Abstract

A fuel system for an engine is disclosed. The fuel system has a first source configured to pressurized fuel to a first pressure, and a second source configured to pressurized fuel to a second pressure. The fuel system also has a fuel injector (32) configured to receive and inject fuel into the engine, and a single valve (102) disposed between the fuel injector and the first and second sources. The single valve is in fluid communication with the first and second sources and the fuel injector, and able to deliver variable pressure fuel to the fuel injector.
