Effects of reformer gas addition on a spark-ignition engine 2007-24-0015

This paper evaluates the potential of adding simulated reformer gases in a spark-ignition engine to improve the global performances and pollutant emissions. The global composition of the simulated reformer gas is 24% CO -31% H2 - 45% N2 and the quantity of reformer gas added in the engine is varied from 0% to 50%. For all working conditions, the Indicated Mean Effective Pressure is kept constant equal to 3 bars. Intake pressure and ignition timing are adjusted to optimize the coefficient of variation of the Indicated Mean Effective Pressure. Engine performances and pollutants emissions are analysed to point out the best working conditions.
