Years ago when Mazda used the Wankel rotary in the RX7 I have been aware at how good the technology was. For some reason people didn't embrace it. I think there were small issues back then.
Looks like it's making a come back.
I read an article the other night about the rotary gaining popularity again. Possible use in a snowmobile! A company called Freedom Motors has been improving the designs and building them for various applications.
Direct injection
Lighter weight and smaller size to other engines of comparable HP
Really low emmissions and fuel consumption
Lower manufacturing and maintenance costs than a 2 stroke
Almost vibration free
Much lower sound levels than 2 stroke
Check out their website. Rotapower is the one used for recreational vehicles. Look at the applications section. Jet ski, jet boat and generator caught my attention. Amazing how small and lightweight they can make them and produce big power. All with much lower fuel consumption, emissions, vibration and noise. Lower maintenance!
"•Superior Emissions Performance - Recent tests verified by CARB that the Rotapower engine operating with gasoline produces less than 1% of the emissions of a comparable two-stroke and 14% of those for the four-stroke piston engine. The Rotapower engine uses a fuel delivery approach that eliminates the highly carcinogenic particulates produced by direct fuel injected diesel engines and new lower emissions two-stroke engines.
•Outstanding Compact Power Delivery - Power to weight ratio for the Rotapower engine is 75% better than two-stroke engines, 250% better than four-stroke piston gasoline engines and 600% better than diesel engines. It has been operated successfully on gasoline, kerosene, alcohol, diesel and natural gas. With only two moving parts, cost and maintenance are projected at well below four stroke piston engines."
Would make an awesome generator for sure..........future snowmobile engine??!! Rumour has it.............
