ABSTRACT:
A common rail injection system for an internal combustion engine, wherein upon detection of a defective rail sensor system the transition from the normal operation to the emergency operation is determined reliably by means of a transition function. The transition function is determined beforehand from the characteristics of a system deviation as a function of time during normal operation. In so doing, the system deviation is calculated from a variance comparison of the rail pressure. The result of this defect transition process is a more noise-proof and more continuous transition from the normal operation to the emergency operation.
