Patent Portfolio for License:Miniature Internal Combustion Engine Generator Patents for Sale
This innovative motor-generator consists of a miniature linear engine coupled with a linear alternator. It takes advantage of the high energy content of hydrocarbon fuels while eliminating most of the parts found in a standard internal combustion engine-generator set. The basic MICE generator design, shown in the adjacent figure, consists of a two-stroke engine, a spring, and an alternator in a linearly oscillating configuration. MICE is inherently an electric power generator, since there is no mechanical linkage with which to extract power. Pure linear motion is ensured by the use of a unique double helix or multiple helix spring. The pure linear oscillation provides sliding motion with no side forces. The piston does not use rings to seal the combustion chamber, using instead a close fit between the piston and cylinder to hold the leakage to a small enough level that essentially no cycle penalty is incurred. The small amount of leakage, in fact, provides a hydrostatic bearing force to center the piston in the cylinder. Thus, the MICE generator has low frictional losses since there are no bearing surfaces having a direct load. The low friction characteristics and absence of stress generated by direct loads allow the MICE generator to operate at very high cycle speeds, leading to high energy and power density, particularly at smaller size scales. The pure linear motion, in addition to having low frictional losses, allows operation with a solid film lubricant alone in other words, no oil with a pressure-balanced cylinder design.
Primary Application of the Technology
The company has developed the MICE generator in three power ranges. The adjacent figure shows the 5 10 W MICE generator next to the 300 500 W MICE generator which is designed to use both light (propane, butane) and heavy (JP-8, diesel) fuels. An AA battery and ruler provide a dimensional reference. Extensive testing has been performed on the 300-500 W MICE generator using both propane and JP-8 fuels. The third size range, a 100 W MICE generator, has recently developed specifically for the powered prosthesis applications. The 100 W MICE generator was designed to operate with a butane or propane fuel cartridge.
Frequently Asked Questions
Class 123: Internal-Combustion Engines
Inventions relating to prime movers or engines in which a combustible material is burned within an inc losed space or chamber and the heat energy thus developed converted into work by permitting the resulting products of combustion to act upon and through mechanical powers, the engine in question including suitable mechanism whereby the functions above enumerated are continually and automatically carried out, and such engine being designed to communicate power to some machine or device exterior to itself. This class also includes separate parts of engines coming within the above definition and also subordinate elements designed for use with such engines, and incapable of use in the manner contemplated with other devices or in other relations.Subclass 3: Generating plants
