it seams that you can "just about" run these things on anything

Watch at YouTube

?t=75

same engine as above, but a different video

Watch at YouTube

?t=87

WD 40

I would like to try this out on a helicopter glow motor. What kind of power do you get? Are there any changes to make it run?

Not too surprising as these are basically two stroke diesel engines.

Hmm... Not really. Ignition in our engine is the result of a catalytic reaction between the glow plug element and a hydrocarbon. In most cases that hydrocarbon is methanol but other hydrocarbons will also work. We have two stroke glow engines.

Diesel is compression ignition. At some point compression will be high enough to initiate combustion without a glow plug. That is diesel ignition. There is a difference in how our glow engines operate and diesels.

Yes, WD-40 will both glow and diesel in our engines.

It was probably 40 years ago. I was putting my Rossi .15 control line engine away for a period of time (no carburetor or muffler). I had installed a prop so that I could work some WD-40 through the engine for corrosion protection. It was just the engine - no airplane.

Without giving it much thought, I sprayed a healthy blast of WD-40 in the exhaust and intake and began working it through the motor. At some point I began flipping the prop to work out the excess oil. Much to my surprise and horror, it started! I was now standing in the middle of my bedroom with a Rossi .15 in my hand roaring WFO! I didn't know what to do. In an instant I considered throwing it. I considered holding it. I wondered, if I choose to hold it, how hot will it get.

In the end I choose to hold the engine and it ran 5 or 10 seconds before running out of fuel. My dad came in the smoke filled room with a look on his face that said don't do that any more. I must have still had a look of terror because he didn't say anything at all.

LMAO.....classic.....

A tiger by the tail.....love it.

Reminds me of those vids of the guy throwing a running Cox .049 with a rag hanging off the back end....to see how far it would go....

They sell diesel conversions for glow engines. Just a head i believe.

The memories of my Rossi starting with WD-40 made me a little nostalgic. I still have that engine and in fact still have the prop that was on it that day. It was a Kelly 7x6 cut to 6x6. Because it is raining today, I ran upstairs to find it.

I had been running the engine on a Goodyear (Scale) control line model. Back then the pipe of choice was a megaphone pipe. They gave a nice performance improvement and restarted better than a full pipe. It was also so loud you could literally hear it for miles.

I have two Rossi .15 from back in the day. One is NIB with glow plug head conversion, head shims and R/C carb. The other was my runner.

Some random pictures....

I suppose this really should be in the "Engine Lovers Thread".

They do sell diesel conversions. Most are by Davis Diesel Development but there are others. I have experimented with DDD heads with mixed results.

They also sell model engines that are diesels as they come from the factory. It is important to note that these are true compression ignition engines.

Most of our model engines are glow ignition. I know it sounds like semantics but it is an important distinction. It is important to note model glow and diesel engine use wildly different fuels.

This a video I made a few years ago.

Thanks for the video, always wondered if diesel was harder to flip the prop due to compression, but not so bad as your vis showed.
Any idea what the compression ratio is ?

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

My internet is messed up right now so i couldn't watch the video. How does the Diesel run in comparison to the Glow version? Does it have more power?

GyroFreak... Sorry it took so long to get back to this thread.

The short answer to your question is- I don't know the compression ratio. Compression ratio is always a little tough to quote in a two stroke. After all, there are holes in the cylinder right?!?

In a model Diesel engine the compression ratio is adjustable from nearly nothing to extreme. But more than it being adjustable, it nearly impossible to gain access to the combustion chamber of an assemble engine. Measuring the sweep volume of the piston is simple enough. Measuring the volume above the piston at TDC is functionally impossible.

The best I could say is that it is somewhat more than a conventional glow motor but not as much as you'd think. The ether in the fuel doesn't take much compression to ignite.

Wouldn't the mechanical drawing/specs provide this info....or at least the dimensions to calculate it?
