| 20090212127 | FUEL INJECTOR WITH SINGLE CRYSTAL PIEZOELECTRIC ACTUATOR STACK - One embodiment includes a piezoelectric fuel injector using single crystal piezoelectric materials to improve the capabilities and performance of fuel injectors using a piezoelectric material stack. Another embodiment includes a fuel injector with a single crystal piezoelectric actuator stack that exceeds one or more of the capabilities (e.g., stroke, force, bandwidth, size) of the standard piezoceramic actuator stacks designed for the common rail fuel injector systems. Yet another embodiment includes an actuator stack made from single crystal piezoelectric material. | 08-27-2009 |
