A combustion chamber is formed, and a squish zone is formed between a portion of the inner wall surface of the head other than the recess and the upper surface of the piston, and one exhaust port and a first intake port are opened and closed by an exhaust valve. The first intake ports, which are opened and closed by valves, are opened in the recess so as to be adjacent to each other in the cylinder circumferential direction, and the second intake ports, which are opened and closed by the second intake valve, are opened in a part other than the recess in the inner wall surface of the head. one intake passage opened in the cylinder head and communicated with the first intake port and the second intake port, and the intake passage allows intake from the second intake port to flow into the combustion chamber. is oriented so as to sweep the first intake port and then sweep the exhaust port, and a communicating portion from the second intake port to the first intake port is substantially along the circumferential direction of the cylinder. The combustion chamber structure of the engine is characterized by:
