Rand Cam Engine Prepares to Power World into 21st Century; Streamlined Engine Delivers Power with more Efficiency, Less Weight and Noise






CLICK4VIDEO(07:00)
LAS VEGAS--May 9, 2005--Money Show, 2005/Booth 111--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 US (OTCBB:RGUS) and Reg Technologies Inc. (OTCBB:REGRF) 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 H.P. 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 and its US subsidiary, REGI US. "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."

oooh no frickin way. This is very very close to the engine that came to me in my dream a couple months ago. Damn this is like the 10th time this has happened to me.

rx8wannahave

WOW...cool, any new rotary...is a good thing!

rx8wannahave

What are you...one of those "inventors" commercials, LOL...just messing...

Photic

I do have one that I have been meaning to get a patent for. I found out there are some things that are similar to it, but not quite.

TheColonel

I'm looking at the picture and I'm not getting it...

rx8wannahave

Per the Video, this new rotary engine has 30% efficiency compared to a piston engine or Wenkel rotary, which have only 10%. So...it makes much more power per pound and is (maybe a rotary first) more fuel efficient to boot.

What makes this interesting to me is that they plan to use this type of "Round" Rotary in all sorts of systems. AC systems, planes, boats, and cars are all on the list of future or current testing. Very interesting!

Wurmfist

It is curious, but being a realist I think we see lots of prototype engines that claim this very thing, only to fail in actual testing. I will watch this with interest though.

N8theGr8

Not to highjack the thread but you better hurry. I made an invention for a science fair when i was in ELEMENTARY school and didn't think anything of it after that. Guess what I saw at Home Depot selling for $25 a peice last week

N8theGr8

Yeah I dont know if I see this in an aviation application like they are claiming. No combustion engine is going to put out more power than the available jet engines we have today. And as for its quiet capabilities there are aircraft putting out much less than 60db from 1500 feet already.

Thetitanium8

very interesting.

Most piston engines are actually between 25% and 30% thermally efficient. I'm not sure on the exact number for the Wankel, but I'd be surprised if it was below 15% once warmed up and is probably around 20%.

gasoline engines are almost 95% or greater efficient at low highways speeds. it's the starting out and drag that kill the efficiency.

this is why hybrids have such a good rap. they capture you energy while stopping and return your car to motion, using the energy you generated absorbing the enertia of the car. they also cut off the engine while idling and most hybrids so far have some of the least drag co efficiencies ever made in production vehicles.

diesels also have about 20% more energy per gallon than gasoline. plus they tend tolast longer. europe is already almost 40-50% diesel. the US is lagging far behind with it's love for gasoline engines.

PoorCollegeKid

Gasoline engines are nowhere near 95% efficient at highway speeds. Even the huge diesel engines used in ships can barely scratch half that value, and diesel fueled engines, as you said, are much more efficient than gasoline fueled ones. An engine runs most efficiently at WOT at its torque peak, and for most engines (including those in hybrids) this comes at a relatively high rpm in order for the engine to put out a decent amount of power. On a highway, an engine is usually running far away from it's torque peak with a nearly closed throttle, and so is producing power far less efficiently than its 25%-30% rating rather than doing so far above this number.

The big problem with diesel engines is that they pollute far more than gasoline engines of similar power ratings do. These engines will take off in the US when our diesel fuel gets to be as clean as the fuel found in Europe, allowing cleaner, smoother, more environmentally friendly diesels to be marketed. I believe that diesel fuel must meet these new cleanliness standards at some point during the next decade or so, and I would not be surprised to see the introduction of diesel vehicles on a European scale soon after that, especially if gas prices continue to climb.

The engine's got two types of moving parts: vanes and rotors, well, 12 vanes and 1 rotor. That's a lot of moving parts. Warping one of those vanes or blowing a seal will cripple that engine pretty quickly. It's an elegant design and an interesting take on the Otto 4, but still no Wankel with only two moving parts. I'll reserve judgement until their major government and bus air-conditioning units hit the market. I'm no Warren Buffett, but I say it's still too early to be investing in OTC.BB: RGUS

new engine designs come out every year...this one seems highly suspect

I'll believe it when I'm driving down the highway with it :p

s13lover

Felix tried many designs before he settled on the trochoidal rotor in the epitrochoidal housing. Many other manufactures supported this design, including companies that did not use his patent for their developement. I'm hard pressed to believe that any of these other rotary designs work better at internal combustion than the good old "wankel."

Just another variation on the same theme. Lots of these upstart companys have big dreams of creating the next generation engine for the automotive industry. The bottom line is that NO industry is going to drop 150 years of proven performance and technology for something thats better in a lab environment. I took some engine design courses in school, and after doing some extensive research into my own ideas on rotary power i began to realize why piston engines are the way they are, and will probbaly continue to be for a long time to come. The rotary (wankel) engine is an extremely rare example of a succsessfully overcoming the cooling and lubrication woes of rotary power that isnt a brayton cycle (gas turbine). It (the wankel) could be the only case of of an engine that was mathematically perfect, and perfectly applied.

Just my $.02

Interesting...looking at the compact size and supposed power output, I'm guessing it's got thermal issues if it went to gasoline fueled applications. I wonder what unobtanium alloy is running for on the open market these days?
