    Abstract: Exhaust gas is caused to flow through a bypass passage during an adsorption mode. At this time, an adsorbing member adsorbs harmful components, e.g. HC, of the exhaust gas. Also, exhaust gas is caused to flow through the bypass passage to thermally desorb the harmful component held at the adsorbing member during a desorption mode. A quantity of heat given from exhaust gas to the adsorbing member during the desorption mode is calculated based on an operation state of an engine. It is determined that the desorption of the harmful components has been finished when the quantity of heat given to the adsorbing member reaches a total quantity of heat required for totally desorbing the harmful components adsorbed by the adsorbing member.

    Abstract: An exhaust gas purifying apparatus with a failure diagnosis function is provided. A failure diagnosis device determines that the apparats is failed when the temperature rising speed of an adsorbing device is equal to a set value or less during a gas adsorption process and if the temperature rising speed is equal to an upper limit or more or to a lower limit or less during a gas desorption process. Further, a failure diagnosis device similarly monitors the flow passing through the adsorbing device. A failure diagnosis device determines that the apparatus is failed if the concentration of discharge gas is equal to a set value or more in a discharge passage. And further, a failure diagnosis device measures the concentration of discharge gas flowing through a return passage to accumulate the amount of discharge gas in order to determine that the apparatus is failed if the accumulated value is equal to a set value or less. Exhaust gas sensors are installed in the return passage and the upstream side of the adsorbing device, respectively, and the period of time te from the activation of the return passage until the outputs from the exhaust gas sensors match or a correlation coefficient for these outputs is measured to diagnose failures in the apparatus.

    Abstract: Two flow paths separated by a partition wall having a bore formed downstream of a catalyst unit provided in an exhaust pipe of an internal combustion engine. Adsorption means for adsorbing an HC component of an exhaust gas of the internal combustion engine is provided in one of the flow paths. When a temperature of the exhaust gas is above a predetermined level, the exhaust gas flows through the other flow path by means of a change-over valve. Because the bore is provided in the partition wall, the adsorption means is exposed to the exhaust gas and the HC component adsorbed by the adsorption means is easily desorbed because of the high temperature of the exhaust gas. A one-way valve which repeatedly performs an opening/closing operation due to pulsation of the exhaust gas, is provided between recirculation flow pipes. A position of the one-way valve between the recirculation flow pipes is determined so that a phase difference between the exhaust gas pulsation applied to the valve from the upstream side of the catalyst unit and the exhaust gas pulsation applied to the valve from the flow path of the adsorption means, inverts substantially by half-wavelength producing a large differential pressure applied to both the front and rear surfaces across the one-way valve, thereby rapidly recirculating the desorbed HC from the adsorption means to the catalyst unit. When the change-over valve is operated to a position shown by a dotted line to flow the exhaust gas through the adsorption means, the flow-in velocity of the exhaust gas flowing into the adsorption means is made uniform by the rectifying plate, thereby improving HC or the like adsorbing efficiency. When the change-over valve is turned to a position shown by a solid line for opening the exhaust gas flow path, so that the exhaust gas flows through the exhaust gas flow path, the rectifying plate prevents vortices from occurring on the upstream side of the adsorption means to thereby keep the once-adsorbed HC or the like from flowing out toward the exhaust gas pipe.
