Abstract
A non-return fuel distribution system or deadheaded fuel distribution system for an internal combustion engine having one or more fuel injectors mounted on a fuel rail on the engine, has a fuel pressure transducer mounted on the fuel rail to sense the fuel pressure in the rail and generate an electrical signal representing such pressure. The electrical signal is combined in a controller to operate an electrically operated variable pressure fuel pump to generate and maintain the fuel pressure necessary to operate the electrically operated fuel injectors in their linear operating pulse range.
