Abstract: PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of promptly supplying the amount of vaporized fuel necessary for ignition to the inside of a cylinder even at low-temperature start and of improving startability.SOLUTION: An ECU 60 determines whether or not a stop request to the engine is made (Step 106). When it is determined that the engine stop request is made, the ECU 60 determines whether or not remaining vaporized fuel amount Qg is Qgmin or less (Step 108). When the remaining vaporized fuel amount Qg is the start permission vaporized fuel amount Qgmin or less, the ECU 60 determines that gas fuel amount is run short of, and continues the operation of the engine until a vaporized fuel tank temperature Tgt gets to a generation permission temperature T1 or more (Step 110). Fuel of an injection amount equivalent to combination of the vaporized fuel tank temperature Tgt after elevation and alcohol concentration Cal is injected to the inside of a vaporized fuel tank 34 (Step 112).

Abstract: PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine, improving the startability by promptly supplying vaporized fuel of a desired concentration even in starting at a low temperature.SOLUTION: In vaporized fuel generation control for generating the vaporized fuel in a vaporized fuel tank 38 during operation of an engine 10, an injection amount Q is calculated so that all injected fuel evaporates and vapor pressure of the vaporized fuel becomes a saturated vapor pressure (steps 106-108), and the fuel is injected from a tank injection valve 40 (step 114). At this time, pressure in the vaporized fuel tank 38 is reduced to a target pressure P1 before injection of the fuel (steps 110-112). The target pressure P1 is calculated as a pressure value in the vaporized fuel tank 38 for allowing a ratio of residual air in a space from the vaporized fuel tank 38 to a combustion chamber (the space formed in the vaporized fuel tank 38, a surge tank 20, an intake manifold 22 and an intake port 24) to the fuel injection amount Q to become a predetermined ratio.

Abstract: PROBLEM TO BE SOLVED: To suppress execution of rotation reduction preventing control along with reduction of a target rotation speed during a travel stopping process of a vehicle, and to avoid difficulty for quickly performing travel stop of the vehicle caused by sudden rise of an engine rotation speed due to the rotation reduction preventing control. SOLUTION: When an engine 1 shifts to idling operation in the travel stopping process of an automobile, the target rotation speed of idling rotation speed control is reduced only under a condition that a road surface has low friction coefficient, and a determination speed of the rotation reduction preventing control is also reduced along with the reduction of the target rotation speed. When an engine rotation speed is reduced along with the reduction of the target rotation speed thereby, the engine rotation speed is reduced by action of disturbance in an rotation stop direction to a driving wheel 6 (such as frictional force from a road surface side). The engine rotation speed is restrained from being equal to or lower than the determination rotation speed. Accordingly, when the target rotation speed is reduced during the travel stopping process of the automobile, the execution of the rotation reduction preventing control is restrained in association therewith.
