Rand Cam Rotary Engine

Regi U.S. Inc's Rand Cam (TM) rotary engine is a piston less rotary engine that functions by using two opposing and identical disc-shaped rotors that are offset by 90 degrees around the central shaft.

These rotors have a sinusoidal side profile with two "bumps" and two "valleys". Both rotors turn in the same direction within the housing and are separated by a central section. Inlaid in this central section are 12 vanes that can slide between one or the other rotor housing but do not turn with the engine's rotation. Since both rotors are offset and opposed, the straight-line distance between the two rotors is always the same. This allows for the vanes to move from one side to the other without breaking. The rotors are also called Cams, due to the camming action they use to move the vanes.

As opposed to a Wankel engine, which has a moving combustion chamber, the rand-cam engine's combustion chamber is fixed due to the stationary nature of the vanes, yet varies in size due to the rotor's motion.

The Rand Cam (TM) rotary engine is reported to be lighter, more efficient, and quieter than a traditional engine, the Rand Cam (TM) rotary engine produces three times more power per pound of weight than the piston engines that dominate today's market.

Positioning itself to provide engineering solutions to modern day industries and consumers, Regi U.S., Inc - Reg Technologies Inc. has recently announced the successful testing of their patented Rand Cam (TM) rotary engine. The streamlined, four-stroke engine creates continuous injection and combustion in a single chamber, powered by just two types of moving parts (the vanes and the rotor). Because of the simplicity of the engine's design, the Rand Cam (TM) is able to generate 24 cylinder firings per rotation and provide continuous power that is vibration-free and extremely quiet.

Traditional combustion engines require separate chambers for intake, compression, combustion, and exhaust, and even a simple four-cylinder piston engine is comprised of 40 different moving parts. The complexities of these engines make maintenance time-consuming, and their wearable surfaces often require replacement after a relatively short period of time. But the Rand Cam (TM) operates with a simplified design and minimal moving parts, reducing the need for maintenance and improving the engine's overall efficiency.

Military and Commercial Applications

The Rand Cam (TM) engine is currently undergoing production model development for possible use in military spy planes, largely because of its compact, efficient, and ultra-quiet design (at 1,500 feet the Rand Cam (TM) engine emitted only 60 dB). Alexandria, VA- based Radian Milparts, Inc. has already built a 42 HP diesel Rand Cam (TM) engine for use in unmanned military vehicles, and the engine is currently undergoing tests by REGI- Rotary Engine Specialists in Richmond, British Columbia.

In addition to the interest among members of the US defense community, the Rand Cam (TM) engine offers many possible commercial applications as well. REGI US has already built an air conditioning compressor for use in commercial transportation vehicles, sparking interest from the Trans Air Manufacturing Corporation, a PA-based company that provides climate control systems for buses. The company is currently testing the Rand Cam (TM) for baseline speed, performance, and air consumption prior to installing a working prototype as a compressor for a bus air conditioning system. In addition, Rand Cam (TM) motors can be used in the nautical community, powering yachts and other boats in place of traditional combustion engines.

The Rand Cam (TM) engine can also be used as a generator, running on propane or natural gas and providing a backup power source for residential markets where power outages are frequent, or carry health or safety concerns. Generators powered by Rand Cam (TM) engines run on propane or natural gas and produce enough power for the average family home, all the while maintaining their compact portability (a Rand Cam (TM)- fueled generator is approximately the size of a microwave oven) and quiet efficiency.

One of the most anticipated uses for the new technology is among the blossoming hydrogen-powered automobile industry. The development of the Rand Cam (TM) engine has sparked considerable interest among environmentalists and eco-friendly manufacturers because of its ability to operate using a clean-burning hydrogen fuel cell. "Hybrid electric vehicles and engines that run using cleaner-burning fuels such as hydrogen, propane and natural gas are the future of the automotive industry," said John Robertson, CEO of Reg Technologies. "Our society has recognized the benefits of exploring hydrogen-based technologies, and we are happy to be contributing towards the development of more sophisticated engines that operate using hydrogen and other clean burning fuels."
