Abstract

The invention provides a fuel oil pump and an automobile adopting the fuel oil pump and relates to the technical field of automobile engine oil supply, in particular to the fuel oil pump and the automobile adopting the fuel oil pump. The fuel oil pump and the automobile solve the problems that when a vehicle runs on an 8-shaped road or the vehicle runs under the abnormal road conditions such as uphill and downhill, and at the moment, fuel oil in an oil storage barrel is less, the flameout phenomenon caused by deoiling of an engine can occur when the existing fuel oil pump is used. The fuel oil pump provided by the embodiment comprises an oil storage barrel, a jet pump and a drainage pipe, wherein the jet pump is fixedly arranged at the outer side of the bottom of the oil storage barrel, the drainage pipe is fixedly arranged on the inner wall of the oil storage barrel, an oil outlet of the jet pump is connected with one end of the drainage pipe, and the drainage pipe is used for making return oil flowing out from the oil outlet of the jet pump flow into the oil storage barrel through the drainage pipe.

Description

technical field [0001] The invention relates to the technical field of fuel supply for automobile engines, in particular to a fuel pump and an automobile using the fuel pump. Background technique [0002] The fuel in the car is generally stored in a closed fuel tank, and a fuel pump is installed in the fuel tank to extract the fuel in the fuel tank and deliver it to the engine. [0003] At present, the fuel pump in the prior art usually includes a permanent magnet drive motor, a pump core, and a fuel pipe connection bracket connected above the pump core. The oil pipe connection bracket is provided with a fuel delivery pipe and a fuel return pipe, and the fuel delivery pipe is connected to the pump core. At the middle position in the oil storage barrel, an oil inlet is provided at the bottom of the oil storage barrel, and an injection pump is fixed outside the bottom of the oil storage barrel, and the oil return pipe is connected to the injection pump. [0004] After the per...
