Definitions
- the present invention relates to an oil pan structure that is provided under an engine block and stores engine oil.
- engine oil has been used for engine lubrication and cooling.
- This engine oil is stored in an oil pan provided in the lower part of the engine, and circulates in each part of the engine by an oil pump.
- Engine oil that circulates in each part of the engine drips into the oil pan below.
- the engine oil dripped into the oil pan is circulated through the engine parts again by the oil pump. During this time, engine oil receives heat from each part of the engine and cools each part.
- engine oil forms an oil film in each part of the engine to promote lubrication between parts and prevent parts from being oxidized.
- the engine oil stored in the oil pan is also cold, and the viscosity is high, so that it is not suitable for circulating each part of the engine and lubricating each part. Therefore, immediately after the cold start, it is desirable to raise the temperature of the engine oil as soon as possible so that it has an appropriate viscosity.
- the oil pan is divided into a plurality of compartments, and immediately after cold start, engine oil in one compartment is easily circulated, and the engine oil in this compartment is warmed earlier and is in a desirable state. Has already been studied (see Patent Document 1).
- Patent Document 2 An oil pan structure as disclosed in Patent Document 2 has also been proposed.
- a main chamber where the engine oil suction port is arranged and a sub chamber where the suction port is not arranged are arranged.
- An oil pan separator for partitioning is provided in the oil pan, and a communication hole that connects the main and sub chambers is adopted. Such a communication hole controls the conduction of the engine oil between the sub chamber and the main chamber by utilizing the change in the viscosity of the engine oil.
- the main room is sometimes called “Room 1”.
- the sub-room is sometimes called “second room”.
- Oil pan separators are sometimes called “sub oil pans”. Oil pans are sometimes called “main oil pans”.

- the lower structure of the engine block in which the upper body is integrally formed may be the lower end of the engine block itself. Also, it may be a separate body from the engine block and interposed between the engine block and the main oil pan. In this case, the lower structure separate from the engine block can function as an oil pan together with the main oil pan by assembling the main oil pan.
- the upper body of the sub oil pan may be configured to include a first communication portion and a second communication portion that communicate with the first chamber and the second chamber, respectively, and have different installation heights.
- a sub oil van disposed inside the main oil pan and forming the first chamber and the second chamber inside the main oil pan is an upper body formed integrally with the lower structure of the engine block. And the lower body to be mounted on the upper body, the sub oil pan can be mounted with high accuracy with respect to the prescribed oil level in the oil pan.
