Re: High Schoolers Reduce 2-Stroke Emissions by 40

"You must not follow 2 stroke advances much?

Modern 2 strokes have both exhaust valves and direct injection. Meaning they do in fact burn their fuel almost completely."

Uh last i checked 2 strokes dont have valves they had reeds........ and no the dont burn almost all there fuel cause if they did we wouldn't have oil and gas build up in and around our exhaust on mopeds and other 2 strokes.

Oil is not fuel .. and yes, most of the fuel is burned.

Re: High Schoolers Reduce 2-Stroke Emissions by 40

You'd have to look at the Evinrude E-Tech. It might have exhaust valves. It seems that some oddball arrangements have had them in the past, I swear some Soviet Block 2stroke car had rotary exhaust valves, maybe the Trabant?

Re: High Schoolers Reduce 2-Stroke Emissions by 40

You can have a 2 stroke with regular poppet valves, they're often used in large 2 strokes.

no groms no blasters /

Let's not forget the mighty diesel 2-strokes that power locomotives and ships.

I mean, they're completely unrelated to the topic at hand, but are awesome.

how about people stop using cheap shitty oil that smells and makes a smoke screen behind them

If the smell bothers you, kit it, and move to the front. 20:1-4-Life. jk

But the smoke trail adds to the "Aww, look at that junky old moped" cuteness of my beater maxi.

Re: High Schoolers Reduce 2-Stroke Emissions by 40

damn

if i knew tuned pipes were good for the environment, i'd have stopped using them a long time ago.

Re: High Schoolers Reduce 2-Stroke Emissions by 40

I find the smoke screen helps me identify exhaust leaks. :)

Mix it 60/1. Jim

Re: High Schoolers Reduce 2-Stroke Emissions by 40

there a lot of new advances in 2-stroke technology that are making them more environmentally friendly, 2-strokes arn't dead yet. check out:

-the aprilia di-tech

-and the ricardo 2/4 stroke engine (shows how 2-strokes might be useful in the future)

Re: High Schoolers Reduce 2-Stroke Emissions by 40

yes expansion pipes lower emissions, increase fuel economy, and greatly increase power. every 2 stroke should have one.
