Abstract (en)
[origin: WO2006087451A1] The invention relates to a method for control of fuel injection for an internal combustion engine, in particular with direct fuel injection, comprising at least one cylinder (10), one piston (30) running in said cylinder, with a projection (34) arranged in a concave bowl (32), a fuel injector (22) and a combustion chamber (26). According to the invention, during high engine loads, a first amount of fuel is injected at a piston (30) position of between 35 and 70 ° before the top dead centre position of said piston, followed by an injection of at least one second amount of fuel, the first amount of fuel being less than the second amount and the fuel is injected into said combustion chamber by means of an injector (22) with a cone angle (a<SUB>1</SUB>) less than or equal to 2Arctg CD/2F where CD is the diameter of the cylinder (10) and F the distance between the points of origin of the fuel jets from the injector (22) and the position of the piston corresponding to a crankshaft angle of 50 ° with relation to the top dead centre (PMH) of the piston.
