First of all, sorry by my english. That's not my native language.
I was reading some texts about the wankel engine, and I suppose 
that may occurs problems with  deposits of carbon due the fuel used.

If you could see an alcool engine opened after 200.000 km. There 
is no carbon deposits and the motor is so clean, that seems that 
never was turned on. Besides, the alcohol engines are 10 per cent 
more potents than the gasolines ones, with the same model of engine.

So. I was thinking if it was possible to use alcohol instead of gasoline 
in wankel motors. No more deposits of carbon and more hps.

I am a matematician teacher in Brazil and I have a alcohol car with 
13 years  of use and until now the motor is like a new one. And at 
this days after a hole in the cooler in a trip of 8.000 km I have 
some troubles of high temperatures. So I had to open the motor. 
But what a surprise. Completly clean motor. Well I thing that I will 
use this motor another 13  years.

Alcohol works fine in a wankel. Some of the carbon in a wankel is due to the burned
old needed to lube the apex seals. 2 cycle oil mixed with the gas solves
this problem.
