PROBLEM TO BE SOLVED: To improve measurement accuracy of an air-fuel ratio, a concentration of each component included in exhaust gas, a fuel consumption determined therefrom or the like by taking the H2O amount omitted by condensation or the like into consideration. ! SOLUTION: The omitted H2O amount which is an amount of H2O omitted by condensation or the like until reaching a measurement point of an air-fuel ratio sensor 3 is calculated based on a saturated steam concentration at an exhaust gas temperature obtained from a temperature sensor 6 and on a temporary H2O concentration obtained from a measured air-fuel ratio. !
