INTAKE MANIFOLD AND METHOD OF MAKING THE SAME

摘要

INTAKE MANIFOLD AND METHOD OF MAKING THE SAME An intake manifold wherein separately produced sections of metallic or plastic material have neighboring surfaces defining a chamber which surround the cavity of the manifold and is filled with a vulcanized elastomeric material which is bonded to the neighboring surfaces by a coupling agent, such as silane. The elastomeric material can be silicon rubber, nitryl rubber or polyacrylate rubber. The neighboring surfaces of the sections can form a tongue-and-groove connection which surrounds the cavity of the manifold and is surrounded by the elastomeric material.
