Abstract
Methods and systems are presented for adjusting an amount of fuel supplied to an engine via port and direct fuel injectors during transient engine operating conditions where the fuel injection amount is adjusted responsive to the transient engine operating conditions. In one example, a fuel injection amount is adjusted based on a time constant for a filter that is based on a direct fuel injection fuel fraction.
