The latest injection 2-stroke tech is very good.
My boat outboard, a 225HP V6 2-Stroke Mercury Optimax, injects fuel into a separate 'Holding Chamber' before mixing it with high pressure air and injecting it into the combustion Chamber.
Obviously it's complicated, and you have a very high pressure air compressor hanging off the engine as well as a fuel pump etc.
But my engine is over 10yrs old, and meets the California emissions standards for Outboards, beating most of the 4 stroke competition.
I've been waiting for other applications to adopt it.
