  • Patent number: 8915119
    Abstract: A detection apparatus includes a particulate matter (PM) detection unit, a temperature detection unit, and a correction unit. The PM detection unit includes an insulator, a pair of electrodes, and a detector. The insulator is disposed in an exhaust path of an internal combustion engine through which an exhaust gas flows. The pair of electrodes are arranged in contact with at least a part of the insulator. The detector detects a PM detection value which is a value correlated to an amount of PM in the exhaust gas. The temperature detection unit detects at least one of an exhaust temperature of the exhaust gas passing through the PM detection unit and an insulator temperature of the insulator. The correction unit corrects the PM detection value detected by the PM detection unit based on at least one of the exhaust temperature and the insulator temperature.

  • Patent number: 8614893
    Abstract: An information processing apparatus allows an operator to extract temperature adjustment electrical components accommodated in two holders through a single extraction port when changing the temperature adjustment electrical components. A second holder shares a transfer pathway between an accommodation position of a first holder and an opening portion of a chassis. When the second holder moves in the direction of the opening portion, the first holder is accordingly pushed and moved. Next, the first holder is fixed to a rotating member and is moved to a position above the chassis. After the second holder is discharged to the outside of the chassis, the first holder is returned to the original position.

  • Publication number: 20130298534
    Abstract: In an ordinary mode, when an abnormality diagnosis of a PM sensor attached to a downstream opening downstream of a filter is performed, the PM sensor is moved to a first upstream opening upstream of the filter, and an exhaust gas is discharged from an engine. An ECU stores a program for the abnormality diagnosis. In an abnormality diagnosis mode, the ECU diagnoses the PM sensor by comparing an output value of the PM sensor to a standard output after performing the program. The first upstream opening may be closed by a cover in the ordinary mode.

  • Patent number: 8561388
    Abstract: A detection apparatus is used to detect a failure of a particulate filter. The detection apparatus includes a PM (particulate matter) sensor, a timing estimating unit, and a failure determining unit. The PM sensor is disposed at a downstream side of the particulate filter in an exhaust passage. The PM sensor includes a pair of electrodes and detects an amount of the PM based on current passing through the PM deposited between the electrodes. The estimating unit estimates a failure-state energization timing at which the PM sensor starts to be energized due to the PM deposited between the electrodes assuming that the particulate filter has failed. The determining unit determines that the particulate filter is in a failure state when an actual energization timing of the PM sensor based on an output of the PM sensor is earlier than the failure-state energization timing estimated.

  • Publication number: 20120186230
    Abstract: A detection apparatus includes a detection unit, a control unit, a first setting unit, and a second setting unit. The detection unit is disposed in an exhaust path through which an exhaust gas flows, and detects a correlation value correlated with an amount of particulate matter (PM) attaching to an attachment element. The control unit controls a temperature of the attachment element to follow a target temperature while a regeneration process is performed to heat the attachment element so as to burn PM. The first setting unit sets the target temperature to be lower, as the amount of PM becomes larger. The second setting unit sets a completion timing of the regeneration process so that a period of the regeneration process becomes longer, as the amount of PM becomes larger or a temperature of the attachment element becomes lower while the regeneration process is performed.
