A cylinder-crankcase for a multi-cylinder internal combustion engine with a V-arrangement of the cylinders, which consists of welded-together cast housing elements that are connected in series in a building-block-like manner; each of the housing elements includes a cross wall with a bearing socket-half for a crankshaft bearing and two cylinder shells for each cylinder row, whereby the two cylinder rows are mutually offset by the width of a connecting rod bearing and the separating planes of the housing elements do not pass through the cylinder centers; the cross wall thereby includes an upper boundary which is substantially rectilinear but inclined with respect to the center cross plane of the housing element, as viewed in plan view, while imaginary lines starting from this boundary and extending in the neutral center surface of the cross wall in the direction toward the area of the bearing socket are substantially straight lines.
