In-vehicle exhaust gas analysis system, in-vehicle exhaust gas analysis system inspection system, and in-vehicle exhaust gas analysis system inspection method

摘要

PROBLEM TO BE SOLVED: To simplify an inspection of a vehicle-boarded type emission gas analysis system, and to inspect an entire system combining a flowmeter and emission gas analysis meter.SOLUTION: A vehicle-boarded type emission gas analysis system 10, which has a flowmeter 2 measuring a flow rate of emission gas and an emission gas analysis meter 3 analyzing density of a measurement object component to be contained in the gas, comprises: a standard gas supply mechanism 5 that supplies standard gas including a prescribed component to the flowmeter 2 and the emission gas analysis meter 3; an insection mass calculation unit 63 that calculates inspection mass of the prescribed component, using the flow rate obtained by the flowmeter 2, and the density of the prescribed component obtained by the emission gas analysis meter 3; a supply mass acquisition unit 64 that acquires supply mass of the prescribed component supplied to the flowmeter 2 and the emission gas analysis meter 3 from the standard gas supply mechanism 5; and a mass comparison unit 65 that compares the inspection mass calculated by the mass calculation unit 63 with the supply mass acquired by the supply mass acquisition unit 64.SELECTED DRAWING: Figure 2
