| titleOfInvention | NOx sensor abnormality diagnosis method, NOx sensor abnormality diagnosis system, and internal combustion engine |
| abstract | An NOx sensor abnormality diagnosis method, a NOx sensor abnormality diagnosis system, and an internal combustion engine capable of continuously performing abnormality diagnosis of a NOx sensor by comparing a calculated value of NOx concentration with a detected value of a NOx sensor. I will provide a. A detection value m_air of an intake air amount sensor 31 arranged in an intake passage 12 of an internal combustion engine 10, a detection value Ti of a first temperature sensor 32 arranged in an intake manifold 11a, and a first value arranged in the intake manifold 11a. The detection value Pi of the pressure sensor 33, the detection value Te of the second temperature sensor 34 disposed in the exhaust manifold 11b, the detection value Pe of the second pressure sensor 35 disposed in the exhaust manifold 11b, and the exhaust passage 18 The NOx concentration NOx_cyl is calculated from the detected value λ_egr of the excess air ratio sensor 36, and the calculated NOx concentration NOx_cyl is compared with the detected value NOx_m of the NOx sensor 37, and the NOx sensor 37 disposed in the exhaust passage 18 is compared. Diagnose whether there is an abnormality. [Selection] Figure 1 |
