Abstract: A control apparatus and control method is provided for an internal combustion engine that includes a vaporized fuel tank in which vaporized fuel is stored, and a normally-closed vaporized fuel supply valve that opens and closes a connecting portion between the vaporized fuel tank and a surge tank. This apparatus and method produce vaporized fuel by injecting fuel into the tank while the vaporized fuel supply valve is closed while the engine is operating, then open the vaporized fuel supply valve at engine startup and supply the vaporized fuel stored in the tank to the surge tank. If there is no vaporized fuel remaining in the vaporized fuel tank when the engine stops, vacuum is generated in the vaporized fuel tank by temporarily opening the vaporized fuel supply valve before the engine stops. Vaporized fuel is then produced by injecting fuel into the vaporized fuel tank in this vacuum state.

Abstract: A cylinder air filling amount is divided into a first amount of air and a second amount of air, the first amount of air and the second amount of air are calculated, and the first amount of air and the second amount of air are totaled to calculate a cylinder air filling amount. The first amount of air is the excess of the cylinder air filling amount with respect to the throttle valve air passage amount occurring due to an intake stroke being performed. The drop in intake pressure occurring due to an intake stroke being performed is detected for each cylinder and the total value of the intake pressure drop in a 720° crank angle range is calculated. The first amount of air is calculated based on an intake pressure drop and the intake pressure drop total value. Due to this, it is possible to simply and accurately calculate a cylinder air filling amount.
