A crankcase of an internal combustion engine with at least one main lubricant channel for supplying the internal combustion engine with lubricant and with at least one oil return flow channel () for return guidance of the excess lubricant into a reservoir container (), wherein the oil return flow channel () exhibits a peg-shaped widening (), which is formed by the attachment a bearing support of an oil channel core (). The invention further concerns an oil channel core.

In an internal combustion engine including a cylinder head and at least one camshaft and accessory units comprising pumps mounted on the front end of the engine on which also drive means for the camshaft of camshafts are disposed, the accessory units are operatively coupled to the drive means for the camshafts or camshafts so as to be driven thereby.

Internal combustion engine

A cylinder head cover for a direct-injecting internal-combustion engine has an injection nozzle holder arranged in the cylinder head between charge cycle valves and a clamping shoe for fixing the position of the injection nozzle holder in a receiving bore in the cylinder head. The cylinder head cover is constructed to be pulled in in the area of the injection nozzle holder and has a passage for the injection nozzle holder. The pulled-in cylinder head cover in the area of the injection nozzle holder is pulled down to the cylinder head. Starting from that area, a drainage-groove-type indentation leads to the inlet side of the internal-combustion engine.
