Two-stroke-cycle internal combustion engine using pneumatically assisted direct fuel injection

A two-stroke-cycle internal combustion engine using pneumatically assisted direct fuel injection comprising a cylindrical body (11) within which is foreseen a first driving cylinder 13 which contains a first piston (12) and a second compressor cylinder (21), which contains a second piston (20), both pistons (12, 20) being connected through connection rods (16, 17) to a driving shaft (14), in a head of the cylindrical body (11) being foreseen a feed channel (43), into which a fuel electroinjector (44) opens, which connects with an automatic valve (28) to a combustion chamber (60) at the end of the first cylinder (13), an engine crankcase (26) and a compressor crankcase (25) containing the connection rods (16, 17) and being connected through apertures (27), the second compressor cylinder (21) being connected to the compressor crankcase (25) through countersunk channels (42).
