Abstract
There is provided a V-type engine, in which deck cylinder parts of a cylinder block are offset in the same direction as a rotational direction of a crankshaft, and oil separation chambers are provided at an upper portion of the cylinder head displaced to a lower side by the offset. Therefore, an allowance in the axial direction of cylinders may be provided above a cylinder head of the deck cylinder parts on the lower side, and the capacity of the oil separation chambers is increased by the allowance so that the oil separation performance may be improved, while an increase in the total width and total height of an engine block is suppressed.
