APPARATUS FOR PURIFYING EXHAUST GAS FOR AN INTERNAL COMBUSTION ENGINE |
| abstract |
In order to simplify an exhaust gas emission purification apparatus using carbamide powder as a reducing agent and, to reduce its dimensions, carbamide powder A received in a reducing agent reservoir chamber 12 of a device addition of reducing agent 11 is heated and liquefied in a heating / liquefaction chamber 13 to become liquid carbamide. Liquid carbamide is pressurized in a pump section 14, pressure adjusted to a constant pressure level in a pressure regulating section 15, and is added from an addition control valve 16 to a supply line. exhaust 7. The liquid carbamide added to the exhaust pipe 7 is immediately gasified to become reducing gas by the heat of the exhaust gas and introduced into a NOx catalysis converter 8 with the exhaust gas. The reducing gas reduces NOx by the selective reduction type Nox catalysis received in the NOx catalysis converter 8. |
