PROBLEM TO BE SOLVED: To quickly consume lubrication system return fuel which may possibly become contaminated as it is supplied to an engine lubrication system, and reduce and eliminate choking in an injection hole in an injection system, and increase of slide friction in an engine lubrication system. SOLUTION: An inner part of an oil pan 3 provided on an engine 1 is parted to a first chamber 8 and a second chamber 9 by an oil pan separator 7. In the second chamber 9, a discharge port 4a for a fuel supply passage 4 from a fuel tank 2, and an intake port 13a to a lubrication system fuel supply passage 13 to supply fuel to the engine lubrication system 12. In the first chamber 8, a discharge port 16a for a lubrication system fuel return passage 16 to return lubrication system return fuel, and an intake port 18a for an injection system fuel supply passage 18 to supply fuel to the injection system 17 are disposed.
