SMALL INTERNAL COMBUSTION ENGINE FUELS

Abstract

Disclosed herein are motor fuels providing enhanced properties for use with 2-stroke and 4-stroke engines. The fuels comprise isooctane, alkylate, mesitylene, isopentane and butane, and optionally a special lube oil premixed in solution.

Claims

1) 4-stroke fuel comprising Isooctane (40-65%), Alkylate (15-30%), Mesitylene (0-15%), Isopentane (10-20%) and Butane (0-5%).

2) A 2-stroke fuel taking the compositions in claim 1 plus up to 2% w/w % special lub oil premixed in solution.

3) claims 1 and 2 with a fragrance enhancing additive and/or a color dye.

[0008] Experiments were then performed comparing conventional (store-bought) versions of these 4-stroke and 2-stroke fuels including:

TABLE-US-00005 4-Stroke 2-Stroke Trufuel 4-stroke Trufuel 2-stroke (50:1) 93 Autogas (w/o ethanol) Husqvarna 2-stroke (50:1) VP Racing 4-stroke Echo Power 2-stroke (50:1) 100LL avgas VP Racing 2-stroke (50:1)

[0009] The testing showed our fuel had no gumming, no deposits on the spark plugs, no toxic chemicals, no aromatics and no visible smoke, with rapid starting (within first 2 vs. up to 11 times for others), 60-90% less carbon monoxide emissions, smooth idling and no harsh smells. Each of the competitive products had signs of deposits, visible smoke, slow/unreliable starts and strong smells. The 100LL contains tetraethyl lead. The auto gas and avgas both contained aromatics up to 25%. Many of the fuels contained unspecified middle distillatesbut not pure fuel components.

[0010] Consumers found our fuel to be highly cost effective by lowering the cost of additives and special treatments (attempting to overcome fouling and gumming), and the elimination of unnecessary engine repair bills and lower overall equipment maintenance costs. Emergency workers also stated the reliability of the engine starting of this formulation was a clear and remarkable difference. Outdoor users also appreciated our use of a fragrance and dye for special applications.

[0011] Additional engine results were obtained for the ultralight and UAV aircraft engines which showed . . . .

[0012] We believe this unique set of formulations is widely beneficial to all 2-stroke and 4-stroke engine users including fire departments, municipal governments, military and civil UAV flyers, ultralight hobbyists, outboard motorists, lawn and garden firms, winter sports shops, summer recreation shops, commercial businesses, motor cyclists, property owners and residential homeowners.
