Abstract
Methods and systems are provided for assessing the quality of water in a water injection system using existing engine sensors. A change in manifold charge temperature following a water injection may be compared to a change in intake oxygen level to determine an error between an amount of water delivered to the engine and an amount of water actually used in the engine. The error may be correlated with the water quality and used for correcting subsequent water injection commands.
