Well I am pretty new to this 2 stroke stuff. I understand the basic concept, but wondering how the valves come into play ect... I come from building v8's and cars in general. anyway. Would like to see some kind of pics or animation of a 2 stroke in action..
2 exhaust port power valves like Honda's HPP and RC vary the port timing and area, also changing the dynamic compression ratio. 3 port systems like what everybody else uses do some things to alter the harmonics of the pipe and may or may not also vary port timing/area.
I Guess it wasn't good enough. But, on a continuation of the previous post, the underpiston supercharging is the reason 2-stroke gas engines burn their oil. Not all 2-strokes burn their oil, but the with underpiston supercharging, the airflow through the crankcase makes it impossible to try to maintain a conventional lubrication system with a sump.

It's not that it wasn't good enough, it didn't relate to the question. The guy was asking how a powervalve worked, not a poppet type of valve and a turbo.
Completely different animal and only adds confusion to the thread.
Seeing as how this is a dirtbike site, one would take it for granted he wants to know how a two-stroke dirt bike engine and powervalve works. But, hey, what the hell do I know? :coocoo:
