Abstract:
Methods and systems are provided for controlling exhaust emissions by adjusting an injection profile for fuel injected into an engine cylinder from a plurality of fuel injectors during engine start and crank. By splitting injection of fuel during start so that a portion of fuel is port injected and a remaining portion is direct injected as one or multiple injections, the soot load of the engine can be reduced and fuel economy can be improved.
