Abstract
The cylinder block comprises an oil pan installation rail which is integral with a skirt section at a lower part of the skirt section. The installation rail is generally in the shape of a quadrangular pyramid whose width and height gradually increase in the direction from the cylinder block front end to the cylinder block rear end. The oil pan installation rail is hollow. Additionally, a transmission installation section is integral with the rear end of the oil pan installation rail and also integral with the cylinder block. In this cylinder block, engine noise reduction can be effectively achieved while attaining engine weight reduction.
