FUEL SUPPLY SYSTEM

摘要

PURPOSE: A fuel delivery system is provided to reduce troubles of an internal combustion engine caused by foreign materials by supplying clean fuel to the internal combustion engine. CONSTITUTION: A fuel delivery system comprises a fuel pump module(10), a fuel supply line(40), a fuel recovery line(50), and a bypass tube(20). The fuel pump module is installed inside a fuel tank(100) and comprises a reservoir(15) filled with a certain amount of fuel and a fuel pump(11) which sucks the fuel from the reservoir and feeds the fuel to an internal combustion engine(60). The fuel supply line supplies the fuel from the fuel pump module to the internal combustion engine. The fuel recovery line returns the fuel from the internal combustion engine to the fuel tank. The bypass tube is formed inside the reservoir to connect the fuel recovery line and the fuel pump and directly supply the fuel returned through the fuel recovery line to the fuel pump via the bypass tube.
