An alcogas mixture made up of 85 % gasoline (octane no. = 95) and 15 % ethanol is used as fuel for an engine in the presence of 17.05 m3 air/kg alcogas supplied essentially dry at 30 oC and 740 mm Hg. 80 % of the C burns to CO2, the rest to CO. Molal ratio of H2 to CO is 1:2. Calculate: a) Orsat analysis of the exhaust gas b) % excess air %composition CO in the Orsat analysis: %composition CO2 in the Orsat analysis: % excess air:
