PROBLEM TO BE SOLVED: To solve a problem in which when a charged amount of a storage battery is small, a time for raising temperature of a heating part to a target temperature becomes long or the temperature cannot be raised completely.SOLUTION: An operation control device of an internal combustion engine according to this invention sets temperature of a heating part 28a of ignition means 28 to be a preheat temperature Twhen it is determined that an exhaust emission control device 26 requires warming-up and a charged amount of a storage battery 29 is a first charged amount Vor more. On the other hand, when it is determined that the internal combustion engine is in an operation state in which fuel should be supplied from a fuel addition valve 27 into an exhaust passage 23a, be ignited and combusted by the ignition means and the charged amount of the storage battery is equal to or more than a second charged amount Vor more which is larger than the first charged amount, the operation control device sets the temperature of the heating part of the ignition means to be an ignition temperature T. However, when it is determined that the charged amount of the storage battery is smaller than the second charged amount and an operation duration time of an accessory 30 is longer than a preset period while the temperature of the heating part of the ignition means is set to be the preheat temperature, the operation control device stops energization to the heating part of the ignition means. |
