摘要
Dynamic health assessment systems and methods related to monitoring fuel flow control are provided. In one embodiment, a method for controlling a system having an engine is provided. The method includes during a no-load condition of the engine, stopping fuel injection by a plurality of fuel injectors of the engine, closing a valve that is operable to control fuel flow to a fuel pump that pumps fuel to a common fuel rail, and setting a degradation condition in response to a fuel rail pressure decay rate of a fuel pressure in the common fuel rail being greater than a decay threshold after a first designated duration.
