<p>In a control device for an internal combustion engine which estimates a future cylinder inside air quantity by delaying an operation of a throttle, responsiveness of the internal combustion engine and estimation precision of the cylinder inside air quantity are made compatible with each other. A delay time td is provided in a calculation process until an instructed TA is outputted after a required KL is inputted. When calculation timing of a fuel injection quantity comes, an actual KL which is achieved in a time ahead by the delay time td from the present time is estimated by using an air response model. When a read-ahead time tfwd from the present time to closing timing of an intake valve exceeds the delay time td, a change amount of the actual KL which occurs by the time when the read-ahead time tfwd elapses from a time point when the delay time td elapses is estimated by using an air response model with a deviation between an estimated KL after td and a target KL set as a step input value.</p> |
