    摘要: An exhaust gas purification apparatus in which layout restriction is lessened to be able to further achieve space-saving is proposed. The exhaust gas purification apparatus includes a first cylindrical housing in which an oxidation catalytic converter and a PM collection filter are contained and a second cylindrical housing in which a reducing catalytic converter and an ammonia oxidation catalytic converter are contained. The exhaust gas purification apparatus further includes a communicating pipe that connects between far end portions of both the housings, and a nozzle that is disposed in the communicating pipe and injects liquid reducing agent in exhaust gas. The two housings are closely disposed such that axis lines thereof are arranged substantially parallel. The communicating pipe is disposed such that an axis line thereof is arranged substantially parallel with the axis lines of the housings. A flow passage of the exhaust gas from the first housing to the second housing is folded by the communicating pipe.

    摘要: An engine exhaust gas purification apparatus for engine includes a mixing device for promoting mixing of a liquid reducing agent or a precursor thereof and exhaust gas is disposed at a position at which, when an engine is operating in a predetermined operating state, the liquid reducing agent or the precursor thereof injection-supplied from an injection nozzle impinges on substantially an entire surface of the mixing device. The predetermined operating state may be, for example, an operating state in which a solute tends to deposit from the liquid reducing agent or the precursor thereof. Thus, the liquid reducing agent or the precursor thereof adhering to the mixing device or an exhaust passage is reduced in absolute amount, thereby preventing that only a solvent evaporates from the liquid reducing agent or the precursor thereof adhering to the mixing device or the exhaust passage to deposit the solute.
