first we got the fantastic Twin charger engine from VW.

then the VCM from Honda,

now we got this. and look at the figures.

300nm at 1000 rpm. very very driveable. in fact,if left in D alone, i think the car will fly. lol.

i want i want i want.

anything that reduces fuel consumption, engine capacity and gives more power is good.

less is more!

The 2-stroke is used under partial load and LOW rpm condition. 4-stroke is used when full power or high rpm is used.
The low rpm and high torque suggest the use or high pressure force induction. Then I wonder how they manage to rev the engine? probably it does not rev as high as a NA engine.

Whatever it is, 27% fuel saving is fantastic.

I wish more car companies will come up with these new engine concepts…AND put them into production.

One good engine that never caught on was the supercharged Miller Cycle engine in the Mazda Millenia. ITs such a nice engine. In concept this is closer, not so much for making power but to reduce pumping losses inherent in 4 stroke designs

Its good we have this vs. the diesotto concept. It will be an interesting next 10 years.

I wonder how it would pass emisions standards as 2 stroke engines typically (and I’m not talking about the smokey kapchais) have large intake/valve overlap (similar to the older rotaries). Which is why they need a positive displacement intake (supercharger or turbo) to force air in during exhaust/intake stroke and direct injection.

Of course you make more power. 2 stroke motors make 2x more combustion burns per given rpm. A prime benefit of 2 strokes will be having less pumping losses. You’d probably noticed 2 strokes have very little engine braking.

Interesting.
