ABSTRACT:
An exhaust gas analyzer includes a main flow path and at least one sub-flow path. Exhaust gas from an internal combustion engine is introduced to the main flow path; sub-flow paths are parallel to the main flow path. Plural kinds of analyzers are mounted on the main flow path and sub-flow paths to measure concentration of multiple components in the exhaust gas. Actual measurement values of the concentration for the measured components are obtained. A deviance from a true value generated to an actual measurement value due to a mutual influence of the measured components is corrected based on at least one actual measurement value.
