Abstract:
Methods and systems are provided for reducing port injection fuel errors by selectively reactivating a direct fuel injector. Responsive to an increase in driver demand received while delivering fuel to a cylinder via port injection only, wherein the increase in driver demand is received late in the port injection window, the port injection error is addressed by reactivating a direct injector on the same engine cycle and delivering at least a portion of the fuel mass corresponding to the error via the direct injector. Additionally, a portion of the fuel mass may be delivered by the port injector on the same engine cycle by extending the end of injection timing, if possible.
