发明名称 METHOD FOR THE CLOSED-LOOP CONTROL OF THE RAIL PRESSURE IN A COMMON-RAIL INJECTIOM SYSTEM OF AN INTERNAL COMBUSTION ENGINE
摘要 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).
