Interesting v twin 2 stroke design

[Woodpecker]

Found this 2 stroke engine designed by Basil (who the he11 names their kid Basil) van Rooyan pretty interesting. Looks like he's using a power valve in place of reeds. Probably too bulky to ever be used in a chainsaw, but nice to see someone trying to keep the 2 strokes alive.

Interesting article. If his design has eliminated roller bearings, then he must be using four-stroke style main bearings in conjunction with the high-pressure oiling system.

That's what I thought too Jacob. Makes sense using the 800 v twin 4 stroke crank off a Suzuki. Gota give the guy credit for Frankensteining it together. Although, judging by the vid, it doesn't look like its fully functional yet.

Kawasaki has something cooking too.

That's just as cool Wayne! The cross plane crank and power poppet valves make it similar to a 2 stroke diesel but it's being run on gasoline.

I've thought of some different designs like a super charger, with an intake poppet valve and several little exhaust ports around the bottom of the cylinder like a reverse Detroit.

Also I had given some thought to a cylinder ported rotating sleeve 2 stroke. Normally a rotating sleeve engine is a 4 stroke with a rotary valve on top.

Not like my ideas are particularly special, just more unique-ish designs.
