Video: Why Yes, You Can Turn an a/c Compressor Into a Working Engine

https://www.youtube.com/embed/SxqyfB83tSo

In theory, all you need to make a functioning engine is fuel, air and spark.

So, maybe it shouldn't be much of a surprise that an old air conditioning compressor from a car can be turned into a working three-cylinder engine with a few modifications.

I've been a massive fan of "Lets Learn Something" since I found them a few months ago; there's a different episode where they show off their literal PILE of carburetors and all the wacky workarounds they have to different problems. Modifying a broken air compressor into a V-twin, OHC 2 stroke is also up there in crazy. Can't wait to see what they come up with when they get some capital.

Well I learned a lot about air compressors, I was only vaguely aware that there was some reciprocating compressor mechanism in there.

Holy crap that was way more work than I anticipated. I'd have given up & bought a predator long before I got that running. 

Super cool. Thanks for sharing that, Colin.

Old school aircraft mechanics that were sent to remote locations often had a written set of instructions on how to convert a flathead Ford V8 into a functioning 4 cylinder air compressor. (4 cylinder gas engine)

i have never found a copy, but imagine it would make good reading, in a gear head sort of way.

make do with what ya got.

Huge work, but think of the amazing pit bike you would have with this powering it!
