Abstract
Abstract Precombustion ionization devices are disclosed for treating the vaporizable liquid fuel in internal combustion engines, including at least one foraminous member prepared from a catalytic metal having an oxide coating on the surface thereof. The foraminous member, or screen, is spaced from the carburetor and the engine intake of the internal combustion engine by means of a supporting gasket. The disclosed precombustion ionization devices may also be attached to a source of relatively high voltage, resulting in increased ionization of the vaporizable liquid fuel thereby, and preventing electropolishing of the metal oxide coating.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
88 words
A precombustion ionization device for interposition between the carburetor and the engine intake of an internal combustion engine employing a vaporizable liquid fuel, said device comprising at least one foraminous member including a catalytic metal thereon, and an oxide coating of said catalytic metal on its surface so as to promote reduction of said liquid fuel, and thereby improve the octane rating of said engine, and a gasket supporting said foraminous member so that said foraminous member is in spaced relationship from said carburetor and said engine intake.
Claim 2
Dependent Claim
88 words
