Future of ICE is...two-stroke!

Renault may not sell here but Nissan could use this small-diesel two-stroke for passenger cars. A clean and power-dense power per stroke engine could be suitable as future powerplants. A twin-charged (supercharger + turbocharger) 0.73 liter capable of producing 67 hp at 88 lbs! The powerband is still very narrow and emissions are getting stricter so lots of work is still in the works. Diesel-electric hybrids is the best direction.

I like two strokes and would love to drop that in my metro if they could make it throttle able.

It doesn't weigh 88lbs. It weighs 88lbs. less than their current 1.5 liter engine.

That's still light...

Stand corrected, fraction-of-a-second social media attention span.

The four-pot 1.5 L dCi/K9K is under 145kg...so that'll make it 105kg.

In the '90s Orbital was going to conquer the world with 2-stroke tech. Ummm....

2 strokes are good for range extender generators because they have less friction. Like you said, narrow powerband is a problem. 4 strokes (with turbos and whatever) win for ultimate power density because they can keep on breathing into the higher rpm ranges while 2 strokes can't.

I'm all favorable to that, some of the most efficient ICEs are 2-stroke Diesels used in ships. But it seems easier to come back with the 2-stroke layout in spark-ignited engines...
