Abstract
A method for closed-loop control and open-loop control of an internal combustion engine having a common rail system is closed. In the proposed method, the rail pressure (pCR) is determined in that an electronic engine control unit specifies the flow rate of a high-pressure pump into the rail via an intake throttle on the low-pressure side. An intake throttle actuation function, by which the intake throttle is temporarily actuated, is set to recur over time in the case of known idle time of the internal combustion engine and an actuated engine control unit.
