Abstract: A heat recovery circuit capable of handling fluid flow from a turbine exit to a heat recovery steam generator. The heat recovery circuit includes a primary exhaust line and a by-pass circuit. Included within the by-pass circuit is a pressure reducer that is capable of lowering the pressure within the by-pass circuit to below that of the pressure at the discharge of the turbine.

Abstract: In a motor vehicle having an engine with an exhaust catalyst and an oxygen sensor upstream of the catalyst and an oxygen sensor downstream of the catalyst, a method for detecting whether the catalyst has aged. Over a test block period of time, the method periodically obtains upstream data points from an oxygen sensor located upstream of the catalyst and from and oxygen sensor located downstream of the catalyst. Absolute differences are calculated between consecutive pairs of the upstream data points and the downstream data points. A ratio between the sums of absolute differences is then calculated, and the ratio is used to determine whether the catalyst has aged.

Abstract: A vehicle includes an engine that has a plurality of cylinders and that generates exhaust gas. A catalytic converter reduces harmful emissions from the exhaust gas after achieving a light off temperature. A controller is connected to the engine and the catalytic converter. The controller deactivates the cylinder(s) of the engine before the catalytic converter achieves the light off temperature if the engine is operating at idle or low load. The controller waits a first period before deactivating the cylinder(s). The controller optimizes engine operating parameters to reduce a second period that is required to achieve the light off temperature. A temperature sensor is connected to the controller and senses ambient temperature. The controller does not deactivate the cylinders if the ambient temperature is below a first predetermined temperature. The controller activates all of the cylinders if the engine is operating at high load.

Abstract: The present invention provides for a system and process for enhancing internal combustion engine aftertreatment applications by superheated fuel injection. The system includes a fuel supply upstream of a fuel injector of an aftertreatment application. The system also includes a heater for heating the fuel in the fuel supply. A temperature controller can be used to maintain the heated fuel in a liquid form. When liquid fuel in the pressurized fuel supply is heated, then upon exiting the injector the pressure of the fuel drops rapidly, resulting in atomization of the liquid. The vaporized fuel thereby produced is comprised of extremely small droplets and is elevated in temperature, which reduces the possibility of condensation on internal surfaces of the aftertreatment system. This fine droplet size and resistance to condensation enhances the NOx conversion efficiency of adsorbers. Problems related to premature aging of catalysts and fuel penalties can also be reduced.

If the operation lever is in the actuation state, the plural pressure oil energies selective recovery apparatus does not recover a pressure oil.

Abstract: In the present method, cold substances are transferred through a nozzle with moving parts. An insulating boot facilitates the method. The present method is generally suited for use in transferring cryogenic substances such as during the refueling of liquid natural gas vehicles.
