<p>An object is to reduce man-hours for evaluations of design, test, and the like for securing an exhaust gas purifier 2 to an engine 1, while also making the exhaust gas purifier 2 more compact. The exhaust gas purifier 2 includes a plurality of filter bodies 43 and 44 to purify exhaust gas discharged from the engine 1, a purification casing 40 including a plurality of purification cases 46 to 49 that house the filter bodies 43 and 44, an exhaust gas pressure sensor 81 to detect an exhaust gas pressure in the purification casing 40, and an exhaust gas temperature sensor 82 to detect an exhaust gas temperature in the purification casing 40. The two sensors 81 and 82 are disposed on the outer circumferential side of the purification casing 40 so as to fit in the length range in the purification casing 40 in the exhaust gas flow direction.</p> |
