STRUCTURE OF OIL PAN AND OIL-PAN SEPARATOR

摘要

PROBLEM TO BE SOLVED: To provide a structure of an oil pan effectively raising temperature of engine oil. SOLUTION: In the structure of the oil pan, an oil-pan separator 3 is placed in the oil pan 2 to partition the oil pan into a main chamber having an inlet port and a secondary chamber having no inlet port. The oil-pan separator 3 has a recess for forming the main chamber. The main chamber communicates with the inside of an engine block 1. The recess has communication holes 3c, 3d for allowing the main chamber to communicate with the inside of the engine block 1. The secondary chamber is formed around the whole periphery of the main chamber, the outer surface of the bottom of the oil-pan separator 3 is not in contact with the inside of the bottom of the oil pan 2.
