Abstract
An exhaust gas measuring apparatus includes an atmosphere introducing unit, an air purifier, a diluting unit, selecting means, a sampling unit, and measuring means. The atmosphere introducing unit takes in air in the atmosphere as diluting air. The air purifier takes in and purifies air in the atmosphere, thereby generating diluting air. The diluting unit dilutes a portion of exhaust gases of an engine with the diluting air. The selecting means causes either one of the atmosphere introducing unit and the air purifier to communicate with the diluting unit. The sampling unit collects diluted exhaust gases. The measuring means obtains the emission amount of collected exhaust gases.
