摘要： The present invention is intended to provide a technique which is capable of improving detection accuracy at the time of performing failure detection of a particulate filter by the use of a PM sensor. In the present invention, the PM sensor is arranged in an exhaust passage at the downstream side of the particulate filter. Then, the presence or absence of a failure in the particulate filter is determined by making a comparison between an output value of the PM sensor at the time when a predetermined period of time has elapsed after the execution of PM removal processing to remove the particulate matter deposited on the PM sensor is completed, and a predetermined threshold value. At this time, the threshold value is set based on an average value of an amount of intake air in an internal combustion engine during the passage of the predetermined period of time.

摘要： The present invention has an object to prevent a short-circuit between a heat generation element, which is electrically energized to generate heat, and a case in an electrically heated type exhaust gas purification apparatus. In order to achieve this object, the present invention is constructed such that a laminated body composed of a holding member and an inner cylinder is arranged between a heat generation element, which is electrically energized to generate heat, and a case which covers the heat generation element, and the inner cylinder has an upstream side end portion extended to a more upstream side than an upstream side end face of said heat generation element and an upstream side end face of said holding member to form an extension portion, which is formed with a protruding portion protruding to an inner side in a diametrical direction. A flow of an exhaust gas, which flows backwards after colliding with the heat generation element, will be obstructed by said protruding portion. As a result, the backflow exhaust gas stops flowing into a gap between the case and the inner cylinder. Therefore, a drop in insulation, resulting from an inner peripheral surface of the case, an upstream side end face of the holding member, and an outer peripheral surface of the inner cylinder being covered with particulate matter, is suppressed.
