Description

Technical Field

[0001] The utility model relates to the technical field of using 0# diesel in a diesel vehicle under low temperature conditions, in particular to a device for using 0# diesel under low temperature conditions. Background Art

[0002] With the rapid development of my country's economy, the application scope of diesel trucks is becoming wider and wider. At present, light diesel is used for automotive diesel. The basis for selecting diesel is the ambient temperature during use. When the ambient temperature is above 4°C, 0# diesel is selected, when the ambient temperature is between -5°C and -14°C, -20# diesel is selected, and when the ambient temperature is between -14°C and -29°C, -35# diesel is selected. Because in winter, if 0# diesel is used in diesel vehicles, especially in diesel vehicles in the Northeast, 0# diesel will solidify quickly, and diesel wax will appear in the fuel tank and pipelines. Therefore, low-grade diesel must be used. However, the price of low-grade diesel is much higher than that of 0# diesel, and the supply of low-grade diesel is also much lower than that of 0# diesel. Under low temperature conditions, it is difficult to refuel diesel trucks, and the cost is increased, which is not conducive to the economic value of diesel trucks and restricts the long-term development of diesel vehicles. Summary of the invention

[0003] In order to solve the technical problem that diesel trucks cannot use 0# diesel under low temperature conditions, the utility model provides a device for using 0# diesel under low temperature conditions. The diesel truck is provided with a main fuel tank loaded with 0# diesel and an auxiliary fuel tank loaded with -35# diesel. Under low temperature conditions, -35# diesel is used to supply fuel to the diesel engine at the beginning of the diesel truck starting and when the truck is parked and idling. After starting, the fuel supply pipeline is replaced through PLC interlocking control, and heated 0# diesel is used to supply fuel to the diesel engine. The 0# diesel is heated autonomously to avoid the wax solidification of 0# diesel under low temperature conditions. -35# diesel and 0# diesel are automatically switched and accurately controlled, which minimizes the dependence on -35# diesel, reduces the operating cost of the diesel truck, ensures the fuel supply efficiency of the diesel truck, and improves the economic value of the diesel truck.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A device for using 0# diesel under low temperature conditions, comprising a main fuel tank, a subsidiary fuel tank being arranged outside the main fuel tank, the main fuel tank and the subsidiary fuel tank being connected to an oil inlet control valve with interlocking control through a 1# oil outlet pipe and a 2# oil outlet pipe, the oil inlet control valve being connected to a diesel engine through an oil inlet pipe, the diesel engine being connected to an oil return control valve with interlocking control through an oil outlet pipe, the oil return control valve being connected to the main fuel tank and the subsidiary fuel tank through a 1# oil return pipe and a 2# oil return pipe, one side of the diesel engine being connected to an air intake pipe, the main fuel tank, the 1# oil outlet pipe, the 1# oil return pipe and the air intake pipe being all provided with electric heating wires, the electric heating wires being connected to a vehicle-mounted generator through a power line; a temperature sensor being arranged at the lower part of the main fuel tank, the temperature sensor being connected to a PLC interlocking controller, the PLC interlocking controller interlockingly controlling the oil inlet control valve and the oil return control valve.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1.

The power supply is stable, and the electric heating wire heats 0# diesel with high heating efficiency and stable heating effect, thus relieving the waxing state of 0# diesel under low temperature conditions and avoiding the wax solidification phenomenon when using 0# diesel under low temperature conditions.

[0012] 2. The PLC interlocking controller interlocks and controls the oil inlet control valve and the oil return control valve, accurately controls the oil circuit switching between the -35# diesel oil circuit and the 0# diesel oil circuit, reduces the consumption of -35# diesel to a minimum, accurately controls the diesel usage, reduces the operating cost of diesel vehicles, ensures the fuel supply efficiency of diesel vehicles, and improves the economic value of diesel vehicles.

[0013] 3.

[0020] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figure 1-Figure 2 As shown, the working principle of a device for using 0# diesel in low temperature conditions is as follows: an auxiliary fuel tank 2 loaded with -35# diesel is added next to the main fuel tank 1 loaded with 0# diesel, and -35# diesel is used for fuel supply when the diesel vehicle is started and when it is parked and idling. An electric heating wire 18 is arranged in the main fuel tank 1 loaded with 0# diesel, 1# oil outlet pipe 3, 1# oil return pipe 5 and 1# filter 21, and the electric heating wire 18 is connected to the on-board generator 20 of the diesel vehicle. During the starting process of the diesel vehicle, the on-board generator 20 starts to generate electricity. After the electric heating wire 18 is energized, it heats the 0# diesel in the main fuel tank 1, 1# oil outlet pipe 3, 1# oil return pipe 5 and 1# filter 21. The 0# diesel in pipe 3, 1# oil return pipe 5 and 1# filter 21 is heated to eliminate the wax state of diesel, and the temperature sensor 15 in the main fuel tank 1 transmits the temperature value to the PLC interlock controller 16. When the 0# diesel operating temperature of 4°C is reached, the PLC interlock controller 16 interlocks and controls 17 the oil inlet control valve 7 and the oil return control valve 8 to switch the oil circuit from -35# diesel to 0# diesel. During normal driving of the diesel vehicle, the heated 0# diesel is used to supply the diesel engine 13, avoiding the wax solidification of 0# diesel under low temperature conditions, reducing the dependence on -35# diesel, reducing the operating cost of diesel vehicles, ensuring the refueling efficiency of diesel vehicles, and improving the economic value of diesel vehicles.

[0022] like Figure 1-Figure 2As shown, a device for using 0# diesel in low temperature conditions comprises a main oil tank 1, an auxiliary oil tank 2 is arranged outside the main oil tank 1, the main oil tank 1 and the auxiliary oil tank 2 are connected to an oil inlet control valve 7 with an interlocking control 17 through a 1# oil outlet pipe 3 and a 2# oil outlet pipe 4, the oil inlet control valve 7 is connected to a diesel engine 13 through an oil inlet pipe 9, the diesel engine 13 is connected to an oil return control valve 8 with an interlocking control 17 through an oil outlet pipe 10, and the oil return control valve 8 is connected to the main oil tank 1 and the auxiliary oil tank 2 through a 1# oil return pipe 5 and 2# oil return pipe 6 is connected, main tank 1-1# oil outlet pipe 3-oil inlet control valve 7-oil inlet pipe 9-diesel engine 13-oil outlet pipe 10-oil return control valve 8-1# oil return pipe 5-main tank 1 is the oil supply line of 0# diesel, auxiliary tank 2-2# oil outlet pipe 4-oil inlet control valve 7-oil inlet pipe 9-diesel engine 13-oil outlet pipe 10-oil return control valve 8-2# oil return pipe 6-auxiliary tank 2 is the oil supply line of -35# diesel; under low temperature conditions, the diesel vehicle starts or the diesel vehicle idling stops In the process, the fuel supply pipeline of -35# diesel is used to provide kinetic energy to the diesel vehicle. When the diesel vehicle is started and in normal driving, the fuel supply pipeline of 0# diesel is used to provide kinetic energy to the diesel vehicle. One side of the diesel engine 13 is connected to the intake pipe 14. The main fuel tank 1, 1# oil outlet pipe 3, 1# oil return pipe 5 and intake pipe 14 are all provided with electric heating wire 18. The electric heating wire 18 is connected to the vehicle-mounted generator 20 through a power line 19. After the diesel vehicle is started, the vehicle-mounted generator 20 autonomously supplies power to the electric heating wire 18. The electric heating wire 18 heats the 0# diesel in the main fuel tank 1, 1# oil outlet pipe 3 and 1# oil return pipe 5 and heats the air in the intake pipe 14. The purpose of heating the intake pipe 14 is to increase the temperature of the air entering the diesel engine 13, increase the reaction effect between air and diesel, reduce the start time of the diesel vehicle, and reduce the use of -35# diesel. The main fuel tank 1, 1# oil outlet pipe 3 and 1# oil return pipe 5 are heated to remove the waxing state of 0# diesel and avoid the wax solidification of 0# diesel under low temperature conditions.A temperature sensor 15 is arranged at the lower part of the main oil tank 1, and the temperature sensor 15 is connected to a PLC interlocking controller 16. The PLC interlocking controller 16 interlocks and controls the oil inlet control valve 7 and the oil return control valve 8. When the diesel vehicle is started at the beginning under low temperature conditions, the 0# diesel in the main oil tank 1 is in a waxy state. The temperature transmitted by the temperature sensor 15 in the main oil tank 1 to the PLC interlocking controller 16 is lower than 4°C. The PLC interlocking controller 16 controls the oil inlet control valve 7 and the oil return control valve 8 to switch to the oil supply pipeline of -35# diesel, which is a diesel engine. The engine 13 provides -35# diesel. When the diesel vehicle is started, the diesel generator 20 rotates to provide electricity, which is used to supply power to the electric heating wire 18. The electric heating wire 18 heats the 0# diesel, and the temperature of the 0# diesel rises. When the temperature transmitted by the temperature sensor 15 is higher than 4°C, the PLC interlocking controller 16 controls the oil inlet control valve 7 and the oil return control valve 8 to switch to the oil supply pipeline of the 0# diesel, and provide the diesel engine 13 with 0# diesel. The diesel vehicle runs normally, and the -35# diesel supply pipeline and the 0# diesel supply pipeline realize seamless automatic switching. ;

[0023] Furthermore, a 1# filter 11 is provided on the 1# oil outlet pipe 3, a 2# filter 12 is provided on the 2# oil outlet pipe 4, an electric heating wire 18 is provided in the 1# filter 11, and the electric heating wire 18 is connected to the vehicle-mounted generator 20. 0# diesel flows through the 1# filter 11, and the electric heating wire 18 needs to be provided in the 1# filter 11 to heat the 0# diesel.

[0024] Furthermore, the main fuel tank is loaded with 0# diesel, and the auxiliary fuel tank is loaded with -35# diesel.

[0025] Furthermore, the oil inlet control valve 7 and the oil return control valve 8 are both manual / electric double-control two-position three-way reversing valves. The oil inlet control valve 7 and the oil return control valve 8 are electrically controlled and connected to the PLC interlock controller 16. The seamless automatic switching of the -35# diesel fuel supply pipeline and the 0# diesel fuel supply pipeline is interlocked and controlled by the PLC interlock controller 16 according to the temperature of the 0# diesel in the main fuel tank 1. The manual control of the oil inlet control valve 7 and the oil return control valve 8 is to prevent manual replacement of the fuel supply pipeline in emergency situations and in the parking idling state. Before the vehicle stops, the fuel supply pipeline is manually switched during idling operation, from the 0# diesel fuel supply pipeline to the -35# diesel fuel supply pipeline. After running for 3-5 minutes, the diesel vehicle is turned off. In this way, the pipeline is filled with -35# diesel after the vehicle stops, ensuring that the pipeline is not waxed under low temperature conditions, preparing for the next start of the vehicle.

[0026] Furthermore, the PLC interlocking controller 16 is provided with a temperature display 21 .
