Methods and systems are provided for improving engine start roughness. In one example, a method for reducing engine start NVH includes operating the engine with a split fuel injection while advancing injection timing as engine coolant temperature increases. The method allows for a smoother engine start while also reducing false misfire incidences.

Method and system for engine cold-start control

Methods and a system are provided for controlling fuel injection in a vehicle engine. The system specifically relates to an engine fueled with both port and direct fuel injectors. In one example, a method may include delivering a first portion of fuel via port injection during a first injection window, and subsequently delivering a second portion of fuel directly during a second injection window before the engine exits cranking speeds.

Methods and systems for dual fuel injection

A method is disclosed for controlling engine output in a vehicle having a hydraulic power steering system. The method may include, during an idle condition where an engine speed is set to an idle speed, adjusting engine output based on a learned absolute steering wheel angle to compensate for changes in engine load caused by operation of the hydraulic power steering system. The learned absolute steering wheel angle may be based on a steering wheel angle relative to a steering wheel position at vehicle startup and operating conditions from previous vehicle operation before the vehicle startup.
