Abstract: An exhaust gas turbine powered electric generating system for supplying electrical loads on a motor vehicle. The inlet of the gas turbine is supplied with the exhaust gas of an internal combustion engine. The effective turbine inlet area is controlled by a valve which is adjusted as a function of the output current of the generator. As generator output current increases the valve is adjusted to decrease turbine inlet area thereby increasing engine back pressure which tends to slow the engine down. An idle speed control is provided which in response to engine slow-down increases the amount of air and fuel supplied to the engine to thereby increase the exhaust gas mass flow supplied to the turbine.

Abstract: A fluidic variable swirl port for an internal combustion engine includes a curved entry chamber centered on the valve axis with an inlet duct extending from one side. A small control port opens laterally into one or both sides of the inlet duct through which air or exhaust gas may be admitted to offset the path of the main inlet flow stream and generate swirl in the connecting engine cylinder when the control port is open while allowing free flow at higher flow rates when the control port is closed. Alternate embodiments and an engine operating system are also disclosed.

Abstract: A jet ignition engine, of the type in which lean mixtures in the main combustion chambers are ignited by flame jets formed by combustion of rich mixtures in adjacent small auxiliary precombustion or ignition chambers connected with the main chambers by restricted orifices, wherein the engine is provided with a main fuel system for supplying lean mixtures to the main chambers and a supplemental fuel injection system for adding fuel to the auxiliary prechambers to augment lean mixtures delivered from the main chambers and form the rich prechamber ignition charges. The simplified injection system injects fuel at low pressure during the piston exhaust strokes through timed injection valves and nozzles. Each fuel stream is directed to engage an extended spark plug electrode that forms an atomizing projection in the prechamber to break up the fuel stream, directing droplets to prechamber walls, formed by an insulated cup, for vaporization.

Abstract: An internal combustion engine is provided with a turbosupercharger including a vaned rotatable compressor wheel arranged in an inlet passage to compress inlet mixture for delivery to the engine combustion chamber, a vaned turbine wheel arranged in an exhaust passage to be driven by the flow of engine exhaust gases, a shaft interconnecting the turbine and compressor wheels for rotation together on a common axis, and vaporizable fluid heat transfer means in the form of a heat pipe extending through the shaft between the turbine and compressor wheels for transferring exhaust heat from the turbine wheel to the compressor wheel to heat the engine inlet mixture.
