Abstract

A marine propulsion system is provided with a pump, a filter, and a water injector for injecting a spray or mist of water into the charge air of an internal combustion engine. Water is drawn from a body of water in which a marine propulsion system is operated, in conjunction with a marine vessel, and the water is pumped through a filter before being injected into the charge air of the engine. The filter can be a reverse osmosis device. The engine can be a turbo-charged or normally aspirated engine. The water injection system is suitable for use in association with the 4-cycle or 2-cycle engines.
