IN-VEHICLE EXHAUST GAS ANALYSIS SYSTEM, INSPECTION SYSTEM FOR IN-VEHICLE EXHAUST GAS ANALYSIS SYSTEM, INSPECTION METHOD FOR IN-VEHICLE EXHAUST GAS ANALYSIS SYSTEM, AND INSPECTION PROGRAM

In order to simplify an inspection of an in-vehicle exhaust gas analysis system as well as to inspect the entirety of the system combining a flowmeter and exhaust gas analyzer, an in-vehicle exhaust gas analysis system 10, which is provided with a flowmeter 2 to measure a flow rate of exhaust gas, and an exhaust gas analyzer 3 to analyze a concentration of a measurement target component contained in the exhaust gas, includes a standard gas supply mechanism 5 to supply a standard gas containing a predetermined component to the flowmeter 2 and the exhaust gas analyzer 3. The system 10 is configured to include a detected mass calculation section 63 to calculate a detected mass of a predetermined component by using a flow rate obtained by the flowmeter 2 and a concentration of the predetermined component obtained by the exhaust gas analyzer 3; a supply mass acquisition section 64 to acquire a supply mass of the predetermined component supplied from the standard gas supply mechanism 5 to the flowmeter 2 and the exhaust gas analyzer 3; and a mass comparison section 65 to compare a detected mass calculated by the mass calculation section 63 and a supply mass acquired by the supply mass acquisition section 64.
