Abstract
Methods and systems are provided for controlling fuel injectors for a fuel system configured to deliver fuel to an engine via each of port fuel injection and direct fuel injection. In one example, a method may include, during an engine green start condition, injecting fuel with the port injector while not injecting fuel with the direct injector, and after the green start condition, injecting with each of the port injector and the direct fuel injector at a fuel ratio determined based on engine operating conditions.
