| 发明名称 | System and method for lubricating a fuel pump | ||
| 摘要 | Systems and methods for diagnosing and operating an engine with a fuel pump that supplies fuel to a fuel injector that may be temporarily deactivated are described. In one example, injection of fuel may commence in response to a level of lubrication of a fuel pump. The system and methods may extend fuel pump life in systems where fuel injection may be deactivated. | ||

| 主权项 | 1. A method for operating a fuel pump, comprising: driving a motive force component of the fuel pump for supplying fuel solely mechanically; displacing the fuel from a stationary component of the fuel pump with the motive force component; wherein the stationary component is used to house the motive force component; controlling a quantity of the fuel supplied with a controller; determining the operation of the fuel pump with the controller in response to an electrical resistance measured within the fuel pump directly between the motive force component and the stationary component of the fuel pump; wherein an electric insulator is provided on an exterior surface of the motive force component and radially adjacent an interior surface of the stationary component; and indicating, via the controller, degradation of the fuel pump in response to the electrical resistance measured through the insulator of the fuel pump being less than a threshold value. | ||
