Inside the cylinder of a running internal combustion engine

submitted by SFOGuy

9 years 4 months 4 weeks ago

This is pretty cool; to my recollection, a diamond window set into the cylinder wall lets you shoot a internal combustion engine at work---You can see the intake cycle, the closing of the valve once the gas and air have entered, the movement of the piston upward (and compression of the gas/air mixture), the spark plug, the spreading wave front, the movement of the piston downward, and the opening of the exhaust valve to push the combustion products out so that the cylinder is emptied and ready to suck a new supply of gas and air to do it all again. They don't show the full exhaust cycle in the film loop...

I imagine it lets engineers optimize cylinder heads (e.g. Dodge "Hemi"), timing cycles for opening/closing, look for ways to encourage a more complete burn (emissions), etc...
