Document Type and Number:
WIPO Patent Application WO/2010/071013
Kind Code:
A1
Abstract:
An air intake manifold consisting of a resin and connected to the air intake port of a cylinder of an internal combustion engine, the air intake manifold comprising an EGR introducing opening which discharges an exhaust recirculation gas to the cylinder side, and the air intake manifold also comprising a tumble control valve, the tumble control valve being capable of being changed to an open position at which an air intake route connected to the cylinder is open and a closed position at which the air intake route is closed, the tumble control valve having a cutout section which, when the tumble control valve is at the closed position, forms a gap between the cutout section and the inner peripheral wall of the air intake route. When the tumble control valve is at the open position and at the closed position, the EGR introducing opening and the tumble control valve are not superposed on each other on a horizontal projection plane, and when the tumble control valve is at least either at the open position or at the closed position, the upstream-most position of the EGR introducing opening in the air intake direction is located within the range of the cutout section on the horizontal projection plane.
