description	A method to determine the injection pattern in the compression stroke (COMP) of the combustion cycle of the cylinders (2) of a direct-injection internal combustion engine (1), comprising the steps of determining the initial quantity (QFinit_comp ) of fuel and an objective quantity (QFobj_comp ) of fuel to be injected for each partial injection of a maximum number (Nmax_comp ) of partial injections; determining an effective quantity (QFeff_comp ) of fuel to be injected for each partial injection as a function of the respective initial quantity (QFinit_comp ) of fuel and of the respective objective quantity (QFobj_comp ) of fuel; and determining an objective pattern of partial injections to be performed in the compression stroke (COMP) as a function of the value of the end of injection angle (EOI) and of the effective quantity (QFeff_comp ) of fuel to be injected for each partial injection of said maximum number (Nmax_comp ) of partial injections to be performed in the compression stroke (COMP).
