Question about iso-efficiency lines

Hello everyone,
I have a question regarding iso efficiency lines which is confusing me a lot.
Please tell me if this is the wrong forum for this question.

Consider the following graph
hxxp://en.wikipedia.org/wiki/File:Brake_specific_fuel_consumption.svg
Please replace hxxp.
I assumed there would be only 1 bmep at each speed of the engine.
How would one achieve the lowest bsfc? How would one operate with the lowest bsfc and also at a particular bmep?

Thanks.
