Abstract
A dual fuel system for an internal combustion engine includes a plurality of fuel injectors, a first fuel pump and a first fuel conduit extending to the plurality of fuel injectors, and a second fuel pump and a second fuel conduit extending to a fuel manifold fluidly connected to the plurality of fuel injectors. The dual fuel system also includes an overflow buffer arranged to receive a volume of the second fuel expelled from the second fuel conduit, and a valve movable from a closed position to an open position fluidly connecting the overflow buffer to the second fuel conduit. Expelling fuel from the second fuel conduit enables a rapid pressure drop in a supply pressure of the second fuel to hasten switchover of the internal combustion engine between fuel type.
