Abstract
The present invention relates to a method of injecting fuel into the combustion chamber (16) of a cylinder of a direct-injection four-stroke internal-combustion engine, notably of diesel type, that can run according to a homogeneous combustion mode and according to a conventional combustion mode. According to the invention, this method consists, for the conventional combustion mode of the engine, in feeding into this chamber a first amount of fuel in the vicinity of the top dead centre of the piston at the beginning of the intake phase and another quantity of fuel in the vicinity of the top dead centre of this piston at the end of the compression phase.
