An exhaust purification device for purifying exhaust gas flowing in an exhaust gas flow passage of an engine includes: a cylindrical casing; a pipe that is disposed on a downstream side of the casing and inserted in the casing so as to extend in a direction substantially orthogonal to an axial direction of the casing, the pipe being provided with a through-hole communicating with the casing; and an injector configured to inject a reducing agent from an upstream end of the pipe into the pipe, in which a contracting flow passage portion narrowing in an axial direction of the pipe from an upstream side toward the downstream side is formed in the exhaust gas flow passage in the casing.

Exhaust purification device

An air intake ductis fixed to a rear of a cabof a transport vehicle to extend vertically, air intakesandbeing opened on an upper portion of the air intake duct for suction of fresh air through the intakes as engine intake air. The air intake ductis constituted by a blow-molded duct bodyand an internal partition componentenclosed in the duct body in blow molding of the duct bodyto partition an interior of the duct bodyinto a plurality of channels A, B, C, D, E and F reaching the air intakes.

Air intake duct and method for producing same

An exhaust gas purification system includes an exhaust purifying element for purifying exhaust gas, and a selective reduction catalyst for promoting reduction of NOx contained in the exhaust gas with a reducing agent. A housing for accommodating the exhaust purifying element includes an outer wall having an accommodating portion. A supply hole is formed on a bottom of the accommodating portion. A pipe that is located inside the housing has a passage through which an interior of the pipe communicates with an exterior of the pipe. The pipe is configured to guide exhaust gas toward the selective reduction catalyst through the passage and the interior of the pipe. The pipe has an end communicating with the supply hole. The injection device of the exhaust gas purification system injects the reducing agent to an interior of the pipe through the supply hole.
