  • System and method for controlling a low pressure pump to prevent vaporization of fuel at an inlet of a high pressure pump
    Patent number: 9567915
    Abstract: A system according to the principles of the present disclosure includes a pump control module and a fuel vaporization module. The pump control module controls a first pump to deliver fuel from a fuel tank to a second pump through a fuel line. The pump control module controls the second pump to pressurize fuel from the fuel line and to deliver the pressurized fuel to a fuel rail. The fuel vaporization module determines whether fuel at an inlet of the second pump is vaporizing based on an engine operating condition. The pump control module increases an output of the first pump when fuel at the inlet of the second pump is vaporizing.
