Discussion Overview

The discussion revolves around the "Massive Yet Tiny (MYT)-TM" engine, focusing on its design, potential flaws, and the feasibility of its claims. Participants explore various aspects of the engine's mechanics, its comparison to existing technologies, and the implications of its proposed operation.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants express skepticism about the MYT engine's claims, suggesting that if it seems too good to be true, it likely is, citing the need for mechanical reliability.
  • Others note that the engine does not claim perpetual motion or over 100% efficiency, but may face practical challenges similar to those of existing engine designs, such as complexity and wear.
  • Concerns are raised about lubrication issues due to the design of the pistons and their exposure to combustion, which could lead to leakage and reduced efficiency.
  • A participant highlights potential flaws in the patent drawings, questioning the functionality of the oiler rings and their interaction with the engine's ports.
  • Another viewpoint suggests that using two-stroke oil might mitigate some lubrication issues, drawing parallels to existing two-stroke engine designs.
  • There is a shared concern regarding the absence of a running prototype, with some participants questioning the viability of the engine if it cannot be demonstrated effectively.

Areas of Agreement / Disagreement

Participants generally express skepticism about the MYT engine's practicality and reliability, with multiple competing views on its design challenges and potential solutions. The discussion remains unresolved regarding the engine's feasibility and effectiveness.

Contextual Notes

Participants note limitations in the design's assumptions, particularly regarding lubrication and mechanical reliability, and highlight the need for further empirical evidence to support the engine's claims.

Hi Folks,

I've been enjoying the time off work for the holidays, and trying not to think about engineering and stuff... but once it becomes a way of life it is hard to stay away from it. I just found the following on the "Massive Yet Tiny (MYT)-TM" engine. I am only now starting to look over this whole page, but I am wondering if anyone else has run across it and if they have found any flaws in either the analytical model or the figures that describe this patented device?

It seems to good to be true, and that always raises flags. But I have read a claim that it has been run on a calibration dyno to verify its torque output. Anyone know anything? Thanks,

Rainman

If it seems too good to be true, it probably is. There is no free lunch.

The presentation is rather vague, but there is quite a bit of start-stop motion, pistons advancing to a position, stopping, and then advancing again. One has to ask what holds them only to allow them to advance again? The mechanism that would allow this seems likely to be prone to mechanical failures, so again, there is no free lunch.

Don't spend your lunch money on stock in this venture.
 
It's not outright snake oil - it's not claiming perpetual motion or >100% efficency.
It takes some ideas from the Wankel engine and Deltic diesel - but is likely to have the same problems in practice as they do, complexity, lubrication, wear and precision etc.
 
Anyone heard anymore about this?
 
There is actually another thread about this somewhere nearby.
 
ooer, anyone got a link? Ill try searching again.
 
I like the design. It's cute. But the problem is that the new orientation of the pistons causes a whole new slew of problems. You have rings that get no lubrication because both sides are exposed to combustion. The pistons connect to their linkages through the cylinder wall which provides a place for leakage and leak-by. These are not insurmountable problems, but we've had 100 years to fix the similar problems on conventional engines. Since we already have cheap conventional engines and we don't have 100 years the MYT engine has to be better and cheaper in a very short period of time and with only a small amount of money for R&D otherwise regardless of it's potential it will fail.
 
chayced,

Some good points. Prompted me to take a closer look at the (very detailed) patent drawings at;

http://www.rexresearch.com/morgado/morgado.htm

The rings (# 70 in FIG_14) would not actually be "rings" - more like ~330 degree crescents. They could be oiler type "rings" supplied through gallies machined in the rotor/piston. (Note: FIG_14 appears to me to be incorrectly drawn. If (for example) the ring is mounted on the piston which is part of the rotor (69) on the right, then you should be able to see the ~30 degrees of the ring which is covered by the left rotor (68) in the figure.)

A question arises here - what about the oil pressure/flow as an oiler ring passes the inlet and outlet ports? An oiler ring perforated in this location would spray oil into the intake and exhaust ports. A ring which is not perforated at the apex to prevent the above, would wear out sooner.

Gallies would also need to be machined in the rotors to supply the ring (76) in the annular grooves (68c & 69c) between the rotors and the rings (77) in the annular grooves (68d & 69d) between each rotor and the central section and end cover (52 & 53). These three rings (which complete the seal of the toroidial cylinder) are not so problematic.

Hmm... Would work great if you throw some two stroke oil in the gas. Come to think of it, don't two strokes run the rings across the exhaust port? Maybe this isn't such a far fetched idea. Running off a good slick diesel It might work without oilers. Still need oil for the rotors, but that's not insurmountable. Sure hope we see this one again.

But again, it still has 100 years of catching up to do in a very short period of time.

The thing that really has me worried is that we have yet to see a running prototype. No running on compressed air does not count. The idea seems sound but if they either haven't been able to get it to run or have problems so severe that they cannot display it yet then it may already be a lost cause.
