Abstract:
A fuel injection control method intended for a direct-injection internal-combustion engine comprising at least an injector (20) of fuel jet nappe angle (a1), a cylinder (10), a cylinder head (12), a piston (18) sliding in this cylinder and connected to a crankshaft, and a combustion chamber delimited by wall (26) of the cylinder, cylinder head (12) and upper face (24) of piston (18), characterised in that it consists in:determining a lower limit position (PL) of piston (18) below which wall (26) of the cylinder is likely to be wetted by the fuel jets from the injector, determining the effective position of this piston, locating this effective position of the piston in relation to the lower limit position, adjusting the fuel injection parameters according to the effective position of the piston in relation to the lower limit position.
