METHODS AND SYSTEMS FOR COMMON RAIL FUEL SYSTEM DYNAMIC HEALTH ASSESSMENT

摘要

Fuel control 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, includes determining a predicted valve position of a valve, the valve being operable to control fuel flow to a fuel pump that pumps fuel to a common fuel rail of the engine, determining an actual valve position, determining an error between the predicted valve position and the actual valve position, and setting a degradation condition in response to the error.
