FUEL FEED MODULE SYSTEM OF THE SADDLE TYPE FUEL TANK

摘要

PURPOSE: A fuel feed module system of a saddle type fuel tank is provided to secure the temperature control of fuel and to solve the temperature imbalance between the fuel of a main tank area and the fuel of an auxiliary tank area by operating three jet pumps with the engine return fuel of high temperature. CONSTITUTION: A fuel feed module system of a saddle type fuel tank is composed of a return line(12), a jet pump module, an auxiliary jet feed line(230), an auxiliary jet pump, and a feeding line(220). The return line returns the fuel of the high temperature returning from an engine(10) to a fuel tank(20). The jet pump module comprises a feed jet pump(152). The feed jet pump uses the fuel of high temperature returning from an engine according to a return line as an operating fluid. The auxiliary jet feed line supplies the fuel branched in the jet pup module to the auxiliary jet pump of an auxiliary tank area(22). The auxiliary jet pump is connected to the auxiliary jet feed line. The auxiliary jet pump moves the fuel of the auxiliary tank area to the main tank area by using the returned fuel as an operating fluid. The feeding line supplies the fuel of the auxiliary tank area to the fuel feed module of the main tank area.
