I came across this video on Youtube showing the death of the 2 stroke engine is greatly exaggerated. Athena, an Italian powersports engine aftermarket parts company shows off their own direct injection system for aftermarket cylinders. The video makes some impressive claims. I think a 4-stroke versus 2-stroke smackdown needs to occur, pitting Hondas 50cc FI scooter engine against this Athena tech.
We’ve seen DI systems from Orbital and subsequently Aprilia, Piaggio and Evinrude in the past. But coming from Athena suggests this could be in place for retrofitting and maybe turning a 5% oil burning piston-ported 150 two stroke generating a mind blowing 5 HP into something clean, efficient and still not ‘stroke-wasting’.
