  • Publication number: 20200340380
    Abstract: An exhaust gas control apparatus includes an SCR catalyst arranged in an exhaust passage, a heating device that heats the SCR catalyst, a urea solution supply device that supplies a urea solution to an upstream side of the SCR catalyst, a controller that operates the heating device and the urea solution supply device, and at least one sensor that acquires information related to a state of the exhaust gas control apparatus. The controller executes a state determination process for determining whether the exhaust gas control apparatus is currently in a predetermined state in which ammonia is not adsorbable on the SCR catalyst based on the information from the at least one sensor, and a heating avoidance process for avoiding heating the SCR catalyst with the heating device irrespective of an operating condition of the internal combustion engine when the exhaust gas control apparatus is currently in the predetermined state.
