Embodiment Construction

[0018] combine figure 1 , figure 2 and image 3 , a dual-cavity fuel tank fuel supply system for a heavy truck vehicle, comprising a fuel engine 1, a horizontal fuel tank and a manual switching valve 2. A filler port 10 is provided on the tank wall of the horizontal fuel tank, and a closed partition 9 is arranged in the horizontal fuel tank, and the closed partition is facing the filler port. A blockboard 11 is arranged in the filler port, and the blockage plate separates the filler port into No. 1 refueling port and No. 2 refueling port. The airtight partition divides the inner chamber of the horizontal fuel tank into a No. 1 fuel chamber 3 and a No. 2 fuel chamber 4. The No. 1 refueling port is connected to the No. 1 fuel chamber, and the No. 2 refueling port is connected to the No. 2 fuel chamber. No. 1 oil outlet 5 and No. 1 oil return port 6 are arranged on the tank wall corresponding to No. 1 fuel chamber, and No. 2 oil outlet 7 and No. 2 oil return port 8 are arrang...

Abstract

The invention discloses an oil supply system of a dual-cavity fuel tank in a heavy truck. The oil supply system is characterized by comprising a fuel machine, a horizontal fuel tank and a manual changeover valve, wherein a sealed baffle is arranged in the horizontal fuel tank, used for dividing an inner cavity in the horizontal fuel tank into a first fuel cavity and a second fuel cavity, and arranged over against an oil charge hole; a blocking plate is arranged in the oil charge hole and is used for dividing the oil charge hole into a first oil charge hole and a second oil charge hole; the first oil charge hole is communicated with the first fuel cavity; the second oil charge hole is communicated with the second fuel cavity; the manual changeover valve is connected with the fuel machine through a main oil supply pipeline and a main oil return pipeline; and the first fuel cavity and the second fuel cavity are respectively connected with the manual changeover valve through the oil supply pipelines and the oil return pipelines of the first fuel cavity and the second fuel cavity. According to the oil supply system, the flexible changeover of 'dual fuel in one truck' is realized through the manual changeover valve, so that the phenomenon of the increment of the fuel cost as the heavy truck cannot change the fuel in time is avoided and the transportation cost can be effectively reduced.

Description

technical field [0001] The invention relates to a double-cavity fuel tank oil supply system suitable for heavy truck vehicles. Background technique [0002] In general-purpose heavy-duty trucks, the fuel supply system is basically supplied by a set of fuel tanks to the vehicle. Especially in winter, when the temperature is relatively low, it is not easy for one type of diesel to meet the transportation needs. At present, the common method is to use a heating device or directly replace other types of diesel. Both of these solutions will cause transportation problems. Increased cost and inconvenience. Therefore, it is necessary to provide a dual-cavity fuel tank oil supply system suitable for heavy trucks, so as to well solve the above problems. Contents of the invention [0003] The task of the present invention is to solve the technical defects existing in the fuel tank fuel supply system of heavy truck vehicles in the prior art, and provide a double-cavity fuel tank fue...
