Abstract: PURPOSE: An exhaust system is provided to effectively deal with the degradation degree of catalysts by varying the fuel injection patterns of an injector. CONSTITUTION: An exhaust system comprises an exhaust line(110), a nitrogen oxides purification catalyst(130), an injector(120), and a controller(105). Exhasut gas, exhasuted from an engine, passes through the exhaust line. The nitrogen oxides purification catalyst is installed in the exhaust line and reduces nitrogen oxides. The injector eliminates the nitrogen oxides stored in the nitrogen oxides purification catalysts by separating the nitrogen oxides. The controller varies the injection patters injected from the injector by sensing the degradation degree of the nitrogen oxides purification catalyst.

Abstract: Disclosed is a method to estimate the amount of sulfur oxides emitted from an internal combustion engine, wherein the method is capable of accurately calculating the amount of the sulfur oxides flowing into a post-processing unit by estimating the concentration level of sulfur contained in various fuels used in the internal combustion engine. The disclosed method comprises: a process of operating a fuel injection unit for a predetermined time under a condition whereby an ignition key is maintained to be on before an ignition or the internal combustion engine overruns; a process of measuring time (t_on) required to start to inject fuel at a predetermined first fuel amount or greater after the fuel injection unit is operated or a time (t_off) required to start to inject the fuel at a predetermined second fuel amount or less after the operation of the fuel injection unit is finished; a step of inversely calculating the sulfur content in the fuel by applying the time (t_on) or the time (t_off) to a predetermined map (or curve); and a step of estimating the amount of the emitted sulfur oxides, generated in a combustion process, by multiplying the amount of fuel injected, which is injected into the fuel injection unit, by the inversely calculated content of sulfur.
