Abstract
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.
