Estimating the term…
In a fuel supply system for an internal combustion engine having two separate storage containers for liquid fuels, both connected to a first controllable valve which is connected, via a connecting line including a fuel pump to an inlet of a second controllable valve having two outlets in communication by separate fuel lines with a fuel injection nozzle of the internal combustion engine, each of the two separate fuel lines includes a fuel pressure regulator, one being in communication with one and the other with the other of the two separate fuel storage containers for returning exess fuel to the fuel storage container from which fuel is being supplied to the fuel injection nozzle.
A fuel supply system for an internal combustion engine having two separate storage containers (1, 13) for liquid fuel, a first controllable valve (5) having two inlets, connected via fuel lines each to one of the storage containers (11, 13) and an outlet, which is connected by a fuel pump (2) to the inlet of a second controllable valve (6), the second controllable valve (6) having two outlets extending to a fuel injection nozzle of the internal combustion engine via two separate fuel lines (9, 15), each of two separate fuel lines containing a fuel pressure regulator (11, 17) between the second valve (6) and the fuel injection nozzle (12) and each fuel regulator being in communication with one of the fuel storage containers by a return line (14, 18) extending to the respective storage containers (1, 13) from the respective fuel pressure regulator (11, 17).
