It doesn't say anything about how it works - so i can only speculate, yes 6 stroke would be less polutive than 4 stroke, yes it would use less fuel, but i am not sure about it being more efficient. You would burn less fuel because you get 1 power stroke every 6 strokes. So less power and torque too?

It does explain it. The 5th and 6th strokes are used for injecting water to cool the chamber and therefore being able to raise compression. But to have the 5th and 6th strokes, you would have to increase RPM to not loose power...

Very interesting. Although this is not the first engine to be called a "6 stroke"!

The first was designed at the turn of the century, and had in effect two intake strokes (one drew in fresh air, with no fuel, to remove all traces of exhaust gass, then expelled it, then had another intake stroke).

The second was this: http://www.jack-brabham-engines.com/products.htm

Certainly something different.
