Abstract:
1. An aging device of a catalytic converter of a vehicle, comprising: an engine for bench testing; a first valve through which an oil additive or an engine oil mixture is injected into the engine, the first valve disposed in an intake line through which intake air flows; a pump that pressurizes and transmits the oil additive or the engine oil mixture from a storage tank to the first valve; a catalytic converter that is disposed in an exhaust pipe through which exhaust gas that is combusted in the engine is exhausted out of the engine; a second valve through which atmospheric air is introduced so as to produce a secondary combustion of unburned exhaust gas, the second valve disposed in the exhaust pipe upstream of the catalytic converter; and a control apparatus that operates thermal and contamination aging of the catalytic converter in a bench test state of the engine under conditions that simulates the operational state of a vehicle.
