Abstract
Methods and systems are provided for reducing coking deposits in a fuel injection system. In one example, a method may comprise humidifying intake air of an intake system of an engine in response to a determination that fuel injector coking is occurring, or after a duration has passed since a most recent humidification event. A humidifying fluid, such as water, may be injected into the intake system to humidify the intake air, and the resulting humidified intake air may reduce and/or remove coking deposits on one or more direct fuel injectors of the fuel injection system.
