AFR-vs.-Power chart

[Craighell]

Does anyone know of a place where I can get a copy of the relative power change when one varies the Air fuel ratio (say from 10:1 through 15:1)?

I realize peak power occurs at different AFR in different engines, but I assume some one like Charles Fayette Taylor or the like has done some base line tests and out lined them in text.

If anyone knows of a site with the details, I would greatly appreciate it.

Thanks,
Craig

Try this link

http://naca.larc.nasa.gov

It is the site of the National Advisory Committee for Aeronautics, which later became NASA. It has a lot of research papers on piston engine efficiency.
