Good evening, I'm Brazilian, engineering student.
For some time I've been tracking your site.
I performed some presentations in my engineering course on wankel engines, used his posts as references.

I am enthusiastic about this engine, I would like to obtain more information about the compression rate, thermal efficiency, consumption, among others.
In my city/State, there is no vehicle that has this engine. At least, that I'm aware of.

You have, can you tell me some references on where to find this information?

Thanks for the posts, by sharing knowledge.

The Mazda RX8 engine compression ratio is 10:1

The best BSFC we have seen so far is .47. Only slightly higher
than most air cooled aircraft piston engines at .45.

If you have access to google in  Brazil  you can google Mazda RX8
and BSFC.


Brake specific fuel consumption (BSFC) is a measure of the fuel efficiency <http://en.wikipedia.org/wiki/Fuel_efficiency> of any prime mover that burns fuel and produces rotational, or shaft, power. It is typically used for comparing the efficiency of internal combustion engines <http://en.wikipedia.org/wiki/Internal_combustion_engines> with a shaft output.

It is the rate of fuel <http://en.wikipedia.org/wiki/Fuel> consumption divided by the power <http://en.wikipedia.org/wiki/Power_%28physics%29> produced. It may also be thought of as power-specific <http://en.wiktionary.org/wiki/Specific> fuel consumption, for this reason. BSFC allows the fuel efficiency of different engines to be directly compared.


2.5 million Mazda Wankel engines have been sold world wide since 1970.
