US Patent:

20080042540, Feb 21, 2008

Filed:

Aug 16, 2006

Appl. No.:

11/464924

Inventors:

James Rhett Mayor - Ypsilanti MI, US
Werner J. A. Dahm - Ann Arbor MI, US

Assignee:

The Regents of the University of Michigan - Ann Arbor MI

International Classification:

H01T 13/20

US Classification:

313141, 313143

Abstract:

The micro-ignitor of the preferred embodiment includes a first electrode having a body shaped as an elongated tube and a tip that extends from the body; a second electrode having a body located substantially within and extending at least a length of the body of the first electrode and a tip that extends toward and is spaced from the tip of the first electrode; and an electrical insulator to electrically insulate between the body of the first electrode and the body of the second electrode. The first electrode and the second electrode cooperate to carry an electrical charge and to produce an ignition spark between the tip of the first electrode and the tip of the second electrode. Although the micro-ignitor can be incorporated into any suitable combustion system, the micro-ignitor is preferably incorporated into a micro combustion engine with a swing arm.

James Rhett Mayor - Ypsilanti MI, US

International Classification:

F01N 1/02

US Classification:

181250000

Abstract:

The muffler system of the preferred embodiment includes an outer membrane adapted to operate in a collapsed mode, wherein the outer membrane defines a first volume that facilitates portability and stowage, and in an expanded mode, wherein the outer membrane defines a second volume, which is larger than the first volume, that provides attenuation and muffling of the noise signature of the power system. The muffler system further includes an inlet coupled to the outer membrane and adapted to allow the exhaust gases and sound waves from the portable power system to enter the muffler system.
