초록 ▼

A fuel delivery system for internal combustion engines in which an electric-motor fuel pump supplies fuel under pressure from a tank to a fuel injector carried by the engine, and excess fuel is returned by a pressure regulator from the engine to the supply tank. A restriction is positioned in the fuel return line to restrict flow of return fuel therethrough, and thereby create a back-pressure of fuel in the return line. A pressure sensor is coupled to the return line between the pressure regulator and the restriction and drives the fuel pump as an inverse function of fuel pressure in the return line, and thus as a direct function of fuel demand at the engine.

대표청구항 ▼

A fuel delivery system for an internal combustion engine that includes a fuel supply with a pump responsive to application of electrical power for delivering fuel under pressure, an engine air intake manifold, fuel delivery means coupled to said fuel supply for controlled delivery of fuel from said supply to said manifold, pressure regulator means having a first input responsive to fuel pressure at said fuel delivery means, a reference input connected to said air intake manifold and an outlet connected through a fuel return to said supply, said regulator means being responsive to a predetermined pressure differentials across said fuel delivery means for passing excess fuel through said return to said supply, and means for applying electrical power to said pump; characterized in that said power-applying means comprises: means in said return between said regulating means and said supply for restricting flow of fuel therethrough and thereby developing a back pressure of fuel in said return between said restricting means and said regulator means, a differential pressure sensor having a first input coupled to said return between said restricting means and said regulator means, a second input connected to receive air at ambient pressure and an output for supplying an electrical sensor signal as a direct continuous function of a differential between said back pressure and ambient caused by fuel flow through said return, and means for applying electrical power to said pump as a continuous inverse function of said sensor signal.
