Method for correction of the spark advance for an internal combustion engine with a continuous phase transformer at the intake and/or exhaust

Method for correction of the spark advance for an internal combustion engine (1) with a continuous phase transformer at the intake and/or exhaust; for each cylinder (2), the method consists of calculating a theoretical value (AAth) of the optimum spark advance according to the drive point, calculating a first correction value (AAC1), which depends on the mass (%EGR) of burnt gas trapped in the cylinder (2) at the end of the intake phase, calculating a second correction value (AAC2), which depends on the torque value (CMI) generated, and calculating the actual value (AAeff) of the spark advance, by adding the two correction values (AAC1, AAC2) to the theoretical value (AAth) of the spark advance.
