Engine intake manifold assembly
First Claim
1. A method for making an automotive vehicle intake manifold comprising the steps of:
- providing a first portion of an intake manifold for defining an air path, the first portion being free of at least one of a throttle body attachment, or a cylinder head flange;
joining the first portion to a throttle body assembly; and
joining the first portion to an engine cylinder head;
wherein the joining of the first portion to the throttle body assembly, the engine cylinder head or both is done with a structural adhesive having a tensile strength of at least 28 MPa; and
wherein the structural adhesive directly joins the first portion to the throttle body assembly, the engine cylinder head or both.

Abstract
An engine intake manifold assembly including a first portion configured with a first material and a second portion configured with a second material, wherein the first and second portions are adhesively bonded together. Preferably, the intake manifold assembly is additionally configured with a cylinder head flange, for mounting the same to an automotive engine component, and a throttle body attachment for attachment of a throttle body component. The cylinder head flange and throttle body attachment may be an integral component of the first or second portions or attached to the same during or after assembly of the first and second portions. Optionally, an insert is located between the assembled first and second portion to create one or more plenums thereby creating one or more air flow paths through the intake manifold assembly.

8. A method for making an intake manifold for an automotive vehicle, comprising the steps of:
-
providing a first shell portion of an intake manifold being made of a first material; and adhesively joining the first shell portion to a second shell portion of the intake manifold being made of a second material that is different from the first material, wherein the first shell portion and the second shell portion combine to form runners for air flow within the intake manifold. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 38, 39, 40, 41, 42, 47)
