焼室構造。 An intake passage that is formed in the cylinder head and introduces the air-fuel mixture into the combustion chamber, an intake valve that opens and closes the intake passage, a valve seat part that is formed at the open end of the intake passage and on which the intake valve is seated, and A combustion chamber structure of an internal combustion engine, comprising: a spark plug provided with an electrode protruding into the combustion chamber;
The valve seat portion is formed so that the side closer to the spark plug is inclined toward the upstream side of the intake passage than the opening end of the intake passage, and the inner wall of the intake passage between the valve seat portion and the opening end of the intake passage is located close to the spark plug. A recess is formed whose width gradually narrows from one side to the other side, and at the beginning of the opening of the intake valve, the side farther from the spark plug is formed in the gap between the intake valve and the valve seat than the side closer to the spark plug. A combustion chamber structure for an internal combustion engine, characterized in that the recess is formed to have a large gap, and the opening edge of the recess into the combustion chamber on the spark plug side is oriented in a direction away from the spark plug.
