METHOD AND APPARATUS FOR DYNAMIC SURFACE CONTROL OF A PIEZOELECTRIC FUEL INJECTOR DURING RATE SHAPING |
| 摘要 |
A system and method are provided for monitoring a pressure of fuel supplied to the fuel injector, and providing a control input voltage to the piezostack in response to the pressure to cause the injector to provide a fuel injection having a desired shape. In the system and method, providing a control input voltage includes applying a model-based algorithm to the pressure to determine the control input voltage. |

1. A method, comprising:
monitoring a pressure of fuel supplied to a fuel injector of an engine; and providing a control input voltage to a piezostack of the fuel injector in response to the pressure to cause the injector to provide a fuel injection having a desired shape; wherein providing a control input voltage includes applying a model-based algorithm to the pressure to determine the control input voltage. |
