| Abstract | ||||
| An experimental program to research, develop and demonstrate an axially two staged combustor with premixed gasoline/all and hydrogen/air mixtures is described. Radial and axially profiles for species concentrations and gaseous temperatures are obtained for a wide range air-fuel ratios and degree of charge stratification. Two design parameters were varies namely, the connecting orifice diameter and the burner diameter. Three different orifice diameters are used, those are 20, 25 and 30 mm, and two different burner diameters are used, 5 and 6 mm. The results obtained showed that at higher values of excess air factor in the main chamber, Co does not consumed completely before the exit from the combustor. At higher values of excess air factors in the pre- and pain chambers, the combustion efficiency was ensured within the combustor length. Decreasing the connecting orifice diameter improves the turbulent and decreasing the flame length. A stratified charge combustion has been studies for leaner combustion to improve emissions and fuel economy. The carbon monoxide is decreased while the combustion efficiency is increased with increasing the degree of charge stratification. The same benefits are obtained when increasing the amount of hydrogen fuel in the mixtures. | ||||
