Hydrogen burn rate is modulated to match fossil fuel burn rate
Unmodulated hydrogen has a burn rate of 325-265 cm/sec versus 45-35 cm/sec for hydrocarbon/fossil fuels; the system modulates hydrogen density with non-combustible gases so the modulated burn rate is adjusted downward to 43-37 cm/sec, matching fossil fuel combustion characteristics across engine speeds.
