See how a carburetor works–in slow motion | Video

Whether or not you understand how a carburetor works (hint: Google “Venturi effect”), it’s intriguing to watch one operate in slow motion–as evident in this video.

We’ll let you decide if this is a valuable teaching aid or a perfect time killer. Or maybe both.

Some beautiful slow-motion shots in here. Plus way cool to watch a carburetor in action where you can see everything.

I couldn't help but notice the varying droplet size, which is the carb's Achilles heel.  I also saw some fuel falling out of suspension along the walls and floor of the "intake."  Amazing how just seeing something you've only read about (or saw evidence of after the fact) leads to greater understanding.  Now it's time for a clear combustion chamber to watch the flame front and also seeing the effects of scavenging when it's worked out correctly.

The company I work for (AVL, an Austrian automotive engineering and test systems company) sells a single cylinder research engine which can have a clear quartz cylinder for exactly that purpose. We also make a video system for looking at that in normal engines (requires an additional access hole in the head.) It's pretty amazing stuff.
