    • A fuel injection system for an internal combustion engine is provided which works to correct the pressure of fuel, as measured by a pressure sensor, using a pressure change corresponding to a change in quantity of the fuel in a common rail within a pressure change compensating time Tp to determine a pump discharge pressure Ptop. This compensates for an error in determining the pump discharge pressure Ptop which arises from propagation of the pressure of fuel from a pump to the pressure sensor. The pressure change compensating time Tp is the sum of a time T1 elapsed between sampling the output of the pressure sensor before a calculation start time when the pump discharge pressure is to start to be calculated and the calculation start time and a time T2 required for the pressure to transmit from the outlet of the pump to the pressure sensor.

    • To reliably prevent a drop in the function of injectors resulting from a rise in the temperature of excess fuel in the injectors without having to add a new part.In a common rail fuel injection control system according to the present invention, when it is determined that an engine rotational speed Ne, a vehicle velocity V and a rail pressure exceed respective predetermined references, the count value of a determining counter is increased (steps S100 to S106), and when it is determined that the engine rotational speed Ne, the vehicle velocity V and the rail pressure do not exceed the respective predetermined references, the count value of the determining counter is decreased (steps S108 to S114), and next, when it is determined (step S116) that the count value of the determining counter exceeds a predetermined protection initiation reference Cs, limitation of the fuel injection amount and the rail pressure and correction of a smoke limit value are performed (see steps S120 to S124) until the count value of the determining counter falls below the predetermined protection initiation reference, whereby injector protection is performed.

    • 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 the normal operating state in a closed loop control mode via an intake throttle (4) on the lower pressure side as the first pressure control member in a rail pressure control loop and at the same time a rail pressure disturbance variable being applied to the rail pressure (pCR) via a pressure control valve (12) on the high pressure side as the second pressure control member. For this purpose, a pressure control valve volume flow (VDRV) is redirected from the rail (6) to a fuel tank (2) via the pressure control valve (12) on the high pressure side, and an emergency operation mode is activated once a defective rail pressure sensor (9) is detected, in which emergency operation the pressure control valve (12) on the high pressure side and the intake throttle (4) on the low pressure side are actuated depending on the same set point value.
