Abstract
A cylinder block () includes an inlet portion (), a narrow portion (), and an inclined portion (). A cylinder head includes a head-side discharge portion. The inlet portion is formed on the first cylinder side of a cylinder array, and introduces coolant to a block-side water jacket (). The narrow portion is formed in the vicinity of the inlet portion, and restricts the coolant introduced through the inlet portion from flowing to an intake-side channel () of the block-side water jacket. The inclined portion is formed in the vicinity of the inlet portion, and guides the coolant introduced through the inlet portion toward the head. The head-side discharge portion is formed on the fourth cylinder side of the cylinder array, and discharges the coolant from a head-side water jacket. A communication path for communicating between the water jackets is formed on the head side of the inclined portion.
