Abstract
A steam assisted, optional dual drive internal combustion engine with cylinders containing a piston, where the region above a piston is a combustion chamber and a region below a piston is a water injection chamber. The engine generally has a single intake/exhaust valve in the combustion chamber, and an exhaust valve in said water injection chamber. A water injector in the water injection chamber injects water during a compression stroke of the piston which immediately vaporizes to become steam providing an upward second power stroke per cycle. The engine can have an EGR chamber with a regulator to admit a measured exhaust gas recirculation into the combustion chamber on the intake stroke, and it can utilize intake-exhaust heat exchange to pre-heat the intake mixture. In an alternate embodiment, the engine can use different cylinders to separately drive the front and rear wheels of a vehicle so that part of the engine can be shut off when not needed.
