The measured engine fuel flow rate is 0.4g/s, airflow rate is 5.6 g/s and exhaust gas composition (measured dry) is CO2 =13.0% , CO = 2.8% with O2 essentially zero. Unburned hydrocarbon emissions can be neglected. Compare the equivalence ratio calculated from the fuel and airflow with the equivalence ratio calculated from the exhaust gas composition. The fuel is Gasoline with an H/C ratio of 1.87. Assume an H2 concentration equal to one third the CO concentration.
