That's interesting, I wasn't aware they get injected separately. While this would decrease VOC emission greatly, I can still see these engine designs being higher emission than a comparable four stroke although I may be wrong. I'm not a mechanical engineer.

My reasoning is that oil still gets burned, likely at a higher rate than any oil that gets through on the four stroke. It would be interesting to see if two strokes could be redesigned to place the oil outside of the combustion chamber, I think that would be a serious game changer for ICEs.

That being said, I'm definitely an advocate for moving away from combustion altogether.
