An ultimate analysis of gasoline sample gave carbon 85%, hydrogen 15%. Calculate the ratio of air to gasoline consumption by weight if the volumetric analysis of the dry exhaust gas is CO2 = 11.5%; CO = 1.2%; O2 = 0.9%; and N2 = 86%. Also, determine the % of excess air required for complete combustion.
