Default Nitro to e85 conversion?

Has anyone completed this swap? What modifications are needed? I attempted to do some research but the only real detailed article I was able to find was on a model plane's engine and he used a spark plug.

Here is the link to the model plane thread: rcuniverse.com/forum/m_6479059/anchors_6479059/mpage_1/key_/anchor/tm.htm#6479059

The vehicle we are trying to convert is a 1/8th scale Kyosho Inferno GT with a GXR 28 4.6cc engine.

Thanks for any help!

I'm not sure it could be made to work with glowplug compression ignition. Maybe, just not sure.

One thing I do know, much less power.

Also, the gasoline might eat the o-rings. Not sure what material ours are made of. Some can take gas but not alcohol. Some are good for alcohol but not gas. Only a few materials can withstand both.

Would bio-diesel work any easier?

Why are you trying to do this?

E-85 is 15% gasoline, and 85% ethanol

20% nitro fuel is 20% nitromethane, and 74% methanol (the other 6% is lubricant, and that number changes with the type and brand of fuel)

So if you're going for some sort of green fuel you're on the wrong track.

You could get a 1/5 scale car to run E-85, but at that point you might as well run 100% ethanol.

From the teacher of the class I am trying to do this in.

Quote:
You may ask, "why does Dr. D want to run ethanol" if it is going to be a pain.

* Methanol is extremely toxic - one teaspoon can kill a normal person
* Cellulosic ethanol is a future fuel that could have a large impact on reducing greenhouse gases

I do not care how much power or how well the engine runs. I would just prefer that the engine runs on a fuel that shows future potential. Ideally, in the future we can get CPE students involved to make cellulosic ethanol to run in our engines showing even more collaboration between different departments.

I DO NOT CARE if you destroy that engine we have on the 1/8th scale car trying to get it to run E-85. What you might want to do is build a small test stand to separate the engine from the car and test different combos of E-85 and lubricating oils (like castor oil). If the engine dies, in the immortal words of Ivan Drago: "If he dies, he dies".

Ok, personally I wouldn't mess with E85 at all. Straight ethanol with maybe 10% oil, half castor half synthetic (Klotz Techniplate and Benol is probably the easiest for you to find).

To get it to run right you will probably need to pull a couple head shims and run the hottest plug you can find. With a good tune on the carb it will probably run fairly well.

good start maybe a new shape to the cumbustion camber in the head button maybe a dome to the piston and make some power

I say run straight ethanol and oil in a PRE WARMED engine. it needs to be pre warmed, as I can't see it igniting without vaporising first. Stick the engine in an oven at 100C and see what you can do.
