For some, learning by example is the best way to get info sealed into the noggin. If engines are the thing they want to learn about, then Matt Keveny's site, Animated Engines, should be the first stop.

Unlike the engines profiled, the site couldn't be simpler: clicking one of the 21 different engine types will take you to a page demonstrating how that engine creates power. The animations can be run anywhere from one to 25 frames per second to provide a crystalline breakdown of an engine's combustive ballet.

There's even knowledge for the engine expert, with animations detailing some forgotten freaskshows of the pistoned world, including the Unknown Beam, Low Differential Stirling and Crank Substitute. Head on over to check out some line-drawing gearhead pr0n.

      To really put into perspective how amazing engines are...the Four Stroke's crank completes about 64 revolutions in 30 seconds. That comes out to 128 rpm. Far slower than any passenger car idles. So as fast as that animation is, it's still about 8 times slower than an actual engine at idle...i think. In any case, engines are amazing. To prepare a chamber for a cumbustion, then evacuate the waste and prepare it again that fast and over and over...

      Well, I can what I'll be doing the rest of the day.

      Everyone should learn this in shop class or physics in grade school.

        Obviously you didn't bother going to the site. There were in fact 21 engines there. It was an amazing visual to see all of the different ways very smart people have accomplished the same thing. Too bad you missed it.

      Poor guy is probably trying to show all his friends his new site that he's so proud of, and Autoblog has to go and redirect so much traffic that it barely works. Lol.

      I really don't like how the depict a diesel being so much different than a gas four stroke. Replace the spark plug with an injector, and increase the compression 2x and you have a diesel. Why the need to unnecessarily complicate it?

        Also, why make the four stoke a pushrod motor? When most, cept for GM V-8s, are all OHC now?
