Abstract

PURPOSE: A fuel tank for a diesel engine of a vehicle is provided to start an engine smoothly and to inhibit the engine from being stopped during driving a vehicle by preventing paraffin in diesel oil from being accumulated on a fuel filter through a pipe even though the paraffin is deposited at the bottom of a fuel tank. CONSTITUTION: A fuel tank(30) is formed by an upper and a lower plate(10,20), and a pipe(40) connected to a fuel feed pie(50) is set on a side in the fuel tank. A return pipe(60) is installed on a side of the fuel tank having the pipe. Herein, the pipe is used with a venturi tube available for vertical expanding and contracting. A feed hole(81) is formed at the lower end of the venturi tube type pipe. The feed hole supplies the diesel oil into the pipe as well as expands and contracts the pipe vertically by moving up and down depending on the amount of diesel oil(90) in the fuel tank. The feed hole is connected with a float(80). The float is floated by buoyancy of the diesel oil in the fuel tank. The venturi tube type pipe is expanded and contracted when the float is moved up and down depending on the amount of diesel oil in the fuel tank. After the diesel flows into a fuel filter(70) through the fuel feed pipe from the venturi tube type pipe, paraffin contained in the diesel oil may be deposited at the bottom of the fuel tank. Even though the paraffin is deposited, the paraffin is not supplied to the fuel filter through the pipe. Therefore, an engine is not stopped easily.

In the inner), a hollow cylindrical pipe 40 'coupled to the fuel supply pipe 50' is intermittently installed at one end thereof, and one side of the storage part 30 'in which the pipe 40' is intermittently installed. The return pipe 60 'is interpolated.

이러한 종래 디젤 자동차용 연료탱크는 상판(10')과 하판(20')이 결합되는 것에 의해 형성된 보관부(30')에 소정의 디젤(90')이 보관되고 있다.In the conventional fuel tank for diesel vehicles, a predetermined diesel 90 'is stored in a storage part 30' formed by combining the upper plate 10 'and the lower plate 20'.

또한, 상기 보관부(30')에 보관중인 디젤(90')은 자동차를 운행시, 상기 보관부(30')에 내삽지게 설치된 파이프(40')를 통하여 연료공급파이프(50')를 통해 연료필터(70')로 공급되고, 상기 연료필터(70')로 공급된 디젤(90')은 먼지등과 같은 오물이 제거된 상태로 연료분사펌프(미도시')를 통해 엔진(미도시')에 공급되고 있다.In addition, the diesel 90 'stored in the storage unit 30' is driven through a fuel supply pipe 50 'through a pipe 40' installed in the storage unit 30 'to be inserted into the storage unit 30'.
