    • A system (1 OA-I OE) includes a hydrogen fueled internal combustion engine (12A-12E), a fuel system configured to provide a flow of hydrogen fuel to the engine (12A-12E), and an exhaust gas recirculation (EGR) system configured to provide a flow of recirculated gas to the engine (12A-12E) which includes exhaust gases. The system (10A-10E) also includes an engine controller (25A-25E) configured to control the fuel system and the EGR system, such that the engine (12A-12E) receives a mixture which includes the hydrogen fuel, the ambient air and the recirculated gas in a stoichiometric fuel/air ratio that meets the torque demand on the engine (12A-12E). A method includes the steps of providing a flow of gaseous hydrogen fuel, a flow of ambient air, and a flow of recirculated exhaust gas to the engine (12A-12E). The method also includes the steps of mixing the flow of recirculated exhaust gas and the flow of ambient air, determining a flow of hydrogen fuel necessary to create a stoichiometric fuel/air ratio, and then regulating the hydrogen fuel flow to control the torque of the engine (12A-12E), minimize throttling work and provide a mixture comprised of the hydrogen fuel, the ambient air and the exhaust gas in a stoichiometric fuel/air ratio.
    • 一种系统(10A-10E)包括氢燃料内燃机(12A-12E),构造成向发动机(12A-12E)提供氢燃料流的燃料系统,以及构成废气再循环(EGR) 系统,其被配置为向包括排气的发动机(12A-12E)提供再循环气体流。 系统(10A-10E)还包括构造成控制燃料系统和EGR系统的发动机控制器(25A-25E),使得发动机(12A-12E)接收包括氢燃料,环境空气和 以满足发动机(12A-12E)上的扭矩需求的化学计量燃料/空气比率的再循环气体。 一种方法包括提供气态氢燃料流,环境空气流和再循环排气流到发动机(12A-12E)的步骤。 该方法还包括以下步骤:混合再循环废气流和环境空气流,确定产生化学计量燃料/空气比所需的氢燃料流量,然后调节氢燃料流量以控制 发动机(12A-12E),最小化节流功,并以化学计量的燃料/空气比提供由氢燃料,环境空气和废气组成的混合物。
