摘要： PROBLEM TO BE SOLVED: To enable the failure determination of a particulate filter without measuring the precise amount of accumulation of the PM of the particulate filter.SOLUTION: This failure detecting device 1 includes particulate sensors 41 and 42 on the upstream side and downstream side of a particulate filter (DPF 30). Both the sensors can specify the amount of particulates passing themselves. The output ratio (PM discharge ratio) of both the particulate sensors 41 and 42 is computed, and when focucing attention on fluctuation of this ratio, it is found that the failed particulate filter indicates a change in which the PM discharge ratio has the minimum value after the PM discharge ratio has once dropped, and rises again, and the failure of the particulate filter is determined based on this.

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.

摘要： PROBLEM TO BE SOLVED: To reversibly and continuously measure a concentration of catalyst poison gas such as CO, without requiring a restoration means such as a heater, and to measure the concentration of catalyst poison gas without being affected by a concentration of H 2 O. SOLUTION: An electric circuit 15 for a gas sensor has an alternating current source 19 for impressing an alternating current between both electrodes 3, 5, an A.C voltmeter 21 for measuring an alternating current voltage (alternating current active voltage V) between the both electrodes 3, 5, and an A.C ampere meter 23 for measuring a current (alternating active current I) between the both electrodes 3, 5. The alternating current is impressed between the both electrodes 3, 5 to find an impedance based on the alternating current active voltage V and the alternating active current I generated therein. The concentration of catalyst poison gas is found based on the impedance, using a map indicating a relation between the impedance and the concentration of catalyst poison gas, because the impedance corresponds to the concentration of catalyst poison gas.
