  • Intake passage structure for an engine
    Patent number: 10753309
    Abstract: An intake passage structure for an engine includes an intake port in a cylinder head of the engine, and connected to a combustion chamber to define an intake passage. The intake passage structure further includes a heat insulating member disposed along an inner surface of the intake port, and including a bulge having an upstream end surface which is a portion of an upstream end surface of the heat insulating member, the bulge has a radially outwardly protruding radially outer surface and has an increased wall thickness. The wall thickness of the bulge increases from downstream to upstream of the intake port. The upstream end surface of the bulge includes an injection machine connecting portion facing an injection gate configured to inject resin for forming the heat insulating member into the intake port.
