this is real hot: small rotary engine - Aixro XR50 Wankel

Hey,

This engine would fit on a bike, it looks small to me, .....and it has 50hp..........that's maybe a little to much for my bike .....

..........I think this is for the real bikeracer heroes............

Did they ever resolve the problem of wear on the ceramic seals on the rotors? As I recall, that's what killed them for use in cars.

Basic engine selling price $5150.00 It sure does look to be a really neat engine though. Going to the site shown above there is a video and you get to see the motor mounted in a Kart and although small the engine is a bit larger that it seems when looking at it standing alone.

The seals and emissions of Wankels were always their weak points, but the "Renesis" in the current RX8 gets pretty good reviews.

Seals haven't been an issue for years. The main issue with rotary engine is emissions and thermodynamic ineffiicency due to larger combustion surface area for a given displacement (cubic inches) than a piston engine <---- more surface area for heat to dissipate from.

OH, almost forgot: seals are only an issue if engine is overheated, run too lean, or oil injection system fails. I have almost 200,000 miles on rotary powered vehicles (mainly 2nd generation 13Bs) and haven't had an engine failure yet.

hahaha...sorry for the off topic post...sorta.

back in the 70's, I had a chevy luv pick-up. good gas mileage...but a total dog. my brother in law had a mazda p/u. we had borrowed his p/u for some reason, & my X-wife was driving. we were going down 71 south...(4 lane) & I asked her what was her hurry. she said she was only going 40mph....she was going 4 grand on the tach!!!! I believe we were doing 90mph.....what a ride!!

I now return you to your thread

do ya think they could make a way smaller wankel for our bikes??
