Abstract: A fuel supply system and method of controlling fuel flow through a supply system is provided including a variable flow, i.e. speed, electric fuel transfer pump and a control system adapted to variably control the transfer pump based on fuel demand of the engine. The system provides improved transient response by providing the transfer pump with a feed forward speed/flow command based on engine fueling demand determined based on engine operating conditions. The transfer pump is controlled based on fuel demand not necessarily achieved yet by the high pressure pump and injectors. Therefore, this system controls the EFTP substantially simultaneously with controlling the high pressure pump and injectors to optimize fuel flow through the entire system ensuring the minimum required fuel flow is passing through the second the fuel filtration system, hence maximizing steady state fuel filtration efficiency, and minimizing surge effects on filtration efficiency.

Abstract translation: 提供了一种控制通过供应系统的燃料流量的燃料供应系统和方法，其包括可变流量，即速度电动燃料输送泵和适于基于发动机的燃料需求可变地控制输送泵的控制系统。 该系统通过为转印泵提供基于基于发动机操作条件确定的发动机加油需求的前馈速度/流量命令来提供改进的瞬态响应。 基于高压泵和喷射器不一定实现的燃料需求来控制输送泵。 因此，该系统通过控制高压泵和喷射器来控制EFTP，以优化通过整个系统的燃料流量，确保最小的所需燃料流量通过第二个燃料过滤系统，从而最大化稳态燃油过滤效率， 减少对过滤效率的浪涌影响。
