An air intake apparatus for an internal combustion engine, the air intake apparatus comprising:
- an outer port member inserted into a suction port in a cylinder head, the outer port member facing an inner surface of the suction port;
- an inner port member arranged inside the outer port member;
- an intake passage formed inside the outer port member and the inner port member, the intake passage being configured to allow an air-fuel mixture containing air and fuel supplied to a cylinder to flow therethrough;
- and
- a heater arranged inside the inner port member;
- wherein
- the inner port member is stacked on an outside of the heater in a direction orthogonal to an intake flow direction of the suction port, and is configured to insulate heat from the heater.
An air intake apparatus for an internal combustion engine, the air intake apparatus comprising:
- a port member inserted into a suction port in a cylinder head with an injector attached thereto;
- and
- an intake passage formed inside the port member, the intake passage being configured to allow an air-fuel mixture containing air and fuel supplied to a cylinder to flow therethrough;
- wherein
