PURPOSE: An evaporation gas test apparatus is provided to shorten the test time and reduce costs by allowing for a simultaneous analysis of the evaporation gas generated from all components and specific components of the fuel system. CONSTITUTION: An evaporation gas test apparatus comprises a large housing(21a) having a main closed chamber; a pressure control multi-bag(22a), a mixing fan(24a), a cold/hot coil(25a) and a sensor(31a) arranged in the main closed chamber of the large housing; a small housing(21b) having one or more small closed chambers; a pressure control multi-bag(22b), a mixing fan(24b), a cold/hot coil(25b) and a sensor(31b) arranged in the small closed chamber of the small housing; an air meter(23) arranged in the outside of the large housing and the small housing; a temperature control unit(26) for controlling the temperatures of the main closed chamber and the small closed chamber by circulating cold or hot air through the cold/hot coils; a concentration analysis system(27) for collecting air from the main and small closed chambers and analyzing the concentration of the evaporation gas; a gas stand(28) for storing the standard gas of the concentration analysis system and air and gas required for the operation of the concentration analysis system; a gas manager(29) for distributing the standard gas and air and gas stored in the gas stand; and a fuzzy fan(30) for discharging the evaporation gas from the main and small closed chambers after and prior to the test.
