ABSTRACT:
A fuel system is provided with an accelerator pump. The accelerator pump has a single influent port and multiple effluent ports. The single influent port draws fuel from a single charge former into a fuel chamber of the accelerator pump. An operational linkage controls a release of the fuel such that the fuel in the fuel chamber is released into the charge formers during periods of rapid acceleration and like operating conditions. Upon actuation, the accelerator pump discharges an additional amount of fuel into multiple charge formers through the corresponding effluent ports of the accelerator pump. Accordingly, a single accelerator pump can be used with multiple charge formers to reduce to overall size of an assembled engine.
