Me too!!! I've had 2 Daihatsu Max 360's:
360cc, 33PS and 510 kg (1100lbs?). Freakin fun to drive and surprisingly fast. Tiny. Like you wouldn't believe tiny. Made the old Austin Mini look obese.
Back ion the early 1990's I was fortunate enough to be allowed to drive a prototype Ford Fiesta fitted with an Orbital 2-stroke; the torque from such a tiny engine was amazing, you could start from standstill in any gear with no hint of stalling.
I didn't get to drive it (I was 9 or 100!), but Dad took me to a Mercury Marine international conference in Australia, and they had a BMW 320i with a 2.0 6 cylinder orbital 2 stroke. It was part of Mercury's development of their direct injection 2 strokes at the time. Sounded awesome.
I'm a bit surprised that two-stroke engines haven't made more of a come-back. With direct injection, the problem of blowing un-burned fuel out of the exhaust (which is what caused most of their inefficiency and excessive emissions) should be solvable.
I have wondered this too. I suspect it comes from the loss of "valve" timing... but what's to stop a poppet valve 2 stroke with supercharger and an oil pressure fed bottome end? Basically a modern 4 stroke without the wasted strokes
You can adjust with valve timing, have 2x the power strokes, direct injection to reduce the hydrocarbons, supercharger cylinder purge and still sound awesome
Plus the aftermarket crowd would have some fun with the open exhaust ports, supercharger-purging flow and opening the injectors late then an extra spark... You could probably blow the exhaust clean off!
