With a single-cylinder engine, the emission characteristics of two types of hydrogen-rich fuels were evaluated. The first fuel contained various proportions of hydrogen and gasoline. Hydrogen enrichment does not appear to be a sufficient means of reducing HC emission. The second types of hydrogen-rich fuel was a simulated product of an on-vehicle hydrogen generator that reforms gasoline into a gaseous mixture of CO, H2, CH4, and various diluents. Fueling a single-cylinder engine totally on this mixture at an equivalence ratio = 0.55 resulted in NOX and HC emission levels well below those obtainable with gasoline. CO emission was slightly higher than values characteristic of lean operation with gasoline. /GMRL/
