  "textContent": "Emission control means of an exhaust purifying apparatus supplies fuel to exhaust gas through an exhaust passage, thereby setting the temperature of a catalyst to a temperature at which sulfur oxides occluded by the catalyst can be emitted. Based on change in an occlusion amount of sulfur oxides in the catalyst, judging means judges whether emission of the sulfur oxides from the catalyst is stagnating. When the judging means judges that emission of sulfur oxides from the catalyst is stagnating, suspending means suspends supply of fuel to exhaust gas performed by the control means. Therefore, the wasteful supply of fuel to exhaust gas is prevented, and the deterioration of fuel consumption is suppressed.",
