ABSTRACT:
A system for injecting controlled amounts of water into the fuel intake to the cylinders in proportional response to the pressure in the engine's exhaust manifold. First conduit means, preferably including an extended surface heat sink and a length of flexible, plastic tubing, communicate the exhaust manifold pressure to the upper surface of a supply of water in an enclosed container. A lower part of the container is connected by second conduit means to a point in the fuel intake system, preferably in the air inlet to the carburetor. An adjustable throttling valve is interposed in the second conduit means for selective control of the relation of water flow to exhaust manifold pressure.
