Method and system for water collection and usage on-board a vehicle

Abstract

Methods and systems are provided for optimizing collection, usage, and processing of water on-board a vehicle. Water is harvested from various locations of the vehicle including from engine operation,surface condensation, and via dehumidification. Water is processed differently based on the source of the water as well as the intended use.

Description

technical field [0001] The present invention generally relates to methods and systems for controlling the collection, treatment and use of water on vehicles. Background technique [0002] Water may be used (eg, sprayed, sprayed, etc.) at various locations in the vehicle system to address a variety of problems. For example, water may be injected into an engine intake manifold to humidify charge air, or into an exhaust manifold to clean exhaust gases. As another example, water may be injected directly into the combustion chamber for knock control or temperature control. In further examples, water may be sprayed onto the surface of a vehicle component for cleaning or cooling the component (eg, windshield, camera lens, body, etc.), or to remove particulate matter. Additionally, the water can be treated (eg, filtered or distilled) to provide potable water that can be used by vehicle occupants. [0003] The dispensed water may come from a water collection system on the vehicle....

Problems solved by technology

On the other hand, if poor quality water is retained and used for injection into the cylinder, combustion stability and performance may be compromised
