Exhaust gas analysis system, recording medium recorded with program for exhaust gas analysis system, and exhaust gas analyzing method

An exhaust gas analyzing method using an exhaust gas analysis system comprising an exhaust gas circulation line through which exhaust gas flows, an exhaust gas collection line configured to collect the exhaust gas from the exhaust gas circulation line and introduce the collected exhaust gas into an exhaust gas analysis device, a continuous analysis line configured to, separately from the exhaust gas collection line, collect the exhaust gas from the exhaust gas circulation line for continuous analysis, a continuous analyzer provided in the continuous analysis line and configured to measure concentration of a predetermined component contained in the exhaust gas, and an information processing unit, the exhaust gas analyzing method comprising:

• by the information processing unit,
• acquiring concentration measured by the continuous analyzer during a predetermined period at a time of the collection into the exhaust gas analysis device,
• calculating an exhaust gas related value using the acquired concentration, wherein the exhaust gas related value is an average concentration of the predetermined component during the predetermined period, an integrated value of the predetermined component having flowed into the continuous analyzer during the predetermined period, or a fuel consumption during the predetermined period, and
• determining whether a measurement result of the exhaust gas introduced into the exhaust gas analysis device falls within a preset range by comparing the exhaust gas related value to a reference value.
