Six Stroke Engine

[Gig_em]

Not Harley related, but pretty cool.

From the article:
It runs like a conventional four-stroke combustion engine through each of the typical up-and-down movements of the piston (intake, compression, power or combustion, exhaust). But just as the engine finishes its fourth stroke, water squirts into the cylinder, hitting surfaces as hot as 1,500°F. The water immediately evaporates into steam, generating a 1,600-fold expansion in volume and driving the piston down to create an additional power stroke. The upward sixth stroke exhausts the steam to a condenser, where it is recycled into injection water.

Wow - dems some smart fuckers. That a pretty good idea.

No only saving gas, but also helping cool down the engine and cleaning her up a bit too.

I wonder though, if you let the engine sit a bit in the middle of the 5th stroke, how long it would take for rust to build up? And I wonder how much liquid gets into the oil?

Pretty neat idea they came up with.

Pretty slick, and only a one banger to boot. Wonder if it could be adapted to a twin cam application...Mmmmm.
