摘要： An exhaust gas purifier including an NOx catalyst of the selective reduction type and a diesel particulate filter arranged in series, and being disposed in an exhaust passage of an internal combustion engine. The purifier includes a passage for urea supply having a hydrolysis catalyst therein and a passage for hydrocarbon supply having an oxidation catalyst therein. The passages are parallel to each other and separate on an upstream side of both the NOx catalyst and the diesel particulate filter. A urea feeder which supplies urea to the passage for urea supply and a hydrocarbon feeder supplies hydrocarbon to the passage for hydrocarbon supply. The injection of an urea is thereby reconciled with the direction injection of hydrocarbon into the exhaust pipe in a compact space.

摘要： When the operating state of an internal combustion engine (10) is under low load, the supply of unburned fuel is controlled by using post-injection without using in-exhaust-pipe direct injection. Under medium load, the supply of the unburned fuel is controlled by using both the post-injection and the in-exhaust-pipe direct injection. Under high load, the supply of the unburned fuel is controlled by using the in-exhaust-pipe direct injection without using the post-injection. Thus, in air-fuel ratio rich control performed during regeneration to recover the purification capability of an exhaust gas purification apparatus, both black smoke and white smoke are reduced when the supply of the unburned fuel for supplying the unburned fuel into exhaust gas is controlled.
摘要翻译：当内燃机（10）的运转状态为低负载时，通过使用后喷射而不使用排气管直接喷射来控制未燃烧燃料的供给。在中等载荷下，通过使用后喷射和排气管直接喷射来控制未燃燃料的供应。在高负载下，通过使用排气管直接喷射而不使用后喷射来控制未燃燃料的供应。因此，在再生期间进行的空燃比丰富的控制中，为了回收排气净化装置的净化能力，当向未燃烧的燃料供给未燃燃料供给到排气中时，黑烟和白烟两者都被减少。
