Abstract
A fuel vapor handling system for a dual fluid fuel injection system, including: a fuel supply apparatus and a gas supply apparatus for respectively supplying liquid fuel and gas-vapor mixture to at least one delivery injector of the dual fluid fuel injection system, the fuel supply apparatus including a fuel pump; and a fuel vapor control device providing a fluid communication between the fuel supply apparatus downstream of the fuel pump and the gas supply apparatus to allow fuel vapor present within the fuel supply apparatus to pass to the gas supply apparatus for subsequent delivery by the at least one delivery injector. The fuel vapor device preferably allows the pressure of the liquid fuel supplied to the at least one delivery injector to be substantially equalized with the pressure of the gas supplied to the delivery injector.
