Abstract: Partial denitrations are made practical by an SCR catalyst placed downstream of a NOx adsorber. The SCR catalyst permits partial denitrations to be extended to where a favorable fuel penalty rate presented by driving conditions can be utilized to a sufficient extent that the benefit of the favorable conditions is not offset by the increased start-up fuel penalty associated with conducting opportunistic partial denitrations. Regenerations, including both denitration and desulfations, can be initiated selectively based on a fuel penalty calculation. Examples of such calculations lead to methods in which opportunistic regenerations are based on low oxygen concentrations, condition existing while shifting gears, and throttling events for a diesel engine with a throttled air supply. The methods flexibly take advantage of driving conditions to reduce fuel penalties associated with regenerations. In one embodiment, driving conditions include future conditions predicted based on GPS and map data.

Abstract: A novel method converts heat into mechanical work. In a cyclic process, a working medium is compressed while giving off heat and it is subsequently brought in thermal contact with the surroundings via a first heat exchanger. Then it is expanded while obtaining mechanical work, whereupon the cyclic process is run through once more. A high degree of efficiency is achieved by virtue of the fact that the working medium, after expansion, is guided through another heat exchanger, which is situated inside a rapidly rotating rotor and which, on the exterior thereof, is surrounded by at least one substantially annular gas space from whose exterior heat is dissipated. There is also disclosed a device for carrying out the novel method.

Abstract: The present invention is directed to a turbine seal system. The turbine seal system captures working fluid which is escaping from a closed loop thermodynamic cycle system, condenses the captured working fluid, and returns the condensate back to the thermodynamic cycle system. The turbine seal system is configured to apply nitrogen, or other non-condensable, or other material, to capture or mix with the escaping working fluid. The combined mixture of working fluid which escapes the turbine and the nitrogen utilized to capture the working fluid is evacuated by an exhaust compressor which maintains a desired vacuum in a gland seal compartment of the turbine seal. The combined mixture can then be sent to a condenser to condense the working fluid vapor and evacuate the non-condensables, forming a working stream. Once the non-condensables have been evacuated, the working stream is pumped to a higher pressure, and prepared to be re-introduced into the thermodynamic cycle system.

Abstract: The filed application is a supplement to my U.S. application Ser. No. 10/757,596 and to my German application No.: 103 02 041.1-13, which represent a basic conception for a novel internal combustion engine with the name: Injector-Centrifuge-Turbine-Engine (ICT-Engine) for road vehicles, and injector-Centrifuge-Jet-Engine (ICJ-Engine) for aircraft. New is the introduction of a supersonic injector in place of the turbine and the rotary compressor, and the introduction of a gas-centrifuge for decomposing of the mixed gases. In particular for aircraft, our presently used turbine-engines suffer from fatal turbine-blades crackings, which often results in aircraft crashes, with hundreds of burnt people. This can be eliminated by the novel engine. But also the automobilists would have a profit, by ca. 30% reduction in fuel consumption, arising from removal of the engine cooling and engine friction.
