Abstract: An EGR-mixer system may include an exhaust gas recirculation valve and a venturi mixer. The venturi mixer may be constructed and arranged to facilitate condensation of water out of exhaust gas and/or intake air entering the EGR-mixer system after which the condensate may be collected and the exhaust gas and/or intake air may flow through the EGR-mixer system.

Abstract: A number of variations may include an EGR-mixer system that may include an exhaust gas recirculation (EGR) valve and a venturi mixer. The venturi mixer may be constructed and arranged to facilitate condensation of water out of exhaust gas and/or intake air entering the EGR-mixer system.

Abstract: According to one implementation of an engine system, a power device is selectively actuated to provide energy to a storage device. Energy from the storage device is selectively provided to a boost assist device to supplement the normal energy supply to a boost device and enable an increased power output of the engine in at least certain engine or vehicle operating conditions. In one form, the power device may be a source of electrical energy and the storage device is capable of storing an electrical charge. In another form, the power device is a fluid pump and the storage device is capable of storing pressurized fluid. Various methods may be employed to control operation of the power device and energy storage in the storage device.

Abstract: The present invention is an exhaust gas recirculation (EGR) valve for an engine having an exhaust gas recirculation cooler operable for receiving exhaust gas from an exhaust, and delivering the exhaust gas to an intake. The present invention also includes an exhaust gas recirculation bypass passage operable for receiving exhaust gas from an exhaust, bypassing the exhaust gas recirculation cooler, and delivering the exhaust gas to an intake, as well as a single valve operably associated with the exhaust gas recirculation cooler and the exhaust gas recirculation bypass passage. The single valve is selectively operable for opening or closing flow from the exhaust to the exhaust gas recirculation cooler, the exhaust gas recirculation bypass passage, or both, the single valve also operable for metering flow therebetween.

Abstract: Mechanical systems having anti-stick mediums applied thereto are provided. In one aspect, exhaust gas recirculation (EGR) valve systems having anti-stick mediums applied thereto are also provided. The anti-stick medium can be applied to any contacting surface, such as but not limited to the valve surface and/or the valve seat surface. The anti-stick medium is intended to prevent the valve surface and the valve seat surface sticking or bonding together, especially with respect to the operation of cooled or cold side EGR systems. If any materials should stick to the anti-stick medium, a portion of the anti-stick medium will break away from the surface, allowing the surface and/or component to function normally. The anti-stick medium can include, without limitation, boron nitride coatings, boron nitride aerosols, boron nitride greases, thin dense chrome platings, perfluoroalkoxy, and combinations thereof.
