PARTICULATE MATTER DETECTING SENSOR AND PARTICULATE MATTER DETECTING APPARATUS |
摘要 |
A particulate matter detecting apparatus that measures an amount of particulate matter in a gas by applying a predetermined voltage between a pair of first electrodes of a sensor element portion includes a detecting portion that detects whether more particulate matter than a reference amount has accumulated on the first electrodes, a temperature controlling portion that controls a temperature of the sensor element portion to become equal to or higher than a reference temperature when it is detected that more particulate matter than the reference amount has accumulated, and a voltage controlling portion that applies a reference voltage between the first electrodes and a second electrode arranged such that a solid electrolyte is sandwiched between the second electrode and the first electrodes, when it is detected that more particulate matter than the reference amount has accumulated. |
