Abstract
Methods and systems are provided for adjusting engine operation based on estimated vaporized and condensed portions of water injected during a water injection event. In one example, a method may include injecting an amount of water into the intake manifold in response to engine conditions and inferring vaporized and condensed portions of the injected water based on the injected amount and a change in manifold temperature following the injection. Further, the method may include adjusting water injection and engine operating parameters in response the evaporated and/or condensed portion of water.
