The application relates to a method and system for selecting a position for water injection in an engine. Methods and systems are provided for selecting a position for water injection based on engineoperating conditions during a water injection event. In one example, a method may include selecting a position for water injection from one of an intake port of each cylinder, an intake manifold upstream of all engine cylinders and directly each of the cylinders based on engine operating conditions. Further, the method may include adjusting water injection and engine operating parameters in response to the evaporated and/or condensed portion of water.
