Abstract
In an engine (1), an ignition plug (22) is arranged between a first intake port (6) and a second intake port (7). In a case where a downstream end portion (71) of the second intake port (7) is divided into a first intake port (6) side and an opposite first intake port (6) side, an inner wall surface (71a) of an opposite first intake port (6) side portion extends in a direction toward the first intake port (6) as extending from an upstream side to a downstream side of the second intake port (7).
