Claims

[Scope of utility model registration request]

Each cylinder is equipped with three intake ports that branch from the intake passage and open on one side of the combustion chamber through intake valves, with the central intake port being the center of the opening, and the center of the opening being the intake ports on both sides. In an engine intake passage structure in which the engine intake passage is located at a location farther from the center of the bore than the line connecting the opening centers of the cylinder, each of the intake ports on both sides is located outwardly away from the center intake port when viewed from above the cylinder bore. The central intake port is offset away from the center of the cylinder bore with respect to each intake port on both sides, and These 3 ports are connected to the port.
An engine intake passage structure characterized by being provided with a partition port wall that partitions two intake ports from each other.
