Hydrogen combustion in ICE's presents an opportunity to generate an infrastructure for a hydrogen economy. To this end, hydrogen assisted combustion research of spark ignition fuels is a current area of attention. Studies were conducted for natural gas and hydrogen assisted natural gas combustion in a 0.5L single-cylinder Ricardo Hydra single-cylinder research engine to attain 2 Bar BMEP at 2000 RPM under stoichiometric conditions. Throttle position was adjusted to produce increasingly lean air-fuel mixtures for each fuel. Resulting data suggest that the overall burn rate of hydrogen enriched natural gas mixtures is not increased compared to natural gas alone.
