Abstract (en)
[origin: WO2019244075A1] A spark ignition engine (1) is described, comprising a cylinder (10) having a cylinder central axis (X1), a cylinder head (11) and a piston (20) movable along the cylinder central axis (X1), wherein a combustion chamber (30) is adapted to be defined between the cylinder head (11) and the piston (20), said engine (1) comprising a PFI (Port Fuel Injection) injector (40) arranged to inject a fuel (41) in PFI mode and at least one gas Dl (direct injection) opening (51) arranged to inject gas (52) in Dl mode, wherein the at least one gas Dl opening (51) is configured to inject the gas (52) into the radial periphery (F1) of the combustion chamber (30). Moreover, a fueling method of said spark ignition engine (1) is described.
