Editing Pratt & Whitney (section)

===Engine maintenance systems===
Pratt & Whitney now markets its ''Ecopower'' pressure-washing service, which uses a high-pressure water spray run through several [[nozzle]]s to clean grime and contaminants from jet engine parts, most notably turbine blades, to prevent overheating, improve engine operating efficiency and reduce fuel burn. The system collects the runoff from the washing process for appropriate disposal. The washing is accomplished at the airport tarmac in about one hour. Customers include [[United Airlines]], [[Air India]], [[Martinair]], [[Thai Airways International]], [[Virgin Atlantic]], and [[JetBlue]].<ref>Engine Washing Cuts Airline Fuel Costs, ''The Wall Street Journal'', June 11, 2008, p.
