摘要： PROBLEM TO BE SOLVED: To correctly judge an abnormal state in which correct operation is not possible due to operation failure even in a period when an engine operates in a steady state for a long time. SOLUTION: An electric instruction (is) for monitoring abnormality is output for an EPC valve and, as a result, a detection value S of a sensor obtained when the electric instruction (is) for abnormality monitoring is output for the EPC valve is compared with the electric instruction (is) for monitoring abnormality. In the case in which a level of the detection value S of the sensor is appropriate for a level of a signal of the electric instruction (is) for abnormality monitoring, it is judged that a hydraulic servo valve operates normally. The detection value S of the sensor obtained when the electric instruction (is) for abnormality monitoring is output for the EPC valve is compared with the electric instruction (is) for abnormality monitoring and the level of the detection value S of the sensor is inappropriate for the level of the signal of the electric instruction (is) for abnormality monitoring, it is judged that the hydraulic servo valve operates abnormally.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device of an internal combustion engine capable of increasing the functions of an exhaust emission post- treatment device by uniformizing the flow of exhaust emission into the exhaust emission post-treatment device. SOLUTION: A straightening device 50 comprising a projected part 32 and a communication opening 51 for the projected part are provided at the inlet side of the exhaust emission post-treatment device 10 comprising a carrier having a DPF and catalyst carried thereon. The open area of the communication opening 51 at the base end side of the projected part 32 is increased more so that the exhaust gas flowing from the base end side to the tip side can easily flow into an inlet chamber 23 at the base end side. Accordingly, by the relation of the flowing direction of the exhaust gas in the projected part 32 with the opening area of the communication opening 51, a flow distribution at a time point when the exhaust gas flows from the communication opening 51 into the inlet chamber 23 is optimized, and a flow distribution when the exhaust gas flows into the exhaust emission post-treatment device 10 is uniformized.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device of an internal combustion engine capable of minimizing the amount of consumption of a reducer and improving the purification efficiency of NOx.
SOLUTION: The exhaust emission control device 1 comprises a reducer injection nozzle 72 disposed in an exhaust port 31 and a reducer feed controller 80 controlling an electromagnetic valve 74 so as to inject the reducer into the exhaust port 31 while an exhaust valve for each cylinder 11 is closed. By controlling the injection timing of the reducer by a reducer feed controller 80 while the exhaust valve is closed, the reducer can be retained in the exhaust gas for a specified time. Accordingly, hydrocarbon which is allowed to react easily with the catalyst in an NOx reduction catalyst device 71 is allowed to always come into contact with the NOx reduction catalyst device 71. Thus, the purification efficiency of NOx is improved, and also the use amount of the reducer is minimized.

摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine equipped with an intake air bypass-controlling device capable of preventing a compressor from approaching a surging region and obtaining a good torque. SOLUTION: An outlet passage of the compressor 21 and an inlet passage of an exhaust turbine 22 of an exhaust-turbo supercharger 20 are communicated through a bypass duct 23, and the bypass duct 23 is provided with a bypass valve 24. When the operation status of the diesel engine 1 is in a low speed/high load region, a valve controller 30 controls the bypass valve 24 for adjusting the bypass duct 23 to the opening direction. As a part of inlet air flows into an exhaust duct 4, the exhaust turbine 22 rotates faster and an intake air volume increases, which makes the output of the diesel engine 1 increase. The increase of the intake air volume prevents the compressor 21 from approaching the surging region. COPYRIGHT: (C)2005,JPO&NCIPI
