摘要：An exhaust gas purifying apparatus for an internal combustion engine isprovided for switching a switching valve at an optimal timing in accordance with an actual

activated state of a catalyzer to achieve an optimal exhaust gas characteristic. Theexhaust gas purifying apparatus comprises a catalyzer disposed in an exhaust system ofthe internal combustion engine, an adsorbent filled in a second passage circumventing afirst passage in the exhaust system for adsorbing hydrocarbons within exhaust gases, aswitching valve operable to switch between an open position for opening the firstpassage and a close position for closing the first passage, an ECU for detecting atemperature state of the exhaust system upon start of the internal combustion engine,and calculating the calory of exhaust gases discharged after the start of the internalcombustion engine, and a switching valve driver for driving the switching valve to theclose position upon start of the internal combustion engine, and driving the switchingvalve to the open position in accordance with the detected start-time temperature stateof the exhaust system, and the calculated post-start exhaust gas calory.
