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. :D


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

That's still light... :thumbup:

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....

Yeah, what ever happen to their other mini 4 banger?

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...
