ABSTRACT:
A steam injection apparatus for an internal combustion engine having an exhaust system, a carburetor and an engine vacuum line, the apparatus including a reservoir of liquid water, a conduit communicating with the reservoir and a heater coil of metallic tubing. The heater coil has an inlet which communicates with the conduit and an outlet which communicates with the vacuum line. The coil is placed in heat-receiving relation to the engine exhaust system for heating water in the coil. The coil has a cross-section that is insufficient to allow complete vaporization of the water in the coil, and the water is substantially vaporized within the vacuum line for introduction into the engine in a vaporized state. An air inlet is connected to the conduit at a tee fitting for mixing air with water from the reservoir for regulating flow to the heater coil. A threaded member is placed within resilient tubing, and provides an air passage through its threads and restricts air flow through the tubing. A clamp compresses the resilient tubing about the threaded member for regulating flow through the air passage. The coil is flexibly shapeable to provide contours for substantial heat transfer contact with the exhaust system.
