摘要：
PROBLEM TO BE SOLVED: To provide a swirl formation device for an engine capable of forming effective swirl strongly and largely turning in a combustion chamber.
SOLUTION: The swirl formation device for the engine is provided with an auxiliary passage 24 leading auxiliary gas composed of air or air fuel mixture into the combustion chamber 9 from adjacent of an upstream of an intake port 70 opened and closed by an intake valve 10. A tip opening 25 of the auxiliary passage 24 is positioned at a part on an exhaust port 80 side in the intake port 70, and leads the auxiliary gas in a direction different from a normal line direction N of a cylinder inner circumference surface 3a in a view from an axial direction of the cylinder 3, and forms swirl S along the inner circumference surface 3a of the cylinder 3.
