ABSTRACT:
An oil pan structure for an internal combustion engine includes an oil pan and a baffle plate extending over a bottom of the oil pan. The oil pan is formed with at least one flow regulating barrier projecting upwards from the bottom, and extending along a longitudinal direction of the engine to separate first and second longitudinal channels. The baffle plate is formed with at least one oil collecting hole in the form of a slit extending closely along an upper end of the flow regulating barrier, at a position just behind the upper end of the barrier with respect to a rotational direction of a crankshaft. The flow regulating barrier defines a constricted venturi throat between the lower surface of the baffle plate and the upper end of the barrier, to create a fluid pressure drop as a fluid flows through the venturi throat from the first channel to the second channel. The oil collecting hole opens into the second channel by the side of the upper end of the barrier to allow the lubricating oil on the baffle plate to be sucked into the second channel by the pressure drop.
