Description

Technical Field

[0001] The invention relates to a saddle-shaped oil tank with a dual-channel EUC controller, and mainly relates to the field of oil pump control. Background Art

[0002] In usage scenarios such as saddle-shaped fuel tanks, two fuel pumps are usually required to transport gasoline. Currently, a common solution is to use one controller for one fuel pump to drive the controller. On the one hand, this solution will increase the cost of the controller. On the other hand, the space occupied by an additional controller will also increase significantly. Summary of the invention

[0003] In view of the above deficiencies in the prior art, the present invention proposes a saddle-shaped oil tank with a dual-channel EUC controller, which adopts one controller electrically connected to two oil pumps and controls the two oil pumps through control logic, thereby saving space and manufacturing costs.

[0004] To achieve the above object, the technical solution of the present invention is: a saddle-shaped oil tank with a dual-channel EUC controller, comprising a saddle-shaped oil tank and two oil pumps;

[0005] The two oil pumps are respectively located in the two compartments of the saddle-shaped oil tank, and the output ends of the two oil pumps are respectively connected to the main pipe through a one-way valve, and the one-way valve only allows oil to flow from the oil pump to the main pipe. The main pipe is provided with a filter and is connected to the oil rail; the two oil pumps are electrically connected in parallel to the controller, and the controller is connected to the ECU through a CAN bus cable.

[0006] The technical principles and beneficial effects of the present invention are as follows:

[0007] This solution uses a controller to connect two oil pumps electrically, and controls the two oil pumps through control logic, which saves more space and manufacturing costs. A one-way valve is set between the two oil pumps and the main pipe, which can effectively prevent oil from flowing to the other oil pump and can supply oil to the oil rail more stably.

[0008] Preferably, the main pipe is provided with a high-pressure pump.

[0009] Preferably, an oil pressure sensor is provided in the pipeline between the high-pressure pump and the oil pump, and the oil pressure sensor is electrically connected to the ECU.

[0010] Preferably, the oil pressure sensor is a ceramic oil pressure sensor.

[0011] Preferably, the model of the oil pressure sensor is CPS181.

[0012] Preferably, a high-pressure pressure sensor is provided between the high-pressure pump and the oil rail, and the high-pressure pressure sensor is electrically connected to the ECU.

[0013] Preferably, the controller is electrically connected to a power source.

[0014] Preferably, the controller adopts the model of Curtis AC F2-A. BRIEF DESCRIPTION OF THE DRAWINGS
