燃料噴射式内燃機関における吸気装置。 An intake port is formed in the cylinder head in a downward curved shape from one side of the cylinder head toward the combustion chamber on the lower surface of the cylinder head, and a fuel injection valve for the intake port is configured to inject the fuel into the cylinder head. In a fuel injection internal combustion engine that is installed in such a position that the direction of fuel is directed toward the opening of the intake port relative to the combustion chamber, a portion of the intake port that is downstream of the fuel injection position of the fuel injection valve is provided. , a fuel injection type characterized in that a plurality of baffle plates formed in a cross-sectional airfoil shape curving along the curved intake port are arranged at appropriate intervals from the inside to the outside of the radius of curvature of the intake port. Intake system in internal combustion engines.
