I'm curious if this actually ends up being significantly lighter though.
I doubt it'll end up replacing a conventional two stroke motorcycle, as it's far more complex. But I could see it used in aircraft.
People will go to some great lengths for a little extra performance. Think of the Wankel engine, it works, but this is basically the same sort of power/weight improvement and it's immensely less complicated and more practical with this 2 stroke engine. But that crazy Wankel engine has actually gone into mass production in a few cases, notably in the much loved Mazda RX-7.
And let me be clear, this 2 stroke is far more practical than the rotary Wankel engine.
And yeah, I agree. I don't see this replacing most existing two stroke engines, a cheap simple engine is generally cheap and simple for a reason, price and complexity are usually the greatest factors in those cases. It's the existing 4 stroke engines that need to watch out, those are the engines that this is a clear upgrade from. I mean if you look at any car with a turbo charger, it would be better off with this engine, with either more horsepower or less weight.
