Title: Watch this handheld-sized diesel being made and operating
Post by: Wrenchmensch on August 09, 2012, 01:46:33 PM
Hi Guys,

This video is amazing. It details the fabrication, assembly, and operation of a tiny V-12 diesel engine.

I don't,think that you could call it a Diesel, as it looks to me to be running off air pressure.
And the cam gearing shows me it is a 2 cycle.

None the less it is an amazing piece of craftsmanship.

I share the link on another forum I participate in but did omit the diesel part within the title as I have to agree. Looks like a fuel line but now that you mention it air would be the simpler answer and prob. more accurate since I dont see a source of ignition

There is a lower limit to how small you can make one of those and have it work. The volume of air in the cylinder decreases with decreasing size faster than the area of the cold metal cylinder walls, untill you reach a point where it becomes impossible for the air to contain enough heat to overcome the cooling effect of the surrounding cold metal...

I seem to remember the limit is around an inch or so diameter, but it's been a while, and it depends on other assumptions (like speed)

It is a very nice model tho (I am also susceptable to small working steam engine envy ;P)

I agree it prolly isn't running on fuel but never the less it is a high quality model. I challenge any one here to duplicate a 1200 hour + project of equal complexity and quality, certainly not me I wouldn't spend 1200 hours on any project.  ****  No insults intended --

the project just deserves respect as it stands as others have mentioned.
