I have an engine with gasoline run through it but I want nitro to run through it, I'm assuming the best idea would be to clean it first but with what?

Engines are designed to run either on gasoline OR glow fuel. I assume when you say 'nitro' you mean glow fuel. You can't just switch between the two fuels without making mechanical changes to the engine. I am not exactly sure what changes are required to switch to a different fuel, but I'm pretty sure you at least have to put on a different carburator.

Ditto, gas air/fuel mixtures differ dramatically from nitro air/fuel mixtures. Gas is around 14:1 and nitro is around 3:1. This will cause serious mixture issues, so bad that you will have to change at least the jets/spray barb and probably the whole carb. There will be a whole list of other issues too. What exactly are you trying to do, i.e. more details?

Changing a gas engine to glow fuel requires different carb jets, a glow plug with adapter, and removal of the spark-creating mechanism (coil, etc.), at least. There may be more. Conversion kits to do this are available, but frankly, I don't see why you would want to. Some of the advantages of gas engines are cheap fuel, super reliability, and user friendliness. You may lose all of this when you change to glow.

Thats my question, why?

Cheaper fuel, no oil everywhere, less cleanup, sounds more realistic...

i guess "to each his own" holds true...

Want to run Nitro thru it? No problem. Take 5 drops Nitro and add it to 1 gallon of gas. Stir well and go fly. Should work fine. Otherwise, buy a Nitro engine. Don't re-invent the wheel.

I have heard of converting Glow to Gas, but although it has and can be done, there is no advantage gained from converting Gas to Glow.......at all. (Power suffers, operation costs are higher and it makes people look at you funny).

agexpert,
Actually there are two. They've been around for years. In SportsCarClubofAmerica, guys have been cheating by running alcohol/nitro since SCCA began. They obviously did it for more power. Anyone could easily tell which drivers on the starting grid had done the deed as they were the ones holding the engines at high rpm before the start (because they weren't worried about cooking an engine that had the fan disconnected (another cheat)). And dragsters went to nitro for a reason. That's one.

The other benefit that can be quite helpful is on a very tightly enclosed, poorly cooled engine installation. Alcohol won't meltdown an engine like petrol can.

And the two combined is exactly why our hobby has such a preponderance of glowfuel motors and have had from the start. It was next to impossible to manufacture a gasoline hobby engine way back when. It was much simpler to create a 2cycle glow fuel one.

Ummm..not exactly....apart from diesels all other model engines were spark ignition way back when. Glow ignition was found out accidentally on a spark ignition when they were trying out methanol to see if they could get more power for speed. The problem was that the engine kept on running after the spark was turned off

From the replies, I'm sure you now understand that this is not a beginner forum question.

The engines forum might be a better place to post, and if you're wanting to run a G62 on alcohol/nitro, you will find plenty of answers from the Reno Racers.

If that's not your purpose, you might want to include full information on the engine you want to run, the type of plane, the type of flying you want to do, etc.

Good luck,

Actually, there is more energy per unit of ethanol than in the mixture we call gasoline.

My engine is a glow engine and im not sure about running gas through it but if it can I will, can you tell me if there are different ways on starting it up or about the fuel tank set up, That would be great.

Thanks, Dave Trimmer

Hello Guys, I am new to this hobby and I got some small problem. I leave in Jeddah Saudi Arabia and I am wondering where can I get Glow Fuel or how to mix it for my self. Please anybody who has an idea?[&o]. I really wanted to get some Gas powered RC but the fuel is my problem.

Dave, your last post seems to be the opposite of your first post. Is the engine glow or gas? OK, I'll flip 180 degrees. If it is a glow engine, and you want to convert to gas, you have the same problems, but in the opposite direction. You still need new jets and or an entire carb, and you'll need an ignition system, and there is no guarantee is will run well. If the engine is smaller than 1.5cu inch, I wouldn't peruse this anymore. If it is larger than 1.5cu inch, I got to ask why? Fuel costs? Why not just buy a engine designed to run pump gasoline?

As for starting and tank setup, that is often engine dependent. Why the mystery? What engine are we talking about? You're gonna get little to no useful help on this matter unless we have better details. Please tell us make and model of the engine.

2slow, that's backwards from how I understand your post. There is more energy per unit of gasoline than compared to either methanol or nitro. It is only after you take mixtures into account that methanol/nitro produces more power. Methanol/nitro will ultimately produce more power per cycle, but it only does so at mixtures much richer than gasoline, about 3 times richer depending upon blend. Gallon per gallon, gasoline has about twice the energy of a reasonable methanol/nitro blend. But the methanol/nitro blend burns about 3 times richer. Half the power but three times richer is a 50% gain. This means that methanol/nitro will produce about 50% more power per cycle in my crude example, yet gallon vs gallon, gas still has more energy. Maybe this is what you meant in you post.

Cheers.

Original Question:
Revised 2nd Question:
John W is 100% correct. You are contradicting yourself now.


Scar was 100% correct. This is not a beginner's forum question, so I'm closing this thread down. If your question is still valid and unanswered you might want to ask it in one of the engine forums.
