Abstract

An integrated internal combustion/steam engine (1), comprising a conventional internal combustion configuration and including at least one water injector (62) in each cylinder capable of supplying a predetermined volume of water into the combustion chamber (22) just after ignition and combustion of the fuel/air mixture therein. The heat of the combustion gases converts water into steam, which increases the pressure in the combustion chamber at the beginning of the power stroke, thus increasing the power output of the engine as compared with a conventional engine of similar specifications. The temperature of the gases in the combustion chamber is reduced, resulting in a comparatively cooler exhaust and requiring less engine cooling as compared with a conventional internal combustion engine of similar power output.
