FUEL INJECTION DEVICE AND EXHAUST AFTERTREATMENT APPARATUS INCLUDING THE SAME

摘要

PURPOSE: A fuel jetting apparatus and an exhaust gas post-processing system equipped with the same are provided to activate catalysts with increasing the purification efficiency. CONSTITUTION: A fuel jetting apparatus(100) comprises a housing(200), a fuel supply unit(300), an air supply unit(400), a heater unit(500), and a spraying nozzle(600). The fuel supply unit injects sprays liquid fuel to the housing by mixing the fuel with air The fuel supply unit comprise a fuel nozzle(310) and a mixing nozzle(320). The mixing nozzle is extended from the fuel nozzle, and mixes the fuel with the air. The air supply unit is connected to the fuel supply unit. The heater unit generates a mixture of vaporized gas by heating the fuel and air sprayed from the fuel supply unit. The spraying nozzle is connected to the housing to spray the mixture of gas to an exhaust pipe.
