An Experimental Study Combustion and Emission Characteristics of HCNG with Dual Spark plug in a Constant Volume Chamber 2011-28-0019

Finding an alternative fuel and solving the environmental pollution are the main targets for the future internal combustion engines. CNG(Compressed Natural Gas) bus is used for a public transportation in Korea because it has low carbon/hydrogen ratio and discharges low pollutant emissions. But CNG fuel has low burning rate. Therefore, in this study, hydrogen is added and DSP(Dual Spark Plugs) are used for making up for the demerits in CNG.HCNG(Hydrogen-CNG) as a fuel is now considered as one of the alternative fuels due to its low pollutant emissions and high burning rate. An experimental study was carried out to obtain the fundamental data about the combustion and emission characteristics of premixed hydrogen and CNG in a CVC(Constant Volume Chamber) with various fraction of Hydrogen-CNG blends using SSP(Single Spark plug) and DSP.
