Abstract
The flange interfaces of composite intake manifolds can be successfully sealed using homogeneous press-in-place gaskets, but it is essential for a smooth program launch that a team approach is used. Press-in-place gaskets provide:
-
Accommodation for the variation inherent in large composite moldings
-
Effective sealing under a broad range of conditions
-
An economical sealing system
-
The ability for the OEM to receive a manifold preassembled with gaskets
Figure 1 shows a typical arrangement of such a gasket.
The following list outlines the topics covered in this paper:
-
