Abstract
A fuel control arrangement includes an injector control valve, a fuel supply structure including a primary supply path, a secondary supply path, and a splitter valve configured to split fuel flow between the primary supply path and the secondary supply path to thereby regulate fuel supply. The fuel control arrangement also includes a fuel injector directly connected to the injector control valve. The splitter valve is configured to split fuel flow between the secondary path and the injector control valve in response to a fuel pressure indicative of fuel demand. Further, the splitter is provided distal to the fuel injector and the injector control valve, to operate under different environmental conditions from the injector and the injector control valve. The injector control valve is actuated by a fluid pressure system controlled by a solenoid.
