BSFC = Fuel to HP (efficiency, like i stated)
BMEP = Displacement to Work output (independent of fuel input..i.e. cannot gauge effieciency)
When efficiency was mentioned, i said BSFC should be used. Am i wrong?
When comparing and engines power output capability per displacement you should use BMEP.(i.e. great for comparing engines...)
