Abstract

An exhaust monitoring apparatus (100) sets a transport delay time (TL) spanning from when air passes through a portion of an intake passage (19) where an air flow meter (20) is provided to when exhaust gas derived from the air that has passed through the air flow meter (20) reaches a nitrogen oxide sensor (17). The exhaust monitoring apparatus (100) estimates an emission amount of nitrogen oxides based on an output value of the nitrogen oxide sensor (17) and an output value of the air flow meter (20) that was output earlier than a point in time at which the nitrogen oxide sensor (17) output the output value by the transport delay time (TL).
