Abstract:
1. A fuel injection priming system for an engine, comprising: a fuel tank; a fuel pump in fluid communication with the fuel tank; a fuel supply rail; a first fuel line connected to the fuel pump and the fuel supply rail; a plurality of fuel injectors connected to the fuel supply rail; a second fuel line extending between the fuel pump and the plurality of fuel injectors, the second fuel line connected to the plurality of fuel injectors and in fluid communication with a pressurized fuel supply via a diverter device in fluid communication with the fuel pump and the second fuel line which allows fuel from the fuel pump to pressurize the fuel injectors via the second fuel line during a priming operation, the fuel rail and the second fuel line forming parallel flow paths between the fuel pump and the plurality of fuel injectors; and a one-way valve in fluid communication with the diverter device to manage the pressurized fuel provided to the plurality of fuel injectors during the priming operation and to allow fuel to pass to the fuel tank during normal operation; wherein the fuel pump forms an injector supply pump providing pressurized fuel to the fuel injectors at an injector supply pressure.
