OSTI ID:5551850

This patent describes an internal combustion engine powered by a fuel of liquefied petroleum gas. It comprises at least one cylinder head which includes an intake port region communicating with a combustion chamber through an intake valve; a fuel injection rail including at least one fuel injector, all injectors operably connected to all intake port regions with one intake region connected to one injector whereby fuel may be injected into the intake regions; a conduit connecting the container to the injection rail; means for pumping the fuel from the injection rail and maintaining the fuel at a temperature below a temperature value and pressure above a pressure value required to sustain the fuel in a liquid state whereby the fuel in the liquid state is transferred from the storage container to the rail.
