Abstract
The present invention relates to a fuel injection method for a compression-ignition direct-injection internal-combustion engine comprising at least a cylinder (), a cylinder head () carrying fuel injectors (), a piston () sliding in the cylinder, a combustion chamber () delimited on one side by an upper face () of the piston comprising a projection () extending in the direction of the cylinder head and located in the center of a concave bowl () with at least two mixing zones (Z, Z). The injectors project fuel in at least two fuel jet sheets () with different sheet angles (A, A). The injection into the combustion chamber with the fuel jets () by one sheet () is in a radial direction (C) which forms a non-zero angle (b) with the radial direction (C) of fuel jets () of the other sheet (). The oxidizer is admitted into the cylinder in a swirling motion with a swirl number less than or equal to 1.5.
