Exhaust gas control apparatus of internal combustion engine |
摘要 |
An engine (1) is provided with a urea aqueous solution supply mechanism (200) that adds a urea aqueous solution into an exhaust passage (26), an SCR catalyst (41) that adsorbs the urea aqueous solution added from the urea aqueous supply mechanism (200), and a turbocharger (11) having a nozzle vane (11v). A control apparatus (80) increases an exhaust gas flow rate by changing an opening amount of the nozzle vane (11v) to a minimum opening amount when adding the urea aqueous solution when the engine (1) is decelerating. |
