Thanks for the replies guys.
Well I can see why you went to a more simplfied map with MF2, that matrix is dizzying.
I have studied the graph in the MF2 manual many times. It's easier to read in color ;-) Thank's Richard. Here is what I don't understand: the "injection rate %" description of the Z axis.
A: Is that the percentage of water injected compared to fuel?
B: Or is it the percentage of time that the water injection valve is open, thus the "rate" would depend on the jet size/flow and pressure?
Based on what I have read, 65% of fuel (the peak at 1 Bar boost) as the amount of water injected is very high, and I would have to assume no intercooler in the works. Option B seems the more likely interpretation, but I really don't know.
If it's option 'B', then the amount of water injection is not readily determined from the graphs. Is the water injection rate the maximum 150 ml/min from the standard 0.5 mm jet at 4 bar pressure? Thus we are looking a percentages of this rate?
So Ed, I would like to do just as you say "with jets sized to a % of the injectors' potential".
In either case I don't know what the "% of the injectors" number is-- 15%, 25%, 50%.
If the max water rate is 25% of the max fuel injection rate, and Richard's graph is showing 65% of 25%, that's a 16.5% water to ratio to the fuel. That seems about right.
Let me know the many ways I am confused.
