The production of hydrogen and syngas from natural gas using a homogeneous charge
compression ignition reforming engine is investigated numerically. The simulation tool
used was CHEMKIN 3.7, using the GRI-3 natural gas combustion mechanism. This simulation
was conducted on the changes in hydrogen and syngas concentration according to
the variations of equivalence ratio, intake temperature, oxygen enrichment, engine speed,
initial pressure, and fuel additives with partial oxidation combustion. The simulation results
