Failure detection device for exhaust purification filter |
| abstract |
A fault detection device for an exhaust purification filter that can detect a fault with high accuracy while using an electrostatic dust collection type particulate matter sensor. A failure detection device for a DPF according to the present invention performs a sampling process (S3) in which PM is attached to a sensor electrode part by applying a predetermined voltage to the sensor electrode part, and then the static of the sensor electrode part is detected. A measurement process (S4) for measuring the capacitance change amount ΔC is executed. Further, an operation state parameter (revolution speed N, fuel injection amount W) indicating the operation state of the engine during the sampling process is recorded, and this operation state parameter (revolution speed N, fuel injection amount W) is recorded. And failure of the DPF is detected based on the measured capacitance change amount ΔC. [Selection] Figure 3 |
