Lots of graphs, few references but the graphs don't seem to be just made up.
If this all is true then it seems that small quantities of hydrogen allow for more EGR in a regular engine, making it more economical at light loads - right what we can use.

I don't think the oxygen content in oxyhydrogen would make matters worse; the fact that it compensates for the hydrogen would only make it easier to regulate the gas flow by the oxygen sensor.

Whether that is enough to overcome the cost of making hydrogen - I'd still prefer to distract it separately from the oxygen and only mix them in the intake - that remains to be seen.
It may take 10% of the engine produced power to generate 1% worth of hydrogen. That may be too much.

Bottom line is that even if it does work it still needs reprogramming of the EGR flow ratios.
