Title: Method and apparatus for powering engine with exhaust generated steam

Patent ·
OSTI ID:5383837

An apparatus for installation in an automobile to generate steam with heat from the exhaust of an engine is provided. The steam is generated at a sufficient pressure for entry into the combustion chambers of the engine to increase the power output of the engine. The apparatus includes a water storage unit and a steam generator for generating steam with the water from the unit through transfer of heat from combusted gases in the exhaust system. The steam travels through steam inlet manifolds for entry into the combustion chambers. The entry is controlled by a cylinder injection timing valve assembly timed to the operation of the engine to enter the steam during the power stroke. A steam throttling control valve assembly is provided to throttle the steam input to the combustion chambers. A throttle proportioning control unit proportions the carburetor throttle and steam throttle assembly to the operator throttle input to provide the greatest efficiency in engine operation. The throttle proportioning control unit operates in response to the steam temperature and pressure within the steam generator. The apparatus may be adapted for use on an engine design for solely air fuel combustion with the cylinder adapter. A throttle linkage interchange unit may be provided to initiate operation of steam input only upon reaching a minimum engine temperature. An intake manifold vacuum control valve may be provided for selectively entering exhaust gases into the intake manifold of the engine to compensate for the vacuum variation due to the steam input to the combustion chamber.
