<p>In a control device 13 for an internal combustion engine includes an intake valve, a variable valve mechanism 9 capable of controlling a closing timing and an operating angle of an intake valve 7 continuously and variably, a detection unit B60 for detecting a possibility of pre-ignition, and a throttle 15 for controlling an intake air amount such that when the possibility of pre-ignition is detected, the intake valve closing timing is retarded from bottom dead center by increasing the intake valve operating angle, the control device 13 includes, an operating angle upper limit limiting value calculation unit B55 that calculates an operating angle upper limit limiting value for limiting an upper limit value of the intake valve operating angle, and a throttle opening upper limit limiting value calculation unit B61 that calculates a throttle opening upper limit limiting value for limiting an upper limit value of a throttle opening on the basis of the intake valve operating angle.</p> |
