New Rotary Engine ????

[Illini85]

I just found the website for a UK company called Advanced Innovative Engineering that has been working on single rotor Wankel style engines for autonomous craft applications. Harking back to Norton Motorcycle's design for a rotary engine they seem to have focused their efforts on cooling the rotor and reducing oil consumption. I found interesting their largest engine reportedly is 120 hp (at 8,000 rpm) single rotor, water cooled, fuel injected, dual plug, FADEC controlled, design that has a core weight of 62 lbs. Don't know if any of these are running outside of the lab yet or not. They have named a distributor for the US market.

So for what it is worth here it is.

Fuel consumption is listed as "0.51 - 0.57 lb/bhp/hr". So for 120 bhp that's about 65 lbs/hr, or nearly eleven US gallons per hour?? Have I got that right?
It seems to burn its own weight in fuel in just one hour.

At full power I wouldn't doubt it. Fuel efficiency has never been the domain of rotary engines but one would think the injection and FADEC would help.

Well, it's much better than the widely used Rotax 582 (0,699 lb/hp-hr)...

Wankels were always thirsty...
