Abstract

A filter (6) collecting particulate matter in exhaust gas is provided in an exhaust path of an engine. A proximal thermosensor (2) and an entire-area thermosensor (3) are provided downstream of the filter (6). A position of the proximal thermosensor (2) is set to a position in proximity to a downstream end surface of the core portion (6a) in a cross-sectional surface in a radial direction of the filter (6). The proximal thermosensor (2) detects the proximal temperature of the exhaust gas that passed through the core portion (6a) of the filter (6). The entire-area thermosensor (3) detects the entire-area temperature of a mixture of a first exhaust gas stream and a second exhaust gas stream that passed, respectively, through a peripheral portion (6b) and a core portion (6a) of the filter (6). Calculating means (5) is provided for calculating a peripheral temperature of the peripheral portion (6b) of the filter based on the proximal temperature detected by the proximal thermosensor (2) and the entire-area temperature detected by the entire-area thermosensor (3).
