Thanks mark, I know that the Euro spec W123 was a higher compression engine, I wonder if compression would have an effect on the "demand" for combustable air mixture.


On the topic of fluid design: How does one go about calculating the demand for combustable air? I am thinking that it is a function of displacment and RPM. for example f(x)= 2500x*6*rpm

And then there would be the issue of mixture, I would assume that the ideal mixture is stated somewhere on the web. I will post more when I find some info.

That was easy see : http://en.wikipedia.org/wiki/Lean_burn
