The direct contact arrangement can accurately meet the sealing requirements of the side of the oil pan. During the operation of the engine, the side sealing gasket can effectively block the leakage of engine oil from the gap between the inner wall of the oil pan and the engine cylinder, and ensure that the engine oil is completely sealed in the oil pan.
[0015] As a further improvement of the above scheme, the installation hole one is concentric with the installation hole two.
[0016] Compared with the prior art, the oil pan gasket structure has the beneficial effects that:
[0017] The utility model discloses a setting arc limit board card, and the arc limit board card is connected in the inside of the limit card slot, and then the top of the top gasket is connected with the top of the oil sump body, and the rear side surface of the side face sealing gasket is connected with the inner wall of the oil sump body, and then the oil sump upper cover is positioned and installed with the positioning block, and is fixed up and down through the mounting hole no.
