In a V-type engine, the cylinders in one of the cylinder banks are connected to a first communicating passage and the cylinders in the other cylinder bank are connected to a second communicating passage. The cylinders in each cylinder bank do not fire one after another. First and second intake air supply passages are connected to the first and second communicating passages at positions near one end of the communicating passages and extend toward the respective other ends of the communicating passages just above the communicating passages.
