Problems solved by technology

The traditional fuel tank has a high height, which is only suitable for diesel locomotives with a high floor. If the fuel tank is directly installed on a diesel locomotive with a low floor, the fuel tank and the fuel pipeline connected to it will be more likely to collide with obstacles near the track causing fuel leaks

Embodiment 2

[0068] This embodiment provides another fuel system on the basis of the above embodiments.

[0069] Figure 6 It is a schematic structural diagram of the fuel system provided in Embodiment 2 of the present application. Such as Figure 6 As shown, the fuel system provided in this embodiment includes: a first fuel tank 10 , a second fuel tank 40 , a first fuel pump 31 , a second fuel pump 32 , a third fuel pump 33 and an internal combustion engine 20 . Wherein, the first fuel tank 10 adopts the realization method provided by any solution of the above-mentioned embodiments, and the first fuel tank 10 is arranged at the bottom of the rail vehicle. The second oil tank 40 can adopt the oil tank commonly used in the prior art, and is arranged on the top of the rail vehicle.

[0070] The first oil pump 31 is used to pump the fuel in the first chamber 14 of the first fuel tank 10 into the second chamber 15 . The second fuel pump 32 is used to pump the fuel in the second chamber 15 ...

Embodiment 3

[0075] This embodiment provides a rail vehicle, including: the fuel system provided by any one of the above embodiments.

[0076] In the technical solution provided by this embodiment, the first fuel tank can be arranged at the bottom of the rail vehicle, the first fuel tank includes a cavity for containing fuel and a first partition vertically arranged in the cavity, the first partition The plate divides the containing cavity into a first chamber with a larger volume and a second chamber with a smaller volume, and the first oil pump is used to pump the fuel in the first chamber to the second chamber, so that the fuel in the second chamber The height of the fuel oil level is relatively high, and it is not easy to cause air suction; and the first fuel tank provided by this embodiment can be set according to the height of the rail vehicle floor, if it is set to a flat shape, it can adapt to vehicles with low floors, and avoid excessive fuel tank position. The problem arises of b...

Abstract

The embodiment of the invention provides a fuel system and a rail vehicle. The fuel system comprises a first fuel tank and a first fuel pump, wherein the first fuel tank is arranged at the bottom of the rail vehicle and comprises a tank body with a containing cavity and a first partition plate vertically arranged in the containing cavity, the containing cavity is divided into a first chamber and asecond chamber by the first partition plate, and the volume of the second chamber is smaller than that of the first chamber; and the first fuel pump is used for pumping fuel in the first chamber to the second chamber. According to the fuel system and the rail vehicle, the fuel tank or a fuel pipeline can be prevented from colliding with ground obstacles.

Description

technical field [0001] The application relates to rail vehicle power supply technology, in particular to a fuel system and a rail vehicle. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. Rail vehicles are mainly divided into two types: diesel locomotives and electric locomotives. Among them, diesel locomotives convert the heat energy generated by fuel combustion into mechanical energy that drives the wheels. [0003] Usually, a fuel tank is arranged at the bottom of the diesel locomotive, and an oil pump is used to pump the fuel in the fuel tank to the internal combustion engine. The traditional fuel tank has a high height, which is only suitable for diesel locomotives with a high floor. If the fuel tank is directly installed on a diesel locomotive with a low floor, the fuel tank and the f...
