This paper compared the effects of hydrogen and hydrogen–oxygen blends (hydroxygen) additions on the performance of a … engine equipped with a hydrogen and oxygen injection system. A hybrid electronic control unit was applied to adjust the … hydrogen and hydroxygen volume fractions in the intake increasing from 0% to about 3% and keep the hydrogen-to-oxygen mole …

fuel amount, total flow rate and O/C ratio were evaluated. The production rates of both hydrogen and carbon monoxide were …
