く設定されていることを特徴とするエンジン。[Claims for Utility Model Registration] Intake air is introduced into the first and second cylinders via branch passages branched from the same intake passage, and the explosion in the second cylinder is caused by the explosion in the first cylinder. The time interval from the explosion of the second cylinder to the explosion of the first cylinder is
In an engine set to be smaller than the time interval until explosion of the cylinder, the time interval during which the intake and exhaust in the second cylinder overlap is less than the time interval during which the intake and exhaust in the first cylinder overlap. The engine is characterized by being set small.
