<p>PROBLEM TO BE SOLVED: To provide a desulfurizing method of an exhaust gas post-treatment system in an internal combustion engine.SOLUTION: A desulfurizing method of an exhaust gas post-treatment system in an internal combustion engine, includes a step for checking the exhaust gas post-treatment system through measurement of at least one indicative parameter with respect to existence of sulfate, a step for additionally or alternatively grasping at least one parameter relating to production of sulfate in a region of the exhaust gas post-treatment system, and confirming whether the parameter value is within a range causing the production of sulfate or not, and a step for making emission of the internal combustion engine adapt to desulfurization in the exhaust gas post-treatment system, and/or escaping of the parameter value from the range causing the production of sulfate, by taking measures inside of the internal combustion engine or after the internal combustion engine, when it is confirmed that the sulfate exists, and/or the value of the parameter is within the range.</p> |
