated detection configuration to detect an abnormal combustion condition.

Abstract: A pressure detection device (10) comprises a pressure detection element (21) which receives pressure so as to output a detection signal corresponding to the pressure and a processing circuit (30) which processes and outputs the detection signal output from the pressure detection element. A processing circuit (30) is adopted which includes at least one or more amplifier circuits which amplify an output signal (Vout21) from an integrator circuit and a base voltage adjustment circuit (40) which is connected between a supply portion of a reference voltage (Vr) fed to the amplifier circuit and an input terminal of at least one of the amplifier circuits and which adjusts the magnitude of a base voltage (Vb22) that is a potential when a detection signal (Qi) in an output signal (Vout22) output from the amplifier circuit is not present.
