ABSTRACT:
Apparatus for injecting controlled amounts of water vapor into an internal combustion engine includes a water receptacle and conduit connecting the receptacle at a level above the water level therein to the intake manifold of the engine. An air inlet is also provided in the receptacle and a conduit extends from the air inlet into the receptacle below the water level. A third conduit bleeds exhaust gas from the exhaust system into the water receptacle to influence the rate at which water vapor is withdrawn from the water receptacle and conducted to the intake manifold such that at increased engine outputs the rate of water vapor injection is increased whereas at lower engine outputs the rate of water vapor injection is decreased.
