A bypass passage 18 bypassing a main exhaust passage 12 of the internal combustion engine 10 is provided. A HC/NOx adsorbent 22 having a function of adsorbing HC and NOx is provided in the bypass passage 18. A second underfloor catalyst 30 is provided downstream of the adsorbent 22. A purge passage 26 branching off from the bypass passage 18 while connecting to an intake passage is provided. An exhaust switching valve 20 and a purge control valve 28 are provided as a flow path switching means that is capable of switching a flow target into which the exhaust gas flows between the main exhaust passage 12 and the bypass passage 18. If the purging operations are executed, the intake purging operation is first executed. After that, the intake purging operation is switched to the exhaust purging operation at a timing existing after the purge of NOx is completed and at the time point at which the temperature of the adsorbent becomes stable.

摘要： The present invention relates to an exhaust emission control device having an NOx adsorbent, and makes it possible to judge whether the performance of the NOx adsorbent is degraded temporarily or permanently. The amounts of NOx and water adsorbed by the NOx adsorbent are measured during an actual operation of an internal combustion engine. A reference line indicating the correlation between a preselected water adsorption amount and NOx adsorption amount is then referenced to determine a reference value y0 of the NOx adsorption amount that corresponds to a measured value x1 of the water adsorption amount. Next, a measured value y1 of the NOx adsorption amount is compared against the reference value y0 to output a signal in which the result of the comparison is reflected.

摘要： A converter containing a NOx absorbing and reducing catalyst is disposed in the exhaust passage of an internal combustion engine. The upstream half portion (portion of the inlet side) of the substrate of the NOx absorbing and reducing catalyst in the converter carries the oxygen storage component that absorbs oxygen in the exhaust gas when the air-fuel ratio of the exhaust gas is lean and releases the absorbed oxygen when the air-fuel ratio of the exhaust gas flowing in is rich in addition to carrying the NOx absorbing and reducing catalyst. After NOx is absorbed by the NOx absorbing and reducing catalyst as a result of operating the engine at a lean air-fuel ratio, the engine is operated at a rich air-fuel ratio, so that NOx is released from the NOx absorbing and reducing catalyst and is purified by reduction. Here, oxygen is released from the oxygen storage component carried by the upstream half portion of the substrate and is reacted with the H2 and CO components in the exhaust gas, so that the temperature of the NOx absorbing and reducing catalyst is raised within short periods of time due to the heat of reaction. Therefore, the catalyst exhibits increased activity and the NOx absorbing and reducing catalyst exhibits improved NOx purification capability.

摘要： In an exhaust gas purification device, a three-way catalyst, an NO.sub.x absorbing-reducing catalyst and an NH.sub.3 adsorbing-denitrating catalyst are disposed in an exhaust gas passage of the internal combustion engine. The engine is provided with direct cylinder injection valves which inject fuel directly into the respective cylinders. A control circuit controls the amount of fuel injected from the injection valve so that the air-fuel ratio of the combustion in the cylinders becomes a lean air-fuel ratio during the normal operation of the engine. Therefore, a lean air-fuel ratio exhaust gas is discharged from the cylinders during the normal operation and NO.sub.x, in the exhaust gas is absorbed by the NO.sub.x absorbing-reducing catalyst. When the amount of NO.sub.x absorbed in the NO.sub.x absorbing-reducing catalyst increases to a predetermined level, the control circuit performs an additional fuel injection during the expansion stroke or exhaust stroke of cylinders in order to adjust the air-fuel ratio of the exhaust gas leaving the cylinders to a rich air-fuel ratio. The rich air-fuel ratio exhaust gas leaving the cylinders flows into the three-way catalyst and NO.sub.x in the exhaust gas is converted into NH.sub.3 at the three-way catalyst. When the rich air-fuel ratio exhaust gas flows through the NO.sub.x absorbing-reducing catalyst, NO.sub.x is released from the NO.sub.x absorbing-reducing catalyst and is reduced to N.sub.2 by NH.sub.3 in the exhaust gas.
摘要翻译：在排气净化装置中，在内燃机的废气通道中设置三元催化剂，NOx吸收还原催化剂和NH 3吸附脱硝催化剂。发动机配有直接气缸喷射阀，其将燃料直接喷射到相应的气缸中。控制电路控制从喷射阀喷射的燃料量，使得在发动机的正常运行期间气缸中的燃烧空燃比变为稀空燃比。因此，在正常操作期间，从空气中排出贫空燃比废气，并且排气中的NOx被NOx吸收还原催化剂吸收。当NOx吸收还原催化剂吸收的NOx的量增加到预定水平时，控制电路在气缸的膨胀冲程或排气冲程期间执行额外的燃料喷射，以便调节离开废气的空燃比气缸以较高的空燃比。离开气缸的富空燃比废气流入三元催化剂，废气中的NOx在三元催化剂下转化为NH3。当富空燃比废气流过NOx吸收还原催化剂时，NOx从NOx吸收还原催化剂释放，并通过排气中的NH 3还原为N2。

摘要： In an exhaust gas purification device, a No. 1 cylinder of the engine is operated at a rich air-fuel ratio and other cylinders (No. 2 to No. 4) are operated at a lean air-fuel ratio. The exhaust gases from the No. 1 and No. 2 cylinders are mixed with each other to form a rich air-fuel ratio exhaust gas mixture. Further, since the air-fuel ratio of the No. 2 cylinder is lean, the exhaust gas from the No. 2 cylinder contains a relatively large amount of NO.sub.x. This rich air-fuel ratio exhaust gas mixture which contains a relatively large amount of NO.sub.X is supplied to a three-way catalyst. At the three-way catalyst, part of the NO.sub.X in the exhaust gas mixture is converted to NH.sub.3. The exhaust gas mixture flowing out from the three-way catalyst and the lean exhaust gas from the No. 3 and No. 4 flow into a common exhaust gas passage where they mix with each other to form a lean exhaust gas containing NH.sub.3 from the three-way catalyst and NO.sub.X from the No. 3 and No. 4 cylinders. This lean exhaust gas flows into a denitrating catalyst disposed on the common exhaust gas passage in which NO.sub.X in the exhaust gas is reduced by the NH.sub.3.

摘要： In a remaining fuel amount measuring apparatus for a fuel tank which is suited to the fuel tank designed to suppress generation of fuel vapor, a CPU actuates a piston to supply a prescribed amount of air into a pressure adjusting chamber, thereby increasing the pressure within the pressure adjusting chamber. From the Boyle's law, the increasing rate of air before air supply is inversely proportional to the volume V of the pressure adjusting chamber. Therefore, the CPU, referring to the pressure within the pressure adjusting chamber before and after the air supply, acquires the volume V of the pressure adjusting chamber, and subtracts the volume V of the pressure adjusting chamber from the internal volume of a tank body to acquire the volume of a fuel chamber, i.e. remaining fuel amount.
