摘要： In a port-controlled two-stroke internal combustion engine with an engine block comprising a crankcase and a cylinder block including pistons connected to a crankshaft by crosshead rods with crossheads guided for linear movement with the pistons, and connecting rods extending between the crossheads and the crankshaft a partition structure is arranged between the crankcase and the cylinder block and includes hollow cylindrical sleeves which project axially into the cylinders to a point closely adjacent the undersides of the piston tops when the pistons are in their bottom dead center positions and the sleeves are spaced from the cylinder walls to form between the sleeves and the cylinder walls annular spaces for receiving the depending skirts of the pistons.
