Abstract: Two-cycle engine with fuel injection, of the type having at least one cylinder (3) in which a piston (5) is mounted to slide. A crankshaft is connected to this piston and housed in a housing (2), cylinder (3) further communicating with an intake circuit with pressurized combustion air (7) by at least one intake orifice (17) placed in the vicinity of the bottom dead center of the piston and with a circuit for exhaust of the combustion gases. The exhaust circuit comes out in cylinder (3) by at least two exhaust orifices: a first orifice (18) placed approximately at the level of the intake orifice (17) and a second orifice (19) placed above the first.
