Fuel injection system pressure sensor has ceramic layers connected to conductors for a sensor signal and a PZT (lead-zirconium-titanium) film placed over them

摘要

The pressure sensor for a fuel injection system has a number of ceramic layers and conductors for the sensor signal, whereby the ceramic layers (2) have a planar PZT (lead-zirconium-titanium) film placed over them and electrically connected to the conductors. An Independent claim is included for a fuel injection system.
