    摘要： An adsorbent diagnostic apparatus for an emission control apparatus is able to precisely determine whether an adsorbent for adsorbing unburned gas components has a fault or a deterioration. The diagnostic apparatus has an air-fuel ratio detector that is provided in a portion of the exhaust passage downstream of the adsorbent, and a controller that controls the amount of the previously adsorbed unburned gas component released from the adsorbent to the air-fuel ratio detector. Tic controller determines whether the adsorbent has a fault or a deterioration, based on a detection value of the air-fuel ratio detected by the air-fuel ratio detector, when the amount of the unburned gas component released from the adsorbent remains stable.

    摘要： A hydrocarbon adsorption apparatus is provided in an exhaust passage of an internal combustion engine. The hydrocarbon adsorption apparatus is equipped with a main passage, a switching valve for opening and closing the main passage, and a bypass passage for bypassing the main passage. The switching valve is coupled to a diaphragm of a diaphragm mechanism. A variable chamber in the diaphragm mechanism is connected to an intake manifold through a negative pressure feed line and a vacuum switching valve. When the vacuum switching valve is turned on, a negative pressure is supplied to the variable pressure chamber so that the diaphragm is deflected. In response to the deflection of the diaphragm, the switching valve is closed. The state of the switching valve is judged based on a tendency of changes in pressure of the negative pressure feed line when the vacuum switching valve is turned on.
