The rotary in the article is a 2 stroke design, by my understanding. Fuel injected 2 strokes have been around for years now. In saws, the Stihl 500i. Scaled 2 stroke engines, both with and without fuel injection, have also been around some time. The KTM 300 XC is a very modern example with 300cc displacement, so the same general category as the one in the article. Modern outboards on boats go even bigger. Yes there’s a push on at the moment to retire the fleet of small 2 stroke engines in older garden power tools. Emissions controls have been tightening up on new tools over the years. Electric tools are rapidly displacing them with lower maintenance requirements and less noise. There’s a lot more to 2 stroke engine development than just saws and lawnmowers from the 80s, though.
