摘要： An exhaust gas purifying system includes: a NOx trapping agent (2) which adsorbs nitrogen oxide when an excess air ratio of exhaust gas is more than 1, and releases nitrogen oxide when the excess air ratio is 1 or less; a NOx purifying catalyst (13) which reduces nitrogen oxide to nitrogen; and an oxygen concentration controller which controls oxygen concentration in the exhaust gas. When the excess air ratio of the exhaust gas is more than 1, nitrogen oxide is adsorbed to the NOx trapping agent (2). When the excess air ratio of the exhaust gas is 1 or less, the oxygen concentration controller controls the oxygen concentration of the exhaust gas at an inlet of the NOx purifying catalyst between 0.8 and 1.5% by volume, so that the NOx purifying catalyst reduces nitrogen oxide released from the NOx trapping agent.

摘要： In an internal combustion engine, a hydrocarbon feed valve (15), NOx storage catalyst (13), particulate filter (14), and electric resistance type sensor (29) are arranged in an engine exhaust passage in this order from an upstream side. The electric resistance type sensor (29) generates an output value corresponding to the amounts of deposition of particulate matter and hydrocarbons which are contained in the exhaust gas and deposited at the sensor part thereof. From the change of the output value of the electric resistance type sensor (29), it is judged if the hydrocarbons have slipped through the NOx storage catalyst (13) and if the particulate matter has slipped through the particulate filter (14).

摘要： The invention relates to a method to determine the HC-conversion efficiency of a catalyst, which is situated in the exhaust gas flow path of an internal combustion engine and which is configured to convert hydrocarbons, by means of an oxygen-sensitive sensor that is installed downstream from the catalyst in the exhaust gas flow path and that exhibits a cross sensitivity to hydrocarbons. The method comprises: detecting a first signal of the downstream sensor in a first situation in which a first HC fraction is present in the exhaust gas upstream from the catalyst; detecting a second signal of the downstream sensor in a second situation in which a second HC fraction that is higher than the first HC fraction is present in the exhaust gas upstream from the catalyst; and determining the HC-conversion efficiency of the catalyst as a function of the first and second signals of the downstream sensor.

摘要： An exhaust gas purification system uses an NOx purification apparatus for reducing the amount of precious metal used and exhibits an NOx purification performance at a low temperature and/or in an oxidizing atmosphere, and provides NOx purification performance even by an exhaust gas composition including HC and NOx at the time of a non-steady operation. An exhaust gas purification system using an NOx purification apparatus with an NOx purification catalyst in an exhaust gas passage has a carrier for nanoparticles including gold atoms and nickel atoms in close proximity and an apparatus for predicting the amount of exhaust of NOx. When it is predicted that NOx will be exhausted, carbon monoxide is increased in the exhaust gas fed to the NOx purification catalyst, and, when it is predicted that NOx will not be exhausted, exhaust gas exhausted from an engine is purified without injection of excess fuel.

摘要： In an internal combustion engine, an NOx selective reduction catalyst (15) is arranged in the engine exhaust passage, and the amount of deposition of the HC deposited at the NOx selective reduction catalyst (15) is estimated. When the estimated HC deposition amount exceeds a predetermined allowable deposition amount, the NOx selective reduction catalyst (15) is raised in temperature to make the deposited HC desorb from the NOx selective reduction catalyst (15), and thereby the NOx selective reduction catalyst (15) from HC poisoning is restored.
