Abstract: The subject invention refers to an engine body for a crankcase scavenged two-stroke engine, comprising a cylinder (1) with a cylinder bore (2), and on opposite sides of the cylinder located, closed scavenging ducts (12a, 12b), as well as crankcase (10) with at least two crankcase parts, whereby the cylinder (1) and the crankcase (10) are connected to each other in a mutual parting plane (A) essentially perpendicular towards the longitudinal axis (B) of the cylinder bore (2). The engine body is characterized in that said scavenging ducts (12a, 12b) are having an essentially right-angled bend for, in said parting plane (A), running in a mutual direction around the periphery of the cylinder bore (2), whereby the scavenging ducts (12a, 12b), in level with the parting plane (A), comprise depressions (21a, 21b) in at least one of the either the cylinder (1) or the crankcase (10), as well as one connecting duct (14a, 14b) each, that connect each depression (21a, 21b) with the inner space of the crankcase (10).
