I know this is a bike forum but I'm sure someone will be able to answer my question.

Right well Nitro cars use glow plugs and compression ignition like a diesel engine so if I used diesel in my nitro R/C car would it run?
I ask as diesel is a lot cheaper than nitro fuel and I think it would be quite interesting to see if it works.

the nitro fuel is a lot more volatile than diesel and also diesel engines have much higher compression than nitro cars.

I have thought about doing this inthe past. I have never done it though.

I recon you will be able to get it to work but it will clog up pretty quickly.

nitro also lubricates the engine like a 2 stroke engine, and seeing as deisel doesn't then it might overheat and seize.

you might be able to dilute diesel with nitro maybe 50/50 but imo I wouldn't risk it seeing as I payed 350 squid for my car.

My car was only £120 and it's sat in my garage for 6 months collecting dust ontop of the fridge.

I could do a mixture of 2 stroke oil and diesel as I have some 2 stroke oil aswell. Then it's getting lubed aswell.

I would have thought that diesel was quite oiley though.

I very much doubt it would work.
Diesel would require a much higher temp to burn, i doubt it would get hot enough under the low compression of the rc engine.

No, no way, no how, not a chance, won't work.....ever.....nada.

Get the idea?

A diesel model engine does not use anything like diesel fuel.

It's not gonna work. Diesel requires a much higher compression ratio to ignite. You can get small capacity r/c diesel engine though, I've seen them somewhere, maybe Antics in Cardiff.

Just found some here which are very similar to the car engines. You can apparently get diesel conversion heads for your current engine.

Diesel model engines are popular on boats and also some big planes. For some reason they're not popular with cars. But I can't see the point anyhow - the 'diesel' they run on isn't normal derv you get from Esso, it's probably the same price as the 25% nitro stuff you stick in now anyway. Thumbs Up

Sorry but I think I will keep it, it's still fun revving the nuts off it.
Have a look here www.nitrotek.co.uk It's where I got mine from and they do a really good basic model.
I read a review and it got a good right up and I can tell you that it's a good car.
Nitrotek have excellent service aswell and are always happy to help.

Not related, But I had 30% nitro which I stuck in my buzz board, It went SO much faster it was unreal.
It easily added 50% of the performance it had on normal 2t premix. I ran it on 30% nitro for months and it didn't seize as people had suggested it would.

there isnt really any such thing as a nitro engine as such its just a nickname as a lot of these engines dont need or use any nitromethane at all they actually run on a mix of methanol & use either a synthetic or castor oil for lubrication the nitro is added to give it a bit more power and it helps to stabalise the tickover and improve the throttling

the diesels are not DIESEL again a nickname they actually run on a mix of ether and oil

and you wont get either of them to run on diesel

My brother put it into his Tomos moped and melted the plug. We had to unbolt the cylinder head to get it out. It did go really well but only for half a mile or so.

Agreed - Nitromethane is used in small ratios sometimes but the word "Nitro" has been adopted as a marketing ploy.

it would destroy a nitro engine. I have a HPI savage 21 and it requires 20% nitro fuel anything else and refuses to start.

Actually the glow-plug engine isn't strictly comression-ignition like a true diesel. It relies on the heat from the glowing plug filament to ignite the fuel initially then the heat from combustion keeps the filament glowing (this is why a blown plug will keep the engine running but not re-start it again.

The ignition timing is reliant on factors such af fuel combustability and compression ratio, so it's kinda half-way between a spark-ignition engine and a compression-ignition engine.

Never thought of that before. You learn something new everyday Karma

totaly off topic but could you make a 2 stroke diesel? there must be some advantages to it, not that i could think of any...

That's what I thought and that's why I thought it could be used as a replacement for nitro fuel. From what people have been saying on here I guess not.
