    摘要： An exhaust gas purifier for an internal combustion engine (10) capable of removing a deposit from an addition nozzle (32) without consuming excessive fuel is provided. The addition nozzle (32) included in the exhaust gas purifier adds fuel to exhaust gas in an exhaust passage (27, 28), which guides the exhaust gas that has been discharged from a cylinder (11, 12, 13, 14) of the engine (10). The exhaust gas purifier further includes determining means (C), temperature raising means (16-19; C, 37, 39; C, 38; C, 33), and control means (C). The determining means (C) determines whether the addition nozzle (32) is clogged. The temperature raising means is adjustable to a raised temperature adjustment state for raising the temperature of the addition nozzle (32). The control means (C) controls a temperature adjustment state of the temperature raising means such that the temperature raising means is switched to the raised temperature adjustment state when the determining means (C) determines that the addition nozzle (32) is clogged.
