  • Injection system with an emergency operation function and an associated emergency operation method
    Patent number: 6948480
    Abstract: An injection system for an internal combustion engine comprises a pump (1), a pressure accumulator (3), a sensor (7) for detecting the pressure in the pressure accumulator (3), a control valve (2) and a control or regulation unit (8). The control or regulation unit controls the pressure in the pressure accumulator (3) by opening or closing a connection to a low-pressure area (6). The control or regulation unit has an emergency operation function, which operates in such a way that when an error occurs in the regulator circuit, the control valve adopts the open position.
