| 摘要 | A fuel system for a dual fuel power source includes a first fuel circuit fluidly connected to the power source, a second fuel circuit separate from the first fuel circuit and fluidly connected to the power source, and a pressure regulator fluidly connected to the first fuel circuit. The pressure regulator is configured to vent a first fuel from the first fuel circuit to an aftertreatment system fluidly connected to the power source in response to a pressure difference between the first and second fuel circuits being less than or equal to a pressure difference threshold. | ||
