Summary: | To provide an oil pan to be used for a horizontal front exhaust type internal combustion engine mounted on a vehicle body, for improving the rigidity of a power plant including the oil pan even when forming a hollow part into which an exhaust pipe passes.SOLUTION: With the hollow part formed, a bottom 9 of an oil pan 1 includes a shallow bottom part 9a located at a site of the hollow part, and a deep bottom part 9b located in front thereof. On each of right and left side walls 3, a step-shaped reinforcement part 24 is formed at a position somewhat higher than the shallow bottom part 9a while extending over the whole length. Thus, rigidity against vertical bending and torsion is improved. As a result, the rigidity of the power plant is also improved.SELECTED DRAWING: Figure 6
【課題】横置き前排気方式で車体に搭載される内燃機関に使用するオイルパンにおいて、排気管を通すために抉り部を形成した場合であっても、オイルパンを含むパワープラントの剛性を向上させる。【解決手段】抉り部を形成したことにより、オイルパン1の底部9は、抉り部の箇所に位置した浅底部9aと、その手前に位置した深底部9bとが構成されている。左右の側壁3に、浅底部9aよりもやや高い位置において全長に延びる段状補強部24を形成している。これにより、上下方向の曲げや捩じりなどに対する剛性が向上する。その結果、パワープラントの剛性も向上できる。【選択図】図6 |
