The present disclosure describes a fuel system for an engine. The fuel system includes a fuel metering valve, a flow measuring system, and a controller in communication with the fuel metering valve and the flow measuring system. The fuel metering valve is operable to meter a flow rate of fuel based on a stroke of the fuel metering valve. The flow measuring system is configured to measure a mass flow rate of the fuel leaving the fuel system at a bandwidth greater than 20 Hz. The controller is configured to dynamically adjust the stroke of the fuel measuring system based on the mass flow rate of the fuel measured by the flow measuring system to change the flow rate of the fuel. 本公开描述了一种用于发动机的燃料系统。该燃料系统包括燃料计量阀、流量测量系统以及与燃料计量阀和流量测量系统通信的控制器。燃料计量阀可操作以基于燃料计量阀的冲程来计量燃料的流率。流量测量系统被配置为以大于20Hz的带宽测量离开燃料系统的燃料的质量流率。控制器被配置为基于由流量测量系统测量的燃料的质量流率来动态地调整燃料测量系统的冲程以改变燃料的流率。
