Abstract (en)
[origin: EP0476706A1] A skirt section of the cylinder block is shortened to the height of the rotational center (4a) of the crank shaft (4). To the bottom end of the skirt section (2b) is the lower cylinder block whose bottom (6) end is coupled to the oil pan (7). The inner space of the lower cylinder block section is divided by plural partition walls (9-12) extending transversely between the side walls of the lower cylinder block section (6). A bearing cap (20) supporting the crank shaft (4) has a boss section (20a) projecting transversely and a threaded hole is formed in the boss section. Further, the bottom end of the bearing cap (20) has a threaded hole (21) having an opening facing a side surface. The lower cylinder block section is further provided at its side wall with a hole through which the side portion of the bearing cap is connected to the side wall of the lower cylinder block section . The bottom end of the bearing cap (20) is connected to the side wall of the lower cylinder block (6) section. This arrangement for the bearing caps (20) improves rigidity for supporting the bearing caps, thereby permitting a decrease in the vibration of the engine. <IMAGE>
