Sealing device for an oil pan adapter in an internal combustion engine

摘要

An oil pan adapter in the form of a rectangular frame with transverse reinforcing ribs is mounted to the underside of a cylinder block both for the higher adaptability for the installation of various type oil pans and for noise reduction through the damping of cylinder block vibration. One of the opposite end faces of the oil pan adapter is held against a flywheel housing mounted to one end of the cylinder block. For fluid tightly sealing this end face of the oil pan adapter, there is formed therein a generally U shaped groove including a pair of vertical limbs each having a horizontal limb joined to its top end. Each horizontal limb is open not only toward the flywheel housing but also toward the cylinder block. A sealing strip of matching shape and size is engaged in this U shaped groove to be held against both the flywheel housing and the cylinder block.
