Abstract

The present invention relates to a method for controlling the injection of a fuel into a direct-injection internal combustion engine, particularly a diesel engine, comprising a cylinder (10) having a chamber (14) for the combustion of a fuel/air mixture and including a means (20) for injecting fuel into said chamber in at least one jet (24) including a main jet portion (26) and at least one secondary jet portion (28) following the main portion. According to the invention, the method involves injecting the main jet portion (26) into the combustion chamber in at least one direction (A, B, E), and injecting the secondary jet portion (28) in at least one direction (C, D, F, G, H, I, J, L, M) forming a nonzero angle (α, Θ) with the direction of said main jet portion.
