Besides the Ilmore, Ecomotor has some fascinating ideas!!!
I have long been intrigued by the opposed piston layout; this is a potentially vast improvement on that.
Their clutched engine module idea is something I've long wanted to see as well.
Electric Turbo? I sure wouldn't have thought the electric part compatible with turbo rpm range... but they think it is? Hmmm. Cool if it works.
I understand the Ilmore concept but don't have any intuition about how that could work well... the operation of that expansion cylinder confuses me.
