Anyone have pics or animation of a 2 stroke.

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..

check that out. its pretty basic and involves all two stroke engines. but read that and you will know what every body is talking about.

cool pretty basic.... I imagine the powervalve just restricts flow until it opens up?

 

[WOTRider]

not really sure... somebody else can answer that much better than I. I just know to take it all apart and clean it every top-end rebuild.

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.

Not really. I would think that would confuse the guy more than anything. :nod:

If he wanted to know about diesel tug boat motors, I'm sure there is a site for that.

Moparman. Excellent animation. :cool: That's a keeper.

Moparman, that is an awesome animation. thnx for showing it

 

[Moparman1539]

No problem. Thats what im here for.

WOTRider, great article.
Moparman, great animation.
And you too, 76GMC1500

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.

What does that have to do with this thread?

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.

He wants to know how 2-strokes work.

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:
