Doyle Rotary Engine, LLC
Red Oak, TX 79413, US
The internal combustion engine powering today’s cars and trucks is a product of more than 130 years of evolution in the hands of brilliant engineers. Every portion of the modern Otto cycle engine has been painstakingly tweaked to perfection in order to make the engine as efficient as possible. While the progress made has been remarkable, the conventional Otto cycle layout has a few inherent flaws that engineers have had to patch by compromising power and efficiency.
The Doyle Rotary Engine uses a split cycle layout that eliminates many of these flaws and allows for many improvements that are impossible in a conventional engine where all four strokes are completed in a single cylinder. In a recent computational cycle analysis completed by engineers from the University of Texas at Arlington it was determined that by running a higher expansion ratio, the DRE could realistically reach 50% efficiency, dramatically decreasing fuel consumption rates.
To date, the project has been entirely funded and developed by the inventor Lonny Doyle. The business incubation services of Center for Innovation in Arlington, Texas helped move development through the first stage of computational analysis. The next goal of the partnership is to seek funds for prototype development (including computational fluid dynamics analysis) and to pay for patents to better protect the intellectual property.

Engine technology licensing
After refining prototypes and perfecting the Doyle Rotary, the technology will be licensed to engine manufacturers in fields including but not limited to: automobiles, small aircraft, recreational vehicles and power generators.
Lonny Doyle wears many hats when it comes to the Doyle Rotary Engine. He started inventing the engine over 28 years ago and has been the sole developer and prototype fabricator since then.
He has used over a decade of experience as a race engine specialist and his machining ability to move the engine forward with limited funds.
