Abstract
Abstract A pair of closely adjacent electrically conductive coils, suitably encapsulated, are secured to or retained closely adjacent an electrical accessory and a fuel line of an internal combustion engine. When the engine is utilized to drive a rubber-tired motor vehicle a ground strap is provided to provide an electrical connection around the insulation produced by the rubber tires and the rubber motor mounts of the engine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
77 words
In combination with an internal combustion engine having a fuel line and an electrical system including means generating an electrical induction field, an engine efficiency device comprising: a pair of closely adjacent electrically conductive coils disposed on substantially parallel axes and located within said induction field, said coils comprising windings having their ends connected with each other, and means mounting said device adjacent said fuel line, said means comprising a wire member electrically insulated from said coils.
Claim 2
Dependent Claim
77 words
In combination with an internal combustion engine having a fuel line and an electrical system including means generating an electrical induction field, an engine efficiency device comprising: a pair of closely adjacent electrically conductive coils disposed on substantially parallel axes and located within said induction field, said coils comprising windings having their ends connected with each other, and means mounting said device adjacent said fuel line, said means comprising a wire member electrically insulated from said coils.
Claim 3
Dependent Claim
19 words
The combination as defined in claim 1 and in which said coils are encapsulated in a non-electrical conducting body.
Claim 4
Dependent Claim
68 words
The combination as defined in claim 1 and in which said internal combustion engine is mounted in a motor vehicle, said vehicle having rubber tires and further including a differential connected with said engine, and also a body, a gasoline tank and straps mounting said tank to said body, said invention further comprising an electrical conducting member connected between said differential and one of said gasoline tank straps.
