<p>An exhaust emission control device of internal combustion engine having a simple exhaust emission treatment device structure and capable of efficiently purifying HC within the adsborbing capability of HC adsorbent and a control device for car capable of preventing a drivability from being impaired largely, wherein the adsorbent comprises an adsborbing zone adsorbing unburned hydrocarbon and a desorbing zone allowing the unburned hydrocarbon adsorbed to be desorbed, detects whether a catalyst is in the activated state or not and, when the catalyst is not in the activated state, the output or torque of an engine is regulated so that the temperature of the adsorbent can be maintained in the adsorbing zone until the catalyst reaches the activated state so as to achieve the activated state, whereby, because the adsorbent and exhaust gas treating catalyst is provided in an exhaust gas flow path of the engine, the unburned hydrocarbon contained in the exhaust gas can be adsorbed temporarily to the adsorbent.</p> |
