摘要： PROBLEM TO BE SOLVED: To provide an ammonia gas detector constituted so that the detection output of an impedance change type detection element with respect to the ammonia gas component in a gas to be detected is set after the adhesion component of a responsive membrane is removed by the heating of the detection element and the detection output of the detection element is corrected on the basis of the set output to precisely detect the ammonia gas component, and an ammonia gas detecting method.
SOLUTION: The impedance change type detection element 70 responds to the ammonia gas component contained in an exhaust gas on the downstream side of a selective reducing catalyst 14 and utilizes the hopping conduction of a proton to detect the ammonia gas component to generate output voltage. A microcomputer sets the output voltage from the detection element 70 as zero point voltage after the heat treatment of the detection element 70 and subsequently calculates the change rate to zero point voltage to correct the output voltage from the detection element 70.

摘要： PROBLEM TO BE SOLVED: To improve the sealability between an outer jacket and a protective outer jacket by suppressing the deformation of a separator in a gas sensor. SOLUTION: The gas sensor 1 is provided with the separator 16 which protects the connection between a lead frame 25 connected to the electrode section 11b of a detecting element 11 and lead wires 18, and prevents the infiltration of water, oil, etc., into the sensor 1 from the space between the outer jacket 13 and the protective outer jacket 14 by means of a rubber packing 15 provided around the separator 16. The deformation of the separator 16 can be prevented by providing a metallic protective cover 24 between the separator 16 and packing 15. Consequently, the sealability between the jackets 13 and 14 is improved, because spaces do not occur between the jackets 13 and 14 and the packing 15 due to the deformation of the separator 16.

摘要： PROBLEM TO BE SOLVED: To provide a soot detecting apparatus which is meant to minimize the variation in a discharge voltage produced at a pair of electrodes of a discharge sensor for improving the detection accuracy of soot.
SOLUTION: When a high-voltage generator circuit 500 generates a high voltage at each conduction of a transistor 420, based on individual pulse signals from a pulse signal generation circuit 410; while a relay 620 of a switching circuit 600 is driven by a drive circuit 610, the high voltage is applied to the discharge sensor 200 with closing both relay switches 622, 623 accompanying the drive of the relay 620. As a result, the deposits of a center electrode 232 are cleaned by the discharging of the discharge sensor 200. After that, when the relay 620 stops, the high voltage from the high-voltage generator circuit 500 is applied to the discharge sensor 200, with both relay switches 624, 625 being closed accompanying the stoppage of the relay 620. Accordingly, a first soot concentration signal is detected, based on the discharge voltage produced in the discharge sensor 620.
