Cyclone Mark V Engine

The company Cyclone Power Technologies of Pompano Beach, Florida was founded by inventor Harry Schoell to develop and market this engine.

The Cyclone Engine is built of three major components, the Steam Generator, Piston Block, and Condenser.

[29] Steam Generator has three basic components: a coil of water tubes, surrounded by a series of burner assemblies, and covered with an insulated shroud.

[30] Cyclone Power Technologies claims this arrangement allows the heavier particles in the fuel to circle the outside of the chamber until they are completely burned up, allowing for much cleaner, complete combustion of fuel, and resulting in cleaner emissions.

This valve is actuated by a variable cam on the crankshaft, and allows for the entrance of supercritical water into the cylinder.

As the supercritical water enters the cylinder it flashes into steam and pushes the piston inward, thus rotating the crankshaft.

[34] This improves engine efficiency as less fuel needs to be burned to heat the combustion gasses to a given temperature.

This transfers some heat to the water before it enters the steam generator, further reducing the amount of fuel necessary.

The carrying capacity of a journal bearing is a direct function of the dynamic viscosity of the lubricating fluid.

Cyclone Power Technologies had contracted with the Ohio State University Center for Automotive Research (OSU-CAR) for engineering analysis.

A March 8, 2014 presentation [36] by OSU-CAR described the engine bearings as a "critical path issue" and stated: The contract between Cyclone Power Technologies and Phoenix Power Group for the lower output WHE steam engine[21] states that Phoenix Power Group will make a $150,000 progress payment "Upon the completion of 200 hours of durability testing of WHE version 5.0 as conducted and/or overseen by OSU.

As of February 28, 2015 there has been no indication they have made a water lubricated engine pass this 200-hour endurance test.

"[38] However, in the 2013 Annual Report, they state: "We have not yet performed this testing on our engines to meet any existing emission standards of the EPA and CARB.
