ンジンの冷却水通路構造。 A cooling water passage structure for a V-type engine in which two banks are arranged offset in the crank width direction, a water introduction hole is provided at one end between the banks, and cooling water is distributed and supplied to each bank from the water introduction hole. a first distribution passageway extending from the water introduction hole toward a first bank closer to the water introduction hole; and a second bank farther from the turning part of the first distribution passageway to the water introduction hole. a second distribution passage extending toward the first distribution passage;
The distribution passage and the second distribution passage communicate with each other through a communication hole formed by drilling a hole from the water introduction hole side, and the inner wall of the communication hole on the second bank side has a communication hole formed from the water introduction hole through the communication hole. A cooling water passage structure for a V-type engine, characterized in that a weir is formed to guide cooling water flowing toward a second distribution passage side so as to be distributed to a first distribution passage side.
