Research ArticleOpen accessEvery word in the titleAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,299 accessesView PDFCite
