The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1 and Figure 2 A fuel supply system 100 for a vehicle according to an embodiment of the present invention is described.

[0028] like Figure 1 and Figure 2 As shown, the oil supply system 100 according to the embodiment of the present invention includes: an oil pump 10 , an oil storage container 20 and a pressure stabilizing component 30 .

[0029] The oil pump 10 is connected to the oil storage container 20; the pressure stabilizing assembly 30 includes: a pressure stabilizing container 31 and a pressure regulator 32, the pressure stabilizing container 31 defines a pressure stabilizing chamber 311, the oil pump 10 is connected to the pressure stabilizing chamber 311 to guide the fuel in the oil storage container 20 into the pressure stabilizing chamber 311, at least part of the structure of the pressure regulator 32 is arranged in the pressure stabilizing chamber 311, and part of the structure of the pressure regulator 32 can move relative to the pressure stabilizing container 31 to change the volume of the pressure stabilizing chamber 311.

[0030] Among them, the oil pump 10 is connected to the oil storage container 20. As some embodiments of the present application, the oil pump 10 is connected to the oil storage container 20 through a pipeline. The oil pump 10 can pump out the fuel in the oil storage container 20 and can increase the pressure of the fuel. As some embodiments of the present application, the oil pump 10 is a plunger oil pump, and a control valve is provided between the oil pump 10 and the oil storage container 20, and the control valve is connected to a controller, and the controller can control the control valve to open or close the control valve, and the oil pump 10 can drive the cam to rotate to drive the plunger of the oil pump 10 to move, compress the fuel in the plunger cavity, so as to increase the fuel pressure.

[0031] As some embodiments of the present application, the control valve may be configured as a solenoid valve.

[0032] The pressure stabilizing assembly 30 includes a pressure stabilizing container 31 and a pressure regulator 32. The pressure stabilizing container 31 can define a pressure stabilizing chamber 311. The oil pump 10 is connected to the pressure stabilizing chamber 311 to introduce the fuel in the oil storage container 20 into the pressure stabilizing chamber 311. At least part of the structure of the pressure regulator 32 is arranged in the pressure stabilizing chamber 311, that is, part of the structure of the pressure regulator 32 is arranged in the pressure stabilizing chamber 311, or the entire structure of the pressure regulator 32 is arranged in the pressure stabilizing chamber 311, and part of the structure of the pressure regulator 32 can move relative to the pressure stabilizing container 31 to change the volume of the pressure stabilizing chamber 311.

[0033] As some embodiments of the present application, the pressure stabilizing chamber 311 may be applied to, but is not limited to, a V-type engine.

[0034] As some embodiments of the present application, when the vehicle's fuel supply system 100 is working, the oil pump 10 can pump out the fuel in the oil storage container 20 and increase the pressure of the pumped fuel, and send the pumped fuel to the pressure stabilizing chamber 311 through the pipeline. The fuel in the pressure stabilizing chamber 311 can pass into the oil rail assembly 60 to spray fuel into the intake manifold or the cylinder. Since the pressure regulator 32 can change the volume of the pressure stabilizing chamber 311, the fuel pressure in the pressure stabilizing chamber 311 can be kept constant, and the frequency and amplitude of fuel pressure fluctuations can be reduced to stabilize the fuel pressure of the fuel supply system 100.

[0035] It should be noted that when the fuel pressure in the pressure stabilizing chamber 311 is relatively high, the pressure regulator 32 can increase the volume of the pressure stabilizing chamber 311 to reduce the fuel pressure in the pressure stabilizing chamber 311; when the fuel pressure in the pressure stabilizing chamber 311 is relatively low, the pressure regulator 32 can reduce the volume of the pressure stabilizing chamber 311 to increase the fuel pressure in the pressure stabilizing chamber 311.

[0036] Therefore, by defining the pressure stabilizing chamber 311 in the pressure stabilizing container 31 and enabling a partial structure of the pressure regulator 32 to move relative to the pressure stabilizing container 31 to change the volume of the pressure stabilizing chamber 311, the pressure of the oil in the pressure stabilizing chamber 311 can be adjusted to make the fuel pressure in the pressure stabilizing chamber 311 constant, thereby reducing the frequency and amplitude of fuel pressure fluctuations, thereby facilitating improving the power performance and combustion efficiency of the engine and reducing emissions.

[0037] In some embodiments of the present invention, Figure 2 As shown, the vehicle's fuel supply system 100 also includes: a controller, and the pressure stabilizing component 30 also includes: a pressure sensor 50, the pressure sensor 50 is used to detect the pressure value in the pressure stabilizing chamber 311, the controller is connected to the pressure sensor 50 and the pressure regulator 32, and the controller is constructed to control the movement of the pressure regulator 32 according to the information fed back by the pressure sensor 50.

[0038] Among them, the vehicle's fuel supply system 100 also includes a controller, which can be an engine controller or a vehicle controller. The voltage stabilizing component 30 also includes a pressure sensor 50, which is arranged in the pressure stabilizing chamber 311. The pressure sensor 50 is used to detect the pressure value in the pressure stabilizing chamber 311. The controller is connected to the pressure sensor 50, and the controller is connected to the pressure regulator 32. As some embodiments of the present application, the controller is connected to the pressure sensor 50 and the pressure regulator 32 by electrical connection.

[0039] The controller is constructed to control the movement of the pressure regulator 32 according to the information fed back by the pressure sensor 50. That is, the pressure sensor 50 can detect the pressure value in the pressure stabilizing chamber 311 and feed the pressure value back to the controller. The controller can control the pressure regulator 32 to change the volume of the pressure stabilizing chamber 311 according to the fed-back pressure value to adjust the pressure value of the pressure stabilizing chamber 311 so as to stabilize the fuel pressure of the fuel supply system 100.

[0040] As some embodiments of the present application, the feedback pressure value can be compared with the standard pressure value of the current operating condition of the engine. If the feedback pressure value is greater than the standard pressure value, the controller can control the pressure regulator 32 to increase the volume of the pressure stabilizing chamber 311 to reduce the fuel pressure in the pressure stabilizing chamber 311. If the feedback pressure value is less than the standard pressure value, the controller can control the pressure regulator 32 to reduce the volume of the pressure stabilizing chamber 311 to increase the fuel pressure in the pressure stabilizing chamber 311.

[0041] Such a setting enables the controller to control the action of the pressure regulator 32 according to the current pressure value in the pressure stabilizing chamber 311 , thereby being able to control the oil pressure of the fuel supply system 100 in real time, so as to keep the fuel pressure stable and improve the stability of the fuel supply system 100 .

[0042] As some embodiments of the present application, the standard pressure value may be a range value.

[0043] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the pressure stabilizing component 30 also includes: an oil drain valve, the oil storage container 20 is connected to the oil pump 10 through the first pipeline 1, the pressure stabilizing container 31 has an oil drain port 312, the oil drain port 312 is connected to the oil storage container 20 or the first pipeline 1 through the second pipeline 2, the oil drain valve is arranged in the second pipeline 2 and is connected to the controller, and the controller is constructed to control the oil drain valve according to the information fed back by the pressure sensor 50.

[0044] The pressure stabilizing component 30 further includes an oil drain valve, and the oil storage container 20 is connected to the oil pump 10 via the first pipeline 1. As some embodiments of the present application, the oil drain valve may be a solenoid valve. The pressure stabilizing container 31 has an oil drain port 312, and the oil drain port 312 is connected to the oil storage container 20 or the first pipeline 1 via the second pipeline 2, that is, the oil drain port 312 is connected to the oil storage container 20 via the second pipeline 2, or the oil drain port 312 is connected to the first pipeline 1 via the second pipeline 2, and the oil drain valve is disposed in the second pipeline 2 and is connected to the controller. As some embodiments of the present application, the controller is connected to the oil drain valve via an electrical connection.

[0045] The controller is configured to control the drain valve according to the information fed back by the pressure sensor 50, that is, the controller can control the drain valve to open or close according to the information fed back by the pressure sensor 50. As some embodiments of the present application, after the controller controls the pressure regulator 32 to operate to increase the volume of the pressure stabilizing chamber 311, if the fuel pressure value of the pressure stabilizing chamber 311 is still too large, the drain valve can be controlled to open to drain part of the fuel in the pressure stabilizing chamber 311. After the fuel in the pressure stabilizing chamber 311 is drained, it can flow back to the oil storage container 20 or the first pipeline 1 through the second pipeline 2, so that the pressure of the oil in the pressure stabilizing chamber 311 can be adjusted to make the fuel pressure in the pressure stabilizing chamber 311 constant, and reduce the frequency and amplitude of fuel pressure fluctuations.

[0046] As some embodiments of the present application, when it is necessary to reduce the fuel pressure value of the pressure stabilizing chamber 311 , the oil drain valve can be controlled to open to drain part of the fuel in the pressure stabilizing chamber 311 to reduce the fuel pressure value of the pressure stabilizing chamber 311 .

[0051] In some embodiments of the present invention, the side wall of the adjusting member 323 is dynamically sealed with the inner wall of the pressure-stabilizing chamber 311. It can be understood that the driving member 321 can drive the adjusting member 323 to move in the pressure-stabilizing chamber 311 to maintain the oil pressure stability of the oil supply system 100. By making the side wall of the adjusting member 323 dynamically seal with the inner wall of the pressure-stabilizing chamber 311, the volume of the pressure-stabilizing chamber 311 can be reliably and stably adjusted, which is beneficial to improving the reliability of the oil supply system 100.

When the adjusting member 323 is actuated, the first seal can move with the adjusting member 323, and the first seal can seal the gap between the adjusting member 323 and the inner wall of the pressure stabilizing chamber 311. Such a setting can more reliably and stably adjust the volume of the pressure stabilizing chamber 311, which is beneficial to further improve the reliability of the oil supply system 100.

The pressure-stabilizing container 31 has an avoidance hole, and the transmission rod 322 can be inserted into the avoidance hole and fixedly connected to the adjustment member 323.

[0056] By arranging the driving member 321 in the pressure-stabilizing container 31 and outside the pressure-stabilizing chamber 311, the driving member 321 does not occupy the volume of the pressure-stabilizing chamber 311, thereby increasing the amount of fuel that the pressure-stabilizing chamber 311 can accommodate, and can also reduce the rate at which the fuel erodes the driving member 321, which is beneficial to increasing the service life of the driving member 321.
