Intake apparatus of internal-combustion engine

Abstract

Abstract PURPOSE:To strengthen the swirl force by setting the direction of the intake flow of a port which is directed to the inside of a cylinder so as to be set in the tangential direction on the concentric circle having the center of the cylinder as center, in an engine equipped with two swirl intake ports in one cylinder. CONSTITUTION:In one cylinder, two intake ports 4 and 5 are provided, and the intake port 4 is set so as to form a swirl on the circumference of a circle C having the center P of the cylinder as center. As for the intake port 5, the intake introduced into the cylinder is introduced so that a swirl is formed on the concentric circle having the center P of the cylinder as center by bending the axis line of the intake part to the cylinder of this port at the curved parts 14 and 15, for the axis line 3a of the intake introducing part of this port. Therefore, the strong swirls are formed, suppressing the collision of the both swirls.
