An open-loop and closed-loop control method for an internal combustion engine (1) with a common rail injection system, in which a rail pressure (pCR) is subject to closed-loop control during normal operation. A second actual rail pressure is determined by a second filter, a load reduction is detected when the second actual rail pressure exceeds a first limit, and when a load reduction is detected, the rail pressure (pCR) is controlled by setting the PWM signal (PWM) to a PWM value that is increased compared to normal operation by a PWM assignment unit.
