Found this 0.1CC Micro Diesel engine

[Novian]

Looks interesting. Would be cool to get some plans for this or one similar.

Has a pretty cool spring starter too!

and it's invisable ;D

sorry cannot see the picture

That's better,nice engine what are you going to put it in radio gear is so light these days it would make it practical to use RC.

I'd probably just keep it as a running display model like the creator has it in the video.

Their where some plans for a NANO 0.1cc Compression Ignition Engine in Model Engineer a few years back.
Specifications
Bore 5mm
Stroke 5mm
Capacity 0.1cc
Height 32mm
Length 38mm
Max Speed 40k rpm

I have the plans somewhere so I will dig the out

Years ago I did this one,
Nano, a 0.10 cm3 "diesel engine", by Richard. Gordon, in a pullout supplement in Model Engineer, vol 169, p 566 N°3932. could be pulled out from copy you may find. A poor runner in my hands, and too light for a paperweight but of course not not a clue for a poor design !
I cannot find fuel for this type of engine, moreover the noise (wow really hudge for a so tiny engine) makes tests and experiments difficult (neighboors dont agree).

Nice little engine and the sound alone brings back memories. As a kid, a few buddies and I were into control like airplanes and after school would head out to the school yard (would probably get arrested for that today) and fly out little planes...mostly .049 1/2A size. You could always tell when you had it leaned out properly by that high pitches scream of the engine. Of course back then, you could also buy a brand new Cox Baby Bee .049 engine for $5.95 as I recall. Those were the days....not I'll have that sound in my head all day :big:

I asked the video poster if he had plans for the engine, and he told me what to Google search:

I found this first link at top: http://modelenginenews.org/nano/index.html

Supposedly the plans are from Model Engineer Issue #3832

That's my video. Flying season will be here soon and I haven't built an airplane for that engine. I did decide on a model though.

Nice little engine. What are you using for fuel?

 

[mu38&Bg#]

I still have some old cans of Eric Clutton's fuel. Davis 1/2A blend should also work.

 

[Blackdavid]

Sorry if I rise the thread from the dust, but are any plans available to a 17yo student? I want to build something small like this as my first engine..

 

[rklopp]

You can buy the Gordon Nano plans from a model engines plans service in the UK, I forgot which. The copies they send are kind of xeroxes of faxes quality, almost.

I strongly recommend against building these as a first engine! They are not easy - I've built three, and it took a lot of fiddling to get them going. I had at least a half dozen prior, larger engines under my belt before attempting them. Kudos to you if you can pull it off, especially as a first engine!

I find the engines also wear rather quickly, for reasons that remain mysterious to me.

 

[BaronJ]

That little engine is a real rip snorter. I bet if you get a rap on the knuckles from the prop you don't do it twice

This is true, the small engines is difficult to make tight against leakage and loss of compression.

I would reccomend the 2.5 cc engine or larger as a basis to begin to learn to machine and produce parts that should be simple and easy to make the parts in a model engine.

 

[Blackdavid]

Im afraid that bigger engines may give me problems as they are more complicated, and plans with metric units are often too expensive, and the free ones non existing, and Imperial numeric system is too complicated for us europeans to understand.. As I am just finishing school this year, I don't think I have enough practice on the lathes and mills to build one. And materials are a problem too..

Bigger engines are probably easier to make ! I certainly would be more inclined to tackle one a lot bigger than the Nano. As far as metric is concerned, as long as you get the decimal point in the right place, counting in tens is more convenient than eighths or sixteenths. In any case most digital measuring devices will do the calculations between imperial and metric at the press of a button.

Anyway there really are only two numbers to remember 25.4mm = 1 inch and 39.3 thousands of an inch = 1mm. Given the scale that most models are built to, using these two numbers will suffice.

On you last point if you don't attempt to do something, you won't get much practice ! Someone once said to me "If you aim for nothing, you will hit it with marked consistency !

I agree, i was taught that size is proportional to cost/difficulty.BUT THIS WORKS BOTH WAYS
You may find for example that 2.5cc is ideal.Going larger will be more expensive but no easier
while going smaller will not be cheaper but will be greatly more difficult.Get the plans,choose the scale
Metric or imperial makes no difference.I find metric easier but for tight tolerances i usually work
in thous.I can see and feel a thou and with modern digital mikes and calipers its easy
As an apprentice we were taught to file and measure with a steel rule to +/- 5 thou. Not difficult
My eyes could not do it now But 5 thou was 1/3 of 1/64 on the rule or a line width.Try it you will be surprised

 

[Blackdavid]

Thats what I don't understand. Its easy to convert for example 1 inch to one millimeter, but i don't understand that 1/3, 1/64, 1/32 etc. things..

SO i would probably fail with imperial plans..

Imperial inch is not difficult, it is fractions such as 1/64, 1/2 etc , it means how many parts is it in the whole 1 inch. Let us say the measure is 3/4, it means 3 parts of the whole 1 inch or in decimal 0,75 inch. The formula: 3/4 = 3 x 25.4 : 4 = 19,05 millimetre
