Abstract

Disclosed is a method for controlling an injection amount of fuel of a burner and an aftertreating device of exhaust gas, and more particularly, to a method for controlling an injection amount of fuel of a burner and an aftertreating device of exhaust gas, in which the burner is controlled in consideration of exothermic effect due to a catalytic filter, thereby stably reducing exhaust gas.

Description

TECHNICAL FIELD[0001]The present invention relates to a method for controlling an injection amount of fuel of a burner and an aftertreating device of exhaust gas, and more particularly, to a method for controlling an injection amount of fuel of a burner and an aftertreating device of exhaust gas, in which the burner is controlled in consideration of exothermic effect due to a catalytic filter, thereby stably reducing exhaust gas.BACKGROUND ART[0002]In general, since a diesel engine has higher power and lower fuel expenses than a gasoline engine, it is widely applied to vehicles, construction equipments, ships and the like.[0003]However, the diesel engine is a four-stroke engine in which fuel is injected into the engine and then burnt in a compression ignition method, and in a self-ignition process of the fuel, incomplete combustion occurs due to non-uniformity of a fuel-air ratio, and thus noxious particle (exhaust gas) is generated.[0004]Particularly, the noxious particle mainly co...
