Combustion and steam engine system and methods

Abstract

A combustion-and-steam engine system has a phase-change water injector (1) through which water is spray-injected into combustion gases in a combustion chamber (2) of a Nelson Engine (79) or any type of heat engine with either rotational or thrust power. A steam tube 45 in fluid communication between an injector orifice (25) and an internal periphery of the combustion chamber can be heated with resistance heat from an engine-electrical source (46) to provide phase-change of water en route to the combustion chamber in the steam tube. An injection-metering valve (22, 25, 26, 43) has a return spring (31) with pressure regulatable by an adjustment means (32, 33, 36, 37, 38, 40) to select flow rate past the injection-metering valve to a return tube (57, 74) without requiring lubricity of water or other fluid under high pressure. A phase-change fuel injector (65) has similar components with a heat tube (13) that can be shorter and bigger around to allow rapid entry of fuel-rich combustion gases into the combustion chamber ahead of steam from the phase-change water injector. Design levels of completeness of combustion of fuel are provided prior to injection of a design heat and consistency of wet steam and dissociated water. This provides a combination of designedly fuel and hydrogen combustion in combination with steam pressures from cooling a heat engine with phase-change heat absorption of water particles in the combustion chamber.
