SO, where is this new Engine?
 

I have read about this Enya engine for some time now. Does anyone have one? Or even more data on one. Here is the link>>>>>> http://enya-engine.com/180XGS_E.html Thanks Capt,n

RE: SO, where is this new Engine?
 

I'm fairly certain that it's still in production. If you really want an answer, why not email Ken Enya himself?

RE: SO, where is this new Engine?
 

I'm not as interested in the new engine as I am the new glow plug that will stay lit while burning gasoline - if I understand things correctly. Think of the problems that could eliminate by eliminating spark ignition systems altogether.

RE: SO, where is this new Engine?
 

That is why I was interested in the New1.80 Enya. Also no need to buy a extra battery to run a ignition system & all the other parts to complete a ignition system. Then there is the extra maintenance of a ignition system. Best Regards, Capt,n

RE: SO, where is this new Engine?
 

It may not be intended for the USA market?

RE: SO, where is this new Engine?
 

You may be right about not being meant to be sold here in the USA, although I can't imagine why they would think something like that.

However, once it is known that a glow plug can be manufactured that will function properly while burning gasoline and with no battery voltage being applied after start up, then others will pursue that line of research. After that, it will only be a matter of time until such glow plugs are available globally - assuming that the price can be kept reasonbly low.

I can well imagine utility engine folks adopting this technology for their weed whackers, etc. Just think, all you would need is a C cell to start the device. Less overall weight and no problems with folks that can only limpwrist on the starting cord.

Ed and Gents,
I do not want to disturb your party but there is only one thing I think about, the standard two stroke glowers!

So a Warning

In this era of the fuel spitting engines (Ed, your Thunder Tiger .46 Pro for example!) and on board glowers I think it can be dangerous to use gasoline in a standard glow plug 2 stroke engine. Because of the primitive gas factories there often is a lot of unused fuel residue in the exhaust gases and that can transform a plane in a flame thrower I am afraid.

I think you need a (suction!) pressure controlled carburetor like the Walbro or similar and not the uncontrolled muffler pressure on tank and open spraybar needle valve when trying such a plug in a “standard” glow plug engine.
Also very important can be, don't use "on board glowers"!

With the air/fuel ratio of gasoline being 14:1 and whereas the air/fuel ratio of nitro glow fuel being in the area of 6:1 with all the extra oil, I think you will find the extra fuel out the muffler to be greatly diminished on gasoline but none the less still present.

RE: SO, where is this new Engine?
 

I got a reply from Ken Enya . He said the Glow plug gas version will be released in the end of October or November. That sound interesting! I love modern technology! Best Regards, Capt,n

RE: SO, where is this new Engine?
 

I wonder if the O.S. BE-3 Glow Plug designed for the Bio Ethanol Engine would work...

RE: SO, where is this new Engine?
 

That is a good question.

Perhaps this gasoline intended glow plug is a spin-off of the ethanol glow plug technology? Or not?

I have tried to run glow engines (methanol fueled) on lots of different fuels over the years, but especially as a pre-pubescent youth. We did, indeed, experience some serious fires. My neighbor lost a brand new model airplane to such a fire and it wasn't some RTF plastic POS either. Fortunately, none of us were seriously burned.

w8ye.

I was not thinking about a running engine, only burning!!!

Kei Model, (the only place that I know of) that sells the Bio ethanol OS engines is sold out of the 75 and 120 sizes.

I think this is doable by tinkerers - start with a hose nose plug like a OS F or Fox Miracle.

A guy on this forum is mixing naptha with glow fuel at a 50:50 ratio (oil content appropriately adjusted) and says it runs well, with lower cost, lower fuel consumption and a very modest power drop. Sounded good, but now you've got me thinking...wouldn't that also be a recipe for a flying flame thrower?

I remember at the start of 1/2A Texaco guys would mix gasoline in with their glow fuel to get ridiculously long runs. Then a rule change outlawed it because the planes stayed up too long.

If this was a problem, they would have run into it many many years ago with model ignition engines in the 1920's, 1930's, 1940's and up till present.
The Walbro pumper carbs was a relatively new use on the ignition engines that started in the late 1970's.
Heck I used to think it was bad to hook up muffler pressure on a gasoline ignition engine that didn't use a pumper walbro style carb, but it works fine anyway. the proper air-fuel ratio for igntion of gasoline inside of the fuel tank doesn't appear to happen. Besides with the exhaust gasses, there isn't much if any oxygen inside of the fuel tank to cause a problem as well, the highest risk is with the fuel tank nearly empty, and it has to contain fresh air not exhaust gasses.

Now it works best with a longer intake tube on the engine's carb. It was quite popular to stick on intake stacks to help improve the carb's effectiveness. Using the Bru-Line air filters had a similar effect too. These reduce the spitting of fuel from the carb when the engine is running.

Probably the biggest problem is a glow engine uses a carb calibrated for the more rich methanol glow fuel and not gasoline which uses a more lean mixture ratio, sometimes this can cause problems with adjusting the engine.

RE: SO, where is this new Engine?
 

I have a couple of the Enya Gasoline Glow plugs and plan to do some experimenting in the next few weeks.

The plugs look very much like an OS-F but are slightly longer.

The thread is also a much finer metric thread, so you can't use the plugs in an engine with std 1/4x32 thread.

Enya sell the engine with a 100% Ester based Synthetic oil which they call something like Chemosynthesis but i don't know if the oil is a neccessary ingredient for the catalytic heating of the plug. That is what i intend to find out.

RE: SO, where is this new Engine?
 

I am looking forward to reading your reports concerning Enya's new gasoline intended glow plug.

As the previous poster stated about gasoline spitting from the carbs and its danger, I have seen more than a couple of model airplanes go up in smoke after catching fire, but this was with both gasoline and methanol fuels. Mostly control line models, back before electric starters were conveniently available. At least one can see the gasoline fueled fire's flames. It is weird watching a methanol fueled model begin to bubble and contort before the wood catches fire and explains what is actually going on.

RE: SO, where is this new Engine?
 

I tried Naptha/Coolpower mixing 10% camp fuel . I had to add ester oil to make it mix but it did cut fuel flow requirements noticeably. Only problem is the plug would go out and not relight after long power off downlines.

RE: SO, where is this new Engine?
 

Good research guys. Kweasel, what is ester oil???

Thanks,

Ernie

RE: SO, where is this new Engine?
 

Ester is used exclusively in turbine engines and many airconditioning systems. It tends to mix well with anything.

RE: SO, where is this new Engine?
 

Airconditioner oils are mostly polyalkylene glycols (PAGs), the same stuff used as "synthetic oil" in glow fuels. "Ester" sounds too broad - an ester is when you combine organic acids and organic bases (or alcohols) - most fats (e.g. castor oil) are (tri)esters.

I am really glad to see you back in print in a hobby related forum. It has been a while since I saw you on rec.models.rc.air. I always enjoyed your posts.

RE: SO, where is this new Engine?
 

Weird indeed! My only model engine fire was with a CL stunter with a fully cowled, inverted Fox. On the first flip I heard a sort of "Whumph!". Then the paint around the edge of the cowling started to bubble just as the hair on my forearm went up! Fortunately the fire was quickly smothered with a rag.

I have seen a couple freeflights go up in flames due to careless lighting of the dethermalizer fuze.

RE: SO, where is this new Engine?
 

You know in all my years of flying model airplanes I haven't seen one catch on fire yet. Now I have seen others, and I myself included,  have put in planes at full speed into the ground or pavement, and still none of them ever caught on fire on us. The only planes on fire that I have seen were with the  fan jet planes that crashed after having a failure in the air. Those jet engines tend to be really hot too.  I would assume quite a few jet flyers managed to catch their plane on fire getting the jet engine to start too, with the flame shooting out the back rather impressively. Usually they all have fire extinguishers handy with those jets though.

Now I did witness a few electrics having a failure of one sort or another resulting in a fire as the battery pack and or ESC burned up. I always thought it was pretty interesting hearing a loud pop, then seeing the smoke trailing from the plane while it goes down, as the pilot says he lost it, he doesn't have control, etc. But this wasn't common though and still was a more or less rare event.
