PURPOSE: An exhaust gas reducing apparatus is provided to stably maintain the temperature of exhaust gas as the flame in a second combustion chamber is rapidly ignited even in the case the flame in a first combustion chamber is extinguished. CONSTITUTION: An exhaust gas reducing apparatus comprises an exhaust pipe(100), first and second combustion units, an injection nozzle(300), first and second igniters, and an air feeder(600). The exhaust pipe delivers exhaust gas to an exhaust gas filter(F). The first combustion unit is installed inside the exhaust pipe, and placed between an engine and the exhaust gas filter. The first combustion chamber comprises a first combustion chamber(211). The injection nozzle is mounted into the first combustion unit, and injects a mixture mixed with air and fuels to the first combustion chamber. One end of the first igniter is placed inside the first combustion chamber, and ignites the mixture injected from the injection nozzle. The second combustion unit comprises a second combustion chamber(521) connected to the first combustion chamber. The air feeder supplies the air to the second combustion chamber. One end of the second igniter is placed inside the second combustion chamber. |
