Amazing work! Proof that there is no such thing as too much leisure time.
Music is distracting though...
Is it really an engine or is it just turned by compressed air?
Perhaps it's a diesel of some sort?
I don't see much in the way of mixture control, (injection) or ignition.
I probably missed something.
I love it when people turn to creativity in boredom, as opposed to just constantly spilling their political (or religious) guts all over the Internet. This guy - the tiny engine builder guy - THIS GUY is inspiring.
It has an air filter and manifolds, and I think the devices at the front are coolant pumps and a coolant tank (google translation). Not sure how the system is supposed to actually work though.
Lubrication is by the old "drops from an oil can occasionally" method I think.
I don't think it's actually an engine but it still earns 4 stars from me.
I'd like to be wrong but it really doesn't matter that much.
