Future of 2-strokes. Not dead yet?
Have any of you looked at the clean 2 stroke motor. It has an oil bath and burns half the hydrocarbons. Could this be the future of 2 strokes? Or do you think that this was too little too late.
Heres a link to an article.

I don't see where it's a big improvement. You are still relying on ports and the incoming charge to clear the cylinder of burn't gases which means a lot of unburned fuel going out the exhust port=not real clean. Secondly, I can see all kinds of issues with that flexible membrane.

no oil injection....much cleaner, your not dumping that pint of oil every time you fill up

there are some 2 strokes that burn as clean as 4 strokes and are just as efficient.one example is the E-TEC by Evinrude they do not smoke very much if any.

Great Post J-Dog
The idea sure merits research. I agree with Vodoo on the membrane it looks like a real tricky balance there but nothing that could not be solved with good engineering. The amount of unburned fuel can be dealt with a proper tuned pipe it would be very clean with all the paramaters dialed in. My hats off to Mr Koeppel for thinking outside the box!!

I would think that pwc manufactures would be intrested in this idea concidering the cost of building 2strokes vs 4strokes is a major jump.
A small design change and they could build the same 2strokes they have been building and meet all the epa requirements. Saveing money and helping the enviroment..........win-win

The solution is already here in the GM 2 stroke diesel. It uses fuel injection and a blower and has an oil bath. It is the most efficient diesel on the market today
