摘要： A reducing agent aqueous solution mixing device includes an exhaust pipe, an injector, a mixing pipe and an inner pipe. The exhaust pipe includes an elbow part having a curved portion, and a linear part disposed on the downstream side of the elbow part. The injector is disposed outside the curved portion and injects the reducing agent aqueous solution towards the linear part. The mixing pipe is disposed inside the elbow part to enclose a surrounding of the reducing agent aqueous solution injected from the injector, and includes a plurality of openings on an outer peripheral surface thereof. The inner pipe is disposed on the downstream side of the mixing pipe and spaced apart from an outlet portion of the mixing pipe and from an inner wall of the linear part, and allows the exhaust gas to flow through the inside thereof and the outer periphery thereof.

摘要： A reducing agent aqueous solution mixing device includes an exhaust pipe, an injector, an inner pipe and a tubular guide member. The exhaust pipe includes an elbow part having a curved portion, and a linear part disposed downstream of the elbow part. The injector is disposed outside of the curved portion, and injects a reducing agent aqueous solution into the elbow part towards the linear part. The inner pipe is disposed downstream of the injector within the exhaust pipe. The inner pipe has an inlet portion opening facing the injector and an outer peripheral surface spaced apart from the inner wall of the linear part. The inner pipe allows the exhaust gas to flow through the inside of the inner pipe and along the outer periphery of the inner pipe. The tubular guide member directs the reducing agent aqueous solution injected from the injector to the inner pipe.

摘要： An engine fuel supply system is provided at a reduced cost by using a HC dosing pump that supplies fuel into an exhaust pipe also as a pump for a cylinder fuel supply device. When a signal is generated to command air removal from a cylinder fuel supply passage, the dual-purpose pump is activated, a first on-off valve assumes an open state, and a second on-off valve assumes a close state, so that the fuel is supplied from the dual-purpose pump to the cylinder fuel supply passage via an air-removal fuel supply passage. When a signal is generated to command fuel supply into the exhaust pipe, the dual-purpose pump is activated, the second on-off valve assumes the open state, and the first on-off valve assumes the close state, so that the fuel is supplied from the dual-purpose pump to the exhaust pipe via the exhaust-pipe fuel supply passage.
