METHOD TO DETECT AND CONTROL DETONATION PHENOMENA IN AN INTERNAL COMBUSTION ENGINE

摘要

Method to detect and control detonation phenomena in an internal combustion engine (1) provided with a number of cylinders (2) and with at least two detonation sensors (18); for each combustion cycle as a function of the cylinder (2) and of the engine point that is being explored, the method comprises processing the signal (S*, S**) coming from each detonation sensor (18) so as to determine a detonation energy (S el *, S el **) for each detonation sensor (18); calculating a detonation index (I*, I**) for each detonation sensor (18) and controlling the internal combustion engine (1) as a function of a total detonation index (I det ) through the algebraic sum of the detonation indexes (I*, I**) for each detonation sensor (18).
