Proposed is a method for open-loop and closed-loop control of an internal combustion engine (1), the rail pressure (pCR) being controlled via a low pressure-side suction throttle valve (4) as the first pressure-adjusting element in a rail pressure control loop. The invention is characterized in that a rail pressure disturbance variable is generated to influence the rail pressure (pCR) via a high pressure-side pressure control valve (12) as the second pressure-adjusting element, by means of which fuel is redirected from the rail (6) into a fuel tank (2).
1. A method for open-loop and closed-loop control of an internal combustion engine, comprising the steps of: controlling maximum rail pressure by a passive pressure control valve connected directly to the rail by a first independent discharge line;automatically controlling rail pressure (pCR) in a closed-loop rail pressure control system by a suction throttle on a low-pressure side as a first pressure regulator;generating a rail pressure disturbance variable (VDRV) for influencing the rail pressure (pCR) by way of a pressure control valve on a high-press...
