Abstract
Abstract A high thermal capacity plate and means for mounting the plate in the combustion chamber of an internal combustion engine. The mounting means maintains the plate in spaced and insulated relationship from the cooled surfaces so it will maintain a higher temperature to better vaporize fuel in the chamber.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
21 words
The device of claim 1 in which the plate has sufficient mass to store heat to vaporize fuel on contact therewith.
Claim 2
Dependent Claim
20 words
The device of claim 1 in which the outer surface of the plate is non-planar to increase its surface area.
Claim 3
Dependent Claim
21 words
The device of claim 3 in which the non-planar surface has ridges to direct fuel and vapor axially in the cylinder.
Claim 4
Dependent Claim
16 words
The device of claim 1 including biasing means between the rail means and the retaining means.
Claim 5
Dependent Claim
21 words
The device of claim 5 in which the biasing means is a wedge with a spring to maintain it in place.
Claim 6
Dependent Claim
16 words
The device of claim 1 including insulation means between the rail means and the retaining means.
Claim 7
Dependent Claim
32 words
The device of claim 7 in which the insulation means comprises blocks of a hard non-compressible material having a metal sheath on at least one side to facilitate insertion along the rail.
Claim 8
Dependent Claim
48 words
The device of claim 1 in which the rail means has a triangular cross section with one side of the triangle facing toward the rail retaining means, the retaining means being a similar triangular shaped groove having a mouth slightly wider than said one side of the rail.
Claim 9
Dependent Claim
36 words
The device of claim 9 in which the cross sectional area of the triangular shaped groove is greater than the cross sectional area of the rail means with the space between them being filled with insulation.
