Flyinfool Posted January 9, 2013 #1 Posted January 9, 2013 Incredible piece of engineering. OPERATIONAL THERE ARE STILL SOME REAL ENGINEERS IN THE WORLD. THIS IS AMAZING..... Watch it all the way through, he machines, assembles and runs this little engine..... This is not CNC technology; this guy made everything at home on his lathe and drill press. Took 1220 hours (a year and a half?) to make the 261 pieces. Note the end-loaded crankshaft into the block (like an Offy), 12 individual cylinder heads, TINY rods and pistons, dual "underhead" cams with pushrods to rockers in the heads. And, he did break-in runs using an electric drill driving the crankshaft! Even if you're not an engineer, you'll appreciate this! http://www.wimp.com/tiniestengine/
BigLenny Posted January 9, 2013 #2 Posted January 9, 2013 You're right! I'm not an engineer, and that is freakin amazing! Man, I wish was that smart!
bongobobny Posted January 9, 2013 #4 Posted January 9, 2013 I'd like to know a little more about his ignition system and just how is he regulating the rpm, it seems to be fixed...
Condor Posted January 9, 2013 #5 Posted January 9, 2013 Impressive, but all I could think of was why didn't he use hex cap screws instead of the slotteds and a few phillips???
Gary N. Posted January 9, 2013 #6 Posted January 9, 2013 I'd like to know a little more about his ignition system and just how is he regulating the rpm, it seems to be fixed... Bob, diesels don't need an ignition system only compression. To regulate the speed would be done by fuel flow.
cecdoo Posted January 9, 2013 #7 Posted January 9, 2013 Amazing to have the skills and patience to build something like that. Wish I had both:clap2: Craig
playboy Posted January 9, 2013 #8 Posted January 9, 2013 That was Impressive thanks Jeff. I would imagine he machined all of his bolts making cap bolts would have probably added several more hours. Notice how everything was torqued properly. Sorry Bob no spark plugs here probably won't need any Seafoam either.
Flyinfool Posted January 9, 2013 Author #9 Posted January 9, 2013 Some of my observations. There is no lubrication system, it just uses the oil and grease applied during assembly. There were no actual bearings on the journals, so I am not sure just how many times he will be able to run it. It says that the only machines he had were a lathe and a drill press. I wonder if the drill press was lost in the translation and it was really a milling machine. Many modern diesels have glow plugs to help get them started. I did not see any sign of glow plugs on this engine. Any way you look at it, it is/was a labor of love and should be very proud of his accomplishment.
WildBill1 Posted January 9, 2013 #10 Posted January 9, 2013 Very nice model although its running on air instead of diesel, still alot of precision work involved.
barend Posted January 9, 2013 #11 Posted January 9, 2013 I've seen this before, still amazing. Now if only my video would play without me having to move the cursor on and off the screen to advance the pic.
