Problems solved by technology

[0002] In general-purpose heavy-duty trucks, the fuel supply system basically uses a set of fuel tanks to supply fuel to the vehicle; there is a big problem: in winter, when a single fuel tank is used in different regions (such as Guangzhou to Inner Mongolia) ), the type of fuel cannot be switched in time (0# to -20#), which will lead to an increase in transportation costs

Embodiment Construction

[0011] Referring to the accompanying drawings, a dual fuel tank fuel supply system for heavy trucks includes a fuel engine 1 and a fuel tank. The above-mentioned fuel tanks include a No. 1 fuel tank 2 and a No. 2 fuel tank 3, and the No. 1 fuel tank 2 and the No. 2 fuel tank 3 can alternatively be connected to a fuel engine.

[0012] More specifically, the fuel delivery pipeline 6 of the No. 1 fuel tank 2 and the fuel delivery pipeline 7 of the No. 2 fuel tank 3 are connected to the main fuel delivery pipeline 8 communicating with the fuel engine 1 through the first synchronization valve 4 . The oil return line 9 of the No. 1 fuel tank 2 and the oil return line 10 of the No. 2 fuel tank 3 are connected to the main oil return line 11 communicated with the fuel engine through the second synchronous valve 5 .

[0013] In the above method, when the selection control first and second synchronous valves are both in the C state, the fuel in the No. 1 fuel tank enters the fuel engine ...

Abstract

The invention discloses a fuel supply system of double fuel tanks of a heavy truck. The fuel supply system is characterized by comprising a No.1 fuel tank and a No.2 fuel tank, wherein the No.1 fuel tank and the No.2 fuel tank can select one ground connection combustion engine; the fuel pipeline of the No.1 fuel tank and the oil pipeline of the No.2 fuel tank are connected into a main fuel pipeline communicated with the combustion engine by virtue of a first synchronous valve; and the fuel return line of the No.1 fuel tank and the fuel return line of the No.2 fuel tank are connected into the main fuel return line communicated with the combustion engine by virtue of a second synchronous valve. In the fuel supply system, two fuel tanks are adopted, thus different types of fuels can be respectively added, the fuel supply system not only can supply fuels like a single fuel supply system but also can adapt to changeful weather and climate. The fuel supply system can be switched to the other fuel tank storing other types of fuels for supplying fuels to switch 'one truck with double fuels', thus the phenomenon of fuel cost increase brought by delay fuel replacement is overcome, and the transportation cost can be effectively lowered.

Description

technical field [0001] The invention relates to a fuel tank of a heavy truck vehicle and its fuel supply system. Background technique [0002] In general-purpose heavy-duty trucks, the fuel supply system basically uses a set of fuel tanks to supply fuel to the vehicle; there is a big problem: in winter, when a single fuel tank is used in different regions (such as Guangzhou to Inner Mongolia) ), the type of fuel cannot be switched in time (0# to -20#), which will lead to an increase in transportation costs. Therefore, it is imperative to provide a double fuel tank oil supply system suitable for heavy truck vehicles. Contents of the invention [0003] The task of the present invention is to provide a dual fuel tank oil supply system for heavy truck vehicles. [0004] Its technical solutions are: [0005] A fuel supply system with dual fuel tanks for heavy trucks, including a fuel engine and a fuel tank. The fuel tanks include a No. 1 fuel tank and a No. 2 fuel tank. The ...
