摘要： The invention relates to a two-cycle combustion engine, comprising at least one cylinder (1) accommodating a piston (2) and provided with a cylinder head, comprising a crankcase (10) which is in fluid connection with the cylinder (1) by way of transfer ports (12 to 16) which are disposed symmetrically opposite from each other with respect to a diameter plane (5) of the cylinder (1) that is determined by the axis of an outlet port (4), and comprising two injection nozzles (6, 7) for fuel disposed symmetrically to said diameter plane (5), the nozzle axes (8) of which intersect each other above the piston crown (3) in the diameter plane (5) in the bottom dead center position of the piston (2). In order to create advantageous scavenging conditions, it is proposed that the nozzle axes (8) intersect each other on the side of the cylinder axis facing away from the outlet port (4) and extend at least approximately in the outflow direction (17) of the transfer ports (12, 13) provided on the opposite side of the diameter plane (5), and that the piston (2) comprises a casing opening (21) for injection fuel into the crankcase (10) on at least one peripheral side facing the injection nozzles (6, 7).
