US 12,247,536 B2 · Engine intake manifold

Abstract

An intake manifold includes a body member defining an interior chamber having an upper surface and a perimeter wall depending therefrom and extending to a perimeter edge, which extends in a plane. An air intake port extends through the body member and opens into the interior chamber. An EGR tube extends through an EGR tube port in the body member and the EGR tube opens into the interior chamber. A MAP sensor extends through a MAP port in the body member such that an interior portion of the MAP sensor is positioned in the interior chamber and extends from an interior surface of the body member upper surface by a first distance. A shield member includes a shield wall that depends from the interior surface of the upper surface by a distance larger than the first distance and defines a shielded area about the interior portion of the MAP sensor.
