    Publication number: 20190040789
    Abstract: A variable-compression ratio direct-injection internal-combustion engine comprising at least a cylinder (10), a cylinder head (12) carrying a fuel injection means (14) spraying fuel in a single sheet (34) of fuel jets (36), a piston (16) sliding in this cylinder, and a combustion chamber (32) delimited on one side by upper face (42) of the piston comprising a projection (46) rising up towards the cylinder head and arranged in the cent of a concave bowl (44). According to the invention, the combustion chamber comprises at least two mixing zones (Z1, Z2) into which fuel jets (36) are injected, one (Z1) of the zones being used for a maximum compression ratio (Tmax) and the other (Z2) zone being used for a minimum compression ratio (Tmini).
