るシリンダブロツクの構造。 A water jacket is formed along the cylinder bore to a depth that does not reach into the skirt portion from the head mating surface, and a blow-by gas flow path is formed along the water jacket so as to penetrate from the head mating surface into the skirt portion. In the cylinder block, the cross-sectional area of the blow-by gas flow passage below the deepest part of the water jacket is set to be larger than the cross-sectional area of the blow-by gas flow passage from the head mating surface to the deepest part of the water jacket. The structure of the cylinder block is characterized by its large size.
