    摘要： 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.

    摘要： One embodiment includes windmilling a boost assist device by passing intake air through the boost assist device during operating modes where the device is not required to be operated (i.e., is not being actively powered). The windmilling effect will cause the boost assist device to rotate due to the windmilling effects of the air. This windmilling effect normally may not achieve full boost assist device operating speeds, but it will normally be sufficient to allow the boost assist device to avoid the high energy usage initial speed up phase of operation when the boost assist device is called upon to be actively powered. In one embodiment of the invention the windmilling conserves energy used to drive the boost assist device.

    摘要翻译： 一个实施例包括在不需要操作装置的操作模式（即，不被主动供电）的情况下，通过使进气通过升压辅助装置来对增压辅助装置进行风车。 由于空气的风车效应，风车的作用将导致升压辅助装置旋转。 这种风力发电效果通常可能不能实现全升高辅助装置的运行速度，但是当升压辅助装置被要求主动动力时，通常足以允许升压辅助装置避免高能量使用初始加速运行阶段 。 在本发明的一个实施例中，风力发电节省用于驱动升压辅助装置的能量。

    摘要： 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.

    摘要： A method of controlling exhaust gas recirculation (EGR) in a turbocharged compression-ignition engine system including an engine, an induction subsystem in upstream communication with the engine, an exhaust subsystem in downstream communication with the engine, a high pressure EGR path between the exhaust and induction subsystems upstream of a turbocharger turbine and downstream of a turbocharger compressor, and a low pressure EGR path between the exhaust and induction subsystems downstream of the turbocharger turbine and upstream of the turbocharger compressor. A target total EGR fraction for compliance with exhaust emissions criteria is determined, then a target HP/LP EGR ratio is determined to optimize other engine system criteria within the constraints of the determined target total EGR fraction.
