<p>PROBLEM TO BE SOLVED: To curb or avoid a problem with degradation of restart ability of an internal combustion engine due to a back-flow of exhaust into an intake passage while the internal combustion engine is stopped.SOLUTION: A control device of an internal combustion engine adjusts electric voltage applied to an electric motor or a magnitude of electric current when restarting the internal combustion engine depending on a quantity of at least one of the followings: a flow rate of exhaust gas flowing adversely from an exhaust passage to an intake passage during a period from a stop of an internal combustion engine to a restart thereof; a concentration of the exhaust gas flowing adversely from the exhaust passage to the intake passage and stagnating in the intake passage during the period from the stop of the internal combustion engine to the restart thereof; and a substitute value to estimate the flow rate or the concentration of the exhaust gas flowing adversely from the exhaust passage to the intake passage during the period from the stop of the internal combustion engine to the restart thereof.</p> |
