摘要： A urea solution injection device includes an exhaust pipe for discharging exhaust gas generated in a combustion chamber to the exterior; an injector is installed and pierces into the exhaust pipe to inject urea solution into the exhaust gas flowing in the exhaust pipe. A catalyst is disposed at a position after the injector when viewed in a flow direction of the exhaust gas and the exhaust gas is discharged to the exterior to decompose the exhaust gas mixed with the urea solution. A urea solution mixer is provided at an end of the injector and installed and pierces into the exhaust pipe. Accordingly the urea solution injected from the injector is dispersed therein. An installation unit provides for the urea solution mixer to be installed in the exhaust pipe and pierces into the exhaust pipe.

摘要： A reducing agent injection device includes a honeycomb structure having a honeycomb structure body and a pair of electrode members arranged in a side surface of the honeycomb structure body and a urea spraying device spraying a urea water solution in mist form. The urea water solution sprayed from the urea spraying device is supplied inside cells from a first end face of the honeycomb structure body, and urea in the urea water solution supplied in the cells is heated and hydrolyzed inside the electrically heated honeycomb structure body to generate ammonia. The ammonia is discharged outside the honeycomb structure body from a second end face and injected outside. There is provided a reducing agent injection device that can generate and inject ammonia from a urea solution with less energy.

摘要： An exhaust system, and a catalyzed substrate, is disclosed. The system comprises a catalyzed substrate, a counterflow urea injector downstream of the catalyzed substrate, and a first selective catalytic reduction (SCR) catalyst downstream of the counterflow injector. The catalyzed substrate has an inlet end, an outlet end, an axial length extending from the inlet to the outlet, an inlet zone extending from the inlet, and an outlet zone extending from the outlet. The inlet zone comprises an oxidation catalyst and the outlet zone comprises a catalyst selected from the group consisting of a urea hydrolysis catalyst and a second SCR catalyst. The counterflow urea injector directs urea toward the outlet zone of the catalyzed substrate so that at least a portion of the urea contacts the outlet zone prior to contacting the first SCR catalyst.

摘要： Disclosed is a urea solution reformer and an exhaust gas purifier using the same, configured to heat a carrier gas supplied from a carrier gas source by a carrier gas heating unit (16), to inject the carrier gas heated by the carrier gas heating unit from a carrier gas injecting nozzle (17), and to cause a urea solution (18) to be supplied by a first urea solution supply nozzle (21) to a tip end of the carrier gas injecting nozzle so that the urea solution is atomized by the carrier gas injected from the carrier gas injecting nozzle. Provided to face toward the carrier gas injecting nozzle is a catalyst unit (23) for decomposing the atomized urea solution to reform it into an ammonia gas. Further provided is an ammonia gas supply nozzle (24) attached to an exhaust pipe (12) of an engine so as to supply the ammonia gas discharged from an outlet of the catalyst unit into the exhaust pipe. The urea solution is sufficiently atomized, and thus reformed into an ammonia gas by the catalyst unit with a good efficiency.
