Abstract (en)
[origin: WO2011047833A1] The invention relates to a method for the open-loop control and the closed-loop control of an internal combustion engine (1), the rail pressure (pCR) being controlled in a closed loop mode in the normal operating state and an emergency operation mode being activated once a defective rail pressure sensor (9) is detected, in which emergency operation the rail pressure (pCR) is controlled in an open loop mode. The invention is characterized in that in the emergency operation mode, the rail pressure (pCR) is gradually increased until a passive pressure relief valve (11) is activated which redirects fuel from the rail (6) to the fuel tank (2) when it is open.
