摘要： A particulate matter (PM) detection sensor is placed in an exhaust gas pipe of a diesel engine. The PM sensor element has a detection part composed of a pair of detection electrodes and a heater part. The detection electrodes and the heater part are stacked in the PM sensor element. A control circuit instructs a heater power supply to supply electric power to the heater part when the diesel engine is started to operate. The heater part heats the detection part at a predetermined temperature T1 within a range of 600° C. to 900° C. for a predetermined period S1 of time, for example, 650° C. for 20 seconds, in order to burn and completely eliminate particulate matter accumulated in the detection part. This control process avoids incorrect detection of the PM detection sensor. After this process, the control circuit executes usual control of the PM detection sensor.

摘要： In a PM detection sensor S having a PM sensor element 1 installed in an exhaust-gas pipe of an engine E/G, PM detection electrodes are placed in detection spaces in slits, respectively, formed in an insulation substrate. In the insulation substrate, one slit is embedded between an electric field generating electrode and a common electric field generating electrode. The other slit is embedded between an electric field generating electrode and the common electric field generating electrode. The same magnitude of an electric field is generated between the detection spaces when electric power is supplied to the electric field generating electrodes. An average value of sensor outputs transferred from the PM detection electrode is used as a sensor output of the PM sensor element.

摘要： A gas sensor control device is disclosed as including a sensor cell having a negative terminal, to which a current-voltage converter is connected, and a differential amplifier is connected to the current-voltage converter to provide a current measured result applied to a microcomputer. The current-voltage converter has an opposite-to-sensor terminal to which another differential amplifier is connected. A sensor-side terminal of the current-voltage converter and another differential amplifier is electrically connected to each other via an electric pathway having a sensor-current flow disabling pathway in which a switch circuit is provided. Closing the switch circuit allows a potential difference between both terminals of the current-voltage converter is zeroed. With the switch circuit closed, the microcomputer calculates an element current correcting value, while detecting an electromotive force of the sensor cell based on which a failure is determined.
