20120144813 | FAILURE DETECTION APPARATUS FOR PARTICULATE FILTER - 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. | 06-14-2012 |
20120186230 | DETECTION APPARATUS - 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. | 07-26-2012 |
20120186330 | DETECTION APPARATUS - 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. | 07-26-2012 |
