Method for injecting fuel

Abstract

Abstract The invention relates to a method for injecting fuel into the combustion chambers of an internal combustion engine comprising a plurality of cylinders, especially a direct-injection internal combustion engine. According to said method, a main injection and a variable number of secondary injections associated with the main injection are carried out during a working cycle of a piston performing an oscillating movement in a cylinder. If the number of secondary injections carried out per associated main injection is modified, the modified number of secondary injections is carried out only in part of the cylinder, while the original number of secondary injections is carried out in the other part of the cylinder. The modified number of secondary injections is first carried out for a small part of the cylinder and then for a larger part of the cylinder.
