Abstract (en)
The structure has a crankshaft supported on a crankcase for rotation about an axial center extending in a horizontal direction, and an oil pan fixed to the crankcase lower end. The pan has vertical walls (26-28) protruding from outer edges of a bottom plate (25) and fixed to the crankcase, where the plate and walls are formed by casting. The plate is formed so that its spherical surface has a center at a point above the pan.
An engine 1 comprises a crankcase 2, a crankshaft 3 supported on the crankcase 2 for rotation about an axial center 4 extending approximately in the horizontal direction, and an oil pan 9 fixed to the lower end of the crankcase 2. The oil pan 9 comprises a bottom plate 25, and vertical walls 26-29 protruded upwardly from outer edges of the bottom plate 25 and fixed to the crankcase 2 at the protruded ends. The bottom plate 25 and the vertical walls 26-29 are formed integrally with one another by casting. The bottom plate 25, as viewed as a whole, is formed approximately in agreement in shape with part of a spherical surface 34 with a center 33 at a point above the oil pan 9. Such an arrangement can prevent vibration in portions of an oil pan during engine operation for the prevention of generation of noise from the oil pan and to achieve with simple structure and without increasing the weight of the oil pan.
