る内燃機関。 In addition to placing the spark plug approximately in the center of the combustion chamber,
Multiple intake valves are placed in positions that do not interfere with this,
In an internal combustion engine in which a plurality of injection ports are formed in a fuel injection valve provided at a confluence of intake ports communicating with each intake valve, at least one of the intake valves has an intake air flow directed in a direction away from the center of the combustion chamber. An internal combustion engine characterized in that the valve diameter of the valve is set smaller than other intake valves, and the injection port of the fuel injection valve is formed so that more fuel is injected toward the small-diameter intake valve than the other intake valves.
