Cyclone Power Technologies tests fuel made from orange peels in fuel injector of its Green Revolution Engine
Cyclone Power Technologies announced last week that it has burned a biofuel derived from orange peels in the high-performance fuel injector of its 'Green Revolution Engine', an external combustion engine currently under development.
The 100% natural biofuel is called d-Limonene, an oil extracted from citrus rind. When citrus fruits are juiced, the oil is pressed out of the rind and distilled, resulting in food grade d-Limonene. After the juicing process, the peels are conveyed to a steam extractor which collects more of the oil from the peel. When the steam is condensed, a layer of d-Limonene oil floats on the surface of the condensed water. This is technical grade d-Limonene (schematic, click to enlarge).
d-Limonene is a very versatile chemical which can be used in a wide variety of applications. As a straight solvent, d-Limonene has found use as an alternative to mineral spirits, methyl ethyl ketone, acetone, toluene, glycol ethers, and fluorinated and chlorinated organic solvents. Much of the product goes into making paint solids or as a secondary cooling fluid. With record-high oil prices, the product has become a biofuel that can be used directly in combustion engines.
Cyclone Power Technologies tested d-Limonene in its Green Revolution Engine (image, click to enlarge) and found that it atomized efficiently through the fuel injector, produced a clean burning flame, and registered a BTU level almost 500 units greater than kerosene. Equally important, the test required no modifications to the fuel injector, demonstrating the versatility of this critical component of Cyclone's engine:
energy :: sustainability :: biomass :: bioenergy :: biofuels :: citrus :: d-Limonene :: external combustion engine ::
"Our fuel injector is based on a technology known as High Turbulence Siphon-Type Air Atomization, which emits a small micron gasified particle," stated Michael Hodgson, Cyclone's chief engineer. "We can ignite the bio-fuels on and off like a light switch and they are very clean to burn."
Over the next few weeks, the Company plans to test other alternative fuels in its fuel injector, including biodiesels produced from palm oil, cotton seed oil and chicken fat, as well as ethanol, which is produced from corn.
"We're very pleased with what these results tell us about our fuel injector," stated CEO Harry Schoell. "We're also pleased with d-Limonene, which burns hotter and cleaner than kerosene, and also makes the entire test area smell like oranges."
Cyclone holds the U.S. patent, international patent applications, and exclusive commercial rights to the Green Revolution Engine, an environmentally-friendly and highly-efficient external combustion, heat-regenerative engine.
The Green Revolution Engine regenerates (or recycles) its heat, which allows it to run cleaner, cooler and more efficiently than traditional internal combustion engines. It is capable of running on any liquid or gaseous fuel, including ethanol and propane, and is lubricated with de-ionized water instead of motor oil.
By eliminating many subsystems like oil pumps, radiators, catalytic converters and fuel injectors, Cyclone's Green Revolution Engine is expected to cost less to manufacture, operate and maintain; however, it is highly scalable and sufficiently powerful for applications ranging from lawn equipment and small home generators, large stand alone generators, to cars, trucks, buses, RV's, boats and ships, as well as earth moving equipment and locomotives.
