| 摘要 |
The invention relates to an internal-combustion engine having a cylinder block and crankcase and a case structure which preferably has two cylinders or cylinder bank rows (2, 3) arranged in a V-shape with respect to one another, an endless drive extending on the face of the cylinders or cylinder bank rows, which drive comprises a timing chain, for connecting a crankshaft with camshafts (9 to 12) arranged in the cylinder heads, the timing drive chain (14) being covered by a timing drive cover (18). It is suggested that the timing drive cover (18) or the case structure situated opposite the timing drive cover has a ribbing (32, 34, 36) by way of which a targeted separation and/or return takes place of the oil carried along by the timing chain (14) in the direction of the cylinder heads (7, 8). As a result, among others, the venting of the crankcase is not hindered which takes place by way of the timing chain case.
