摘要： An exhaust gas control apparatus for an internal combustion engine, which has a three-way catalyst (21) and a NOX storage-reduction catalyst (22), also includes rich controlling means for performing control to make an air-fuel ratio of exhaust gas rich to reduce NOX stored in the NOX storage-reduction catalyst (22), and controlling means for performing control to ensure that a NOX purifying component is present in the NOX storage-reduction catalyst when reducing the NOX.

摘要： An internal combustion engine control apparatus controls an internal combustion engine including: an exhaust passage (4) comprised of branch portions (5L, 5R) provided for the left and right banks (2L, 2R) and a common portion (6) in which an exhaust gas purification device (7) is provided; and a fuel supply system (10) that supplies fuel to the respective engine cylinders (3). In the internal combustion engine, in order to recover the exhaust gas purification device (7), a bank control is executed in which the air-fuel ratio of the cylinders (3) of the left bank (2L) is made rich while the air-fuel ratio of the cylinders (3) of the right bank (2R) is made lean. The internal combustion engine is capable of running on alcohol-containing fuel and has an alcohol concentration sensor (13). The amount of unburned fuel to be supplied to the exhaust gas purification device (7) during the bank control is adjusted based on the alcohol concentration in fuel.

摘要： An upstream catalyst (28U) and a downstream catalyst (28D) are arranged in series and are housed in a common casing (25) disposed in an engine exhaust passage. The upstream catalyst (28U) consists of a NOx storage -reduction catalyst that adsorbs NOx contained in incoming exhaust gas when the air-fuel ratio of the incoming exhaust gas is lean, and releases and reduces the adsorbed NOx when the air-fuel ratio of the incoming exhaust gas becomes rich, and the downstream catalyst consists of a three-way catalyst. The upstream catalyst has a higher oxidizing capability than the downstream catalyst, and the downstream catalyst has a higher reducing capability than the upstream catalyst. The upstream catalyst has a multi-layer structure including an upper layer and a lower layer, and is prepared such that the upper layer has a higher oxidizing capability than the lower layer, and the lower layer has a higher reducing capability than the upper layer.
