Abstract
Abstract Apparatus for improving fuel utilization efficiency of an internal combustion engine comprises an elongate device for mounting in a liquid fuel line having a plurality of radially spaced longitudinal bores in a solid plastic housing communicating with an inlet and outlet. Aligned magnets are retained in shallow axial cavities at each end of the housing. The device is energized by placement between a pair of electrodes having a high voltage for several hours.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
In a vehicle powered by an internal combustion engine having a liquid hydrocarbon fuel reservoir and a fuel inlet line extending between the engine and the fuel source, the improvement therein which comprises fuel treatment apparatus mounted in the fuel inlet line comprising an elongate plastic housing having a plurality of eccentric lengthwise bores therethrough oriented at 90° radial spacing around a longitudinal housing axis, a shallow axial cavity adjacent each end of the housing, and a cylindrical magnet contained in each cavity, said magnets having poles aligned with the North poles thereof directed toward the outlet end of the housing.

Claim 3
Dependent Claim
59 words
The apparatus of claim 1 also comprising a fluid inlet at one end of the housing, a fluid outlet at an opposite end thereof, a fluid inlet chamber interior of the housing communicating with the fluid inlet and the lengthwise bores, and a fluid outlet chamber interior of the housing communicating with the fluid outlet and the lengthwise bores.
Claim 4
Dependent Claim
13 words
