ABSTRACT:
Water under pressure is delivered to an air/fuel induction passage of an internal combustion engine under control of a three-way spool valve whose water conveying passages are completely isolated from actuating air passages by dynamic elastic seals on the valve spool. The valve is spring-biased to a water bypass position and is activated by engine manifold pressure to deliver water when the engine is running.
