Heat blocker

Abstract

The present invention 10 discloses a high temperature insulation blanket for an exhaust system of an internal combustion engine. The blanket 10 can be selectively manufactured to encompass any engine parts deemed desirable by the user. All sides of the insulative blanket 10 have a high temperature abrasive resistant outer shell material 24 fixedly attached thereto. The high temperature insulative blanket is comprised of a ceramic core 22 having an interior engine engaging layer and an exterior atmospheric air layer. The interior layer is comprised of an inconel or monel mesh material 20 that provides a spacing between the engine components and the ceramic fill 22. An inconel or monel liner 32 prevents any engine fluids from wicking into the ceramic fill 22. The exterior layer 24 is comprised of a Teflon layer that is substantially impervious to petroleum based products and solvents. The present invention 10 provides three means of closure for the insulative blanket. The first 26 being a spring closure provides means for quick installation and/or removal of the insulative blanket. The second means of closure is comprised of industrial grade hook and loop material 34 fixedly attached to the edges of the insulative blanket with each edge having the mating member of the hook and loop material. This method of closure also provides a quick and easy means for installing the insulative blanket. The third method of closure involves hooks 38 being provided on one edge of the insulative blanket and eyelets 40 provided along the opposed edge of the insulative blanket wherethrough a wire-like thread 36 can be laced and engaged around the hook elements.
