Abstract (en)

A slave module controls fuel supply of a reference cylinder (12a) as a function of pressure detected by an acquisition chain (26). The drive shaft rotation speeds generated by the displacement of the piston (20a) of reference cylinder and the pistons (20b-20d) of other cylinders (12b-12d), are measured. A controller controls the fuel supply of other cylinders as a function of the measured speeds such that the shaft rotation speed of other cylinders follow the shaft rotation speed of reference cylinder.
