PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of certainly preventing the freezing of a throttle valve.SOLUTION: A control device 10 is mounted on a vehicle HVC which is provided with first piping 310 which is piping for connecting a part on an upstream side of a throttle valve 230 in intake piping 200 and a crank case 120; second piping 320 which is piping for connecting a part on a downstream side of the throttle valve 230 of the intake piping 200 and the crank case 120; and a PCV valve 330 which is a valve provided on the second piping 320, and opened/closed by the difference between pressure in the crank case 120 and pressure in the intake piping 200. When an internal combustion engine 100 is stopped, moisture reducing processing which is processing for reducing retention amount of moisture in the intake piping 200 is performed.SELECTED DRAWING: Figure 1 |
