Abstract: The system (30) has a loading unit (14) with a turbine (18) which is arranged in an exhaust gas passage (17) for an internal-combustion engine (11). An ammonia injecting valve (31) injects an ammonia gas into an exhaust gas which flows into the passage. A reduction catalyst (36) reduces nitrogen oxide contained in the exhaust gas by the ammonia gas, where the reduction catalyst is injected through the ammonia injecting valve. The ammonia injecting valve injects the ammonia gas along an external circumference of the exhaust gas stream, after the exhaust gas stream passes through the turbine.

Abstract: The device (1) has a tank (2) for storing a liquid reducing agent, and a supply pump (3) sucking the reducing agent from the tank and supplies the reducing agent to an exhaust gas. An air pump (21) is provided for supplying air into a gaseous phase section, and a valve device (22) opens/closes a gaseous phase section to an environment. A filling device controls pressure in the phase section of the tank to fill the reducing agent inside the supply pump. A control device (10) controls an extracting device and the filling device in accordance with an operating condition of a machine.

Abstract: The valve (1) has a body (20) including two nozzle holes (11, 12) at an end section of the body. An injecting angle of the hole (11) that is closed or opened by a valve body (9) is different from an injecting angle of the hole (12) that is closed or opened by a valve body (10), under the condition that the angles are provided at a positive side, when hole axes of the nozzle holes are aligned to a downstream side in a flow direction of an exhaust gas with respect to a radial direction of an exhaust gas pipe.

Abstract: PROBLEM TO BE SOLVED: To provide a tank device collecting ammonia leaking from an ammonia reservoir, and preventing ammonia from being released to the atmosphere. SOLUTION: This tank device 30 has a double structure having an inner vessel 31 and an outer vessel 32. Ammonia is stored in the ammonia reservoir 33 formed inside of the inner vessel 31. A fluid reservoir 34 is formed between the inner vessel 31 and the outer vessel 32, and water is stored in the fluid reservoir 34. Since ammonia has extremely high solubility in water, ammonia leaked from the ammonia reservoir 33 is trapped by water stored in the fluid reservoir 34. Thereby, even if the inner vessel 31 is damaged, leaked ammonia is trapped by water stored in the fluid reservoir 34. COPYRIGHT: (C)2009,JPO&INPIT
