MYT Engine

NASA Winner: Massive Yet Tiny (MYT) Engine design

updated June 30th. 2010 : 6" prototype progress still unknown.

"A 25 lb, 7 inch, MYT engine should give 200 hp at 150 mpg of biofuel, (up to 500 hp with super or turbo charging) and the biofuel, or diesel fuel, also is the lubricant, no oil needed."

Raphial Morgado receives First-Prize in the 2005 Emhart-NASA Tech Briefs "Create the Future" Design Contest
3 April 2006 MYT engine

First-Prize winner is Raphial Morgado of Angel Labs (Acampo/Lodi, CA) for his Massive Yet Tiny (MYT) Engine design. The first prototype model of this internal combustion engine exerts 850 cubic inches of displacement even though the size of the engine is only 14" in diameter and 14" long, and weighs 150 pounds. The level of displacement is achieved through frequent firing -- it fires 16 times on one rotation, making it equivalent to a 32-cylinder, four-stroke engine.

"With a ten million dollar loan, we can launch our pilot production facility and another industrial revolution, ..."

Unfortunately, 2007-2008, was spent building new facilities, nothing was happening. Still no working prototypes.

The engine is highly scalable - it's easy to adapt for both very large and very small applications. For instance, we performed a design-study for Exxon-Mobile to replace the 5-story tall diesel engines used on supertankers with the MYT, and replacement design we proposed to them measured only 5 feet in diameter and 7 feet long. This wasn’t even as large as a single piston in the original engine!

In terms of downscaling the design, we can still produce high-output small-scale engines for UAV's or even microgenerators for consumer electronics. These require a high power to weight ratio at a small size, and we can build them as small as 1⁄2 inch in diameter to power all sorts of consumer mobile-power applications.

The MYT engine only has 15 moving components, and the RPM can be set higher because there aren't any reciprocating parts or cylinder heads with valves prone to "valve float". The MYT doesn't have valves, lifters, or a camshaft.

With 32 pulses per cycle and approx 3,000 foot-pounds of torque, the fuel consumption is expected to be 3 to 6 times less because of lower friction and longer piston duration at Top Dead-Center (TDC), which lets us extract lot more energy from every gallon of fuel that we burn.

At Top Dead-Center (TDC), a standard internal combustion engine has zero degrees of duration - in other words, the piston is always either approaching TDC or leaving it, but it doesn’t ever remain there. In comparison, the MYT Engine has a carry-over of 12 degrees at TDC due to the 2 crankshafts' duration at the timing events.                             Above: MYT Engine visualization demo

Biography of Raphial Morgado

from A Win for the Little Guy Over Detroit's Big Boys
by Jeane Manning
Raphial was born in Hilo, Hawaii. His parents had met during the Second World War when his father was stationed in the Philippines. The family moved back there when Raphial was seven, and he lived there until he was 19 years old. Since his father was shop superintendent for a large bus company which built its own buses, oldest son Raphial could hang around any part of the shop. He learned how to overhaul a diesel, fix a fuel injection system, do metal work, and operate a broad range of other equipment. Mechanically inclined and possessing the ability to draw plans, he always had a project underway.

As with many gifted children, young Raphial’s quick mind often landed him in trouble at school. Science teachers in the Catholic school he attended kicked him out of the classroom and sent him off to be punished because he wouldn’t stop asking questions that they couldn’t answer.

Too often such stories end sadly with the gifted child being mistreated, quitting school, and becoming cynical and even embittered. Raphial, however, was lucky. When a frustrated teacher would send him to the principal’s office, he received soothing advice from the priest in charge. Father Gabriel said, “I know you’re a special kid, just like your father has special wisdom. God gave you gifts. But be more careful with your teacher; don’t ask all those questions.” Instead of a whipping with a stick, the boy received understanding, validation, and some chore to do in the principal’s office.

Later, a chaplain in the Armed Forces was the source of advice which Morgado remembered when he got out of the service. “Get busy or go crazy.” For the next two years Morgado was a sheet-metal worker and pursued his hobby of drag racing in off-work time. Drag racing is hard on engines, and he tired of engine after engine blowing up; so he worked on improving them in whatever spare time was left.

One day he realized, “My garage is full of projects. How did this happen?” His expertise with engines had led race car owners to ask for his help; and eventually, the demand for his services caused him to quit the day job and go into business as a mechanic. While servicing expensive cars, he made house calls even at night, and met clients who became personal friends. Jim Givens, for instance, was still in law school when he hired Morgado to work on his Mercedes. Givens introduced Morgado to patent attorneys, gave him valuable advice, and has been with Angel Labs from its beginnings to the present.

He had long ago decided that no matter how exciting the idea seemed, he wouldn’t develop any invention unless there’s a market for it. The new engine concept arose out of the need to redesign racing engines. In a flash of insight and twenty-minutes time, one day he drew the toroidal (donut) shapes and how the new piston arrangement would work. There would be no need for valves. Perfecting the design for the timing mechanisms, however, took two years.

Morgado had been earning the level of income that later allowed him to develop the air driven "demonstrator" of a paradigm-changing invention independently. He bought a five-acre ranch including buildings that he filled with expensive expensive tools and equipment for a production line. After he spent his own money, funding came from family and friends and then friends of friends.

Building a 5.5 6-inch Prototype

MYT engine to be demonstrated to Society of Automotive Engineers International (SAE)

Nov 18, 2009
Guest Speaker at Oregon SAE March 20, 2010
April 8th. May 15th. 2010 CANCELLED, April 20th
"The date has been indefinitely deferred - till a prototype is built and running."

The inventor, Raphial Morgado, had been invited by the Oregon Section of the Society of Automotive Engineers International (SAE) to be the guest speaker at their annual event in Portland on March 20, 2010 from 12-2 pm.

Due to a two month delay in getting the gears for the small motors, Morgado was set back in his time frame; and rather than reschedule the SAE Oregon event again, SAE opted to cancel it for now, with the possibility of scheduling something again in the future, once everything is running and ready to go.

April 8th. 2010

"As the 5.5" MYT was being fitted with the timing gears, it became apparent that the gears were getting too small and that strength might be a factor. . . . we decided to play it safe and grow the engine up to 6", adding more material not only to the timing gears but also for the remaining internal parts for added strength." - Morgado

Scrambling to get his 6" (inch) version of his massive yet tiny (MYT) engine ready to demonstrate to the Oregon Society of Automotive Engineers (SAE) annual meeting (re-)scheduled for May 15, Raphial Morgado discovered that he can make a 6-inch motor using regular machining processes, so he will not have to go to the expense of creating a casting: "very expensive to gear up for". In normal, mass production, of engines, a block is cast in order to be more affordable. He still believes the larger motors will require casting; but now he has a version he can quickly build into a prototype.

The first 6 inch prototype

Morgado said he was amazed that the way they are building the 6" MYT in a one-off process, is actually more practical and cheaper, than the more extensive multiple operations that casting requires. Furthermore, Morgado notes that casting is not as strong as machining from a solid billet.

He still thinks the larger engines will still require the establishment of a pilot production line using casting.

Another unintended advantage that has emerged is that the various relationships that Angel Labs has established in the process of building the 6" motor, can work toward going into initial production.

Morgado concludes saying: "By the time you see a complete 6" MYT running on fuel, it means that we are in fact successful not only in building the 6" MYT Engine, but more importantly, we are in manufacturing mode without further need of the 10 million dollars [we had thought would be] required to set up a pilot production line."

[ The unfortunate reality is that he is still in a learning, "discovery", mode. He is discovering that he is not a mechanical engineer. He does not know the strength limits of the parts he has specified in his design(s) (namely his gears!) Hopefully he will learn, before he makes any more serious mistakes like that, the importance of building his prototype and "getting the bugs out" before going into production, before it is too late - and his mistakes "burn" his investors.

It is now mid July 2010 and there is still no news. Shall we guess that he is still discovering more parts that he has not sized correctly for the load(s) they will be bearing and having to re-design "the whole thing" again (!) to accommodate the now even greater loads of the newer-larger design?! ]

There appear to be some significant issues that could stand between it and mass production, however. First, forming the toroidal "cylinder" doesn't look to be a trivial task, as the toroid must be split in two. Getting the two halves to form a perfect circular cross-section would seem to be quite a feat. There's also the issue of producing the indexed motion of the two piston pairs, which is certainly not a straightforward affair. Combine this with the claimed output torque of over 800 ft-lbs., and we see a potential durability problem.

The size of the engine also yields its own problem, in that there does not appear to be sufficient material to support the type of output that the inventor claims. There are good reasons that every other engine appears monstrous in comparison to the MYT, and we don't think it's because current engine designers lack an understanding of material characteristics. It's not just important to understand the ultimate strength of the material and construction something to withstand a single cycle, but fatigue must also be accounted for in any design that's expected to withstand literally billions of cycles. While there are several high-strength materials that may be able to provide adequate strength, they are typically not used in internal-combustion applications. Then there's the matter of lubrication and cooling, both of which seem problematic given the "cylinder" configuration.

None of this commentary is intended to disparage the work that Raphial Morgado and his team have put into this engine, of course. We here at Autoblog prefer to take an optimistic view of the internal combustion engine's future. Certainly, we'll all benefit if indeed Morgado can make his invention work in a cost-effective manner that allows it to be brought to market.

A blogger, on another blog, mentioned "sand casting". Everyone should go to Raphial's web site and tell him and his "people"
Ray says:
Try using sand casting. At the Ohio State Fair, several years ago,there was a sand casting demo. The demonstrator invited any one to bring him an object to sand cast.

I remembered a 3 or 4 inch skillet and that it was my mother in law's birthday. I went home, got the skillet, added raised lettering, saying 'happy birthday'. Took it back to the fair, for sand casting. The demonstrator cast an exact replica, make of cast aluminum, showing the added 'happy birthday'. I was able to give her a solid aluminum skillet and birthday greeting in one.

This should work for other metals, as well. It would certainly be worth checking out. Casting sand is relatively cheap compared to the alternatives. Good Luck.
