EGT versus equivalence ratio, methane fuel

[ivymike]

Hey, does anyone have a link or reference for a plot of exhaust gas temperature versus equivalence ratio, lambda, or AFR for a (any) natural gas fueled engine? Just need something that I can use to show a generic relationship for discussion purposes.

it'll depend heavily on ignition timing, valve/port timing and the distance the EGT is from the port/valve.
