Abstract
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 (10) for return guidance of the excess lubricant into a reservoir container (11), wherein the oil return flow channel (10) exhibits a peg-shaped widening (12), which is formed by the attachment a bearing support of an oil channel core (18). An oil channel core as well as a process for producing a crankcase.
Claims16
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 lubricant return flow channel (10) for return flow of the excess lubricant to a reservoir (11), thereby characterized, that the oil return channel (10) includes a peg-shaped widening (12), which is constituted by a bearing support of an oil channel core (8).
An oil channel core according to claim 6, wherein the peg-shaped widening (12) is oriented transverse to the main direction of elongation of the oil channel core (18).
An oil channel core according to claim 6, wherein the peg-shaped widening (12) is attached or unitary.
An oil 04 channel core according to claim 6, wherein the peg-shaped widening (12) is provided as bearing support for thermal treatment.
A process for producing a crankcase of an internal combustion engine, with at least one main oil channel for supplying the internal combustion engine with lubricant and with at least one oil return channel (10) for return flow of excess lubricant to a reservoir (11), wherein the oil return channel (10) is formed in a cast part by a removable oil channel core (18), thereby characterized, that the oil channel core (18) for the oil return flow channel (10) includes a peg-shaped widening (12).
