Abstract
A method of lining an exhaust manifold is disclosed, comprising the steps of applying a thin layer of a heat-resistant compound to the interior of an exhaust manifold and bonding the compound to the manifold. The manifold may be in two or more sections when the compound is applied and the sections may subsequently be joined together to form the manifold. The compound may contain zirconium and/or may be a ceramic material.
Claims15
A method of lining an exhaust manifold, comprising the steps of:
- (a) applying a heat-resistant compound to form a first liner on the inside of a first metal shell, the first shell comprising a first section of an exhaust manifold;
- (b) bonding the first liner to the first shell;
- (c) applying a heat-resistant compound to form a second liner on the inside of a second metal shell, the second shell comprising a second section of the exhaust manifold and being alignable with the first section;
- (d) bonding the second liner to the second shell;
- and then
- (e) joining the first and second shells together in an aligned configuration to form an exhaust manifold or a portion of an exhaust manifold.
