Apparatus and method for driving a piezoelectrically controlled fuel injection valve |
摘要 |
An apparatus for driving a piezoelectrically controlled fuel injection valve includes a piezoelectric actuator having a discharging device and preferably a power MOSFET switch connected in parallel therewith. The discharging device is turned on by a monitoring device that is likewise connected in parallel with the piezoelectric actuator if an opening time of the piezoelectric actuator exceeds a predetermined monitoring time. The discharging device and the monitoring device are constructed as an integrated circuit (ASIC) and are integrated in a valve housing. A method for operating the apparatus is also provided.
