摘要： The present invention is applied to an internal combustion engine comprising a first supercharger (61), a second supercharger (62), a first control valve (66) for controlling a supply of an exhaust gas to the first supercharger, and a second control valve (64) for controlling a supply of an air to the first supercharger, and provides to an apparatus for determining an abnormality of a control valve which can determine abnormality of the first control valve and the second control valve. The apparatus for determining an abnormality of a control valve determines abnormality of a control valve when a supercharging pressure is smaller than a predetermined referential supercharging pressure by a predetermined value or more. The apparatus for determining an abnormality of a control valve determines that the first control valve is abnormal and the second control valve is normal if a pressure of an air at a downstream side of a compressor of the first supercharger is larger than a pressure of an air at an upstream side of the compressor by a predetermined value or more. In the meantime, the apparatus for determining an abnormality of a control valve determines that either one of the first control valve and the second control valve is abnormal if the pressure of the air at a downstream side of the compressor of the first supercharger is not larger than the pressure of the air at an upstream side of the compressor by a predetermined value or more.

摘要： An exhaust system (38) for use with an engine (10) is disclosed. The exhaust system may have a first treatment device (42) situated to receive a flow of exhaust and convert a first constituent of the exhaust to a second constituent, and a second treatment device (44) located downstream of the first treatment device to reduce the first and second constituents. The exhaust system may also have a sensor (54) configured to generate a signal indicative of one of a temperature and an oxygen concentration of the exhaust, and a controller in communication with the sensor. The controller may be configured to vary the other of the temperature and the oxygen concentration based on the signal such that a desired amount of the first constituent is converted to the second constituent by the first treatment device prior to reduction by the second treatment device.
