Problems solved by technology

[0003] In the design of automobile fuel supply system, due to the limitations of boundary conditions, the fuel tank is designed to be flat and relatively long. At this time, if the car is on a certain slope, the oil suction pipe in the fuel tank may not be able to suck the oil in the fuel tank. Fuel, in extreme cases may cause the engine to stall, which will affect some functions of the vehicle and seriously affect the safety of the vehicle

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 As shown, in order to ensure that the fuel 102 in the main fuel tank body 11 can be smoothly absorbed when the vehicle goes uphill, the oil suction pipe 13 is usually arranged behind the main fuel tank body 11 (with the forward direction of the vehicle as the front, figure 1 The direction of the middle arrow is the forward direction of the vehicle), so as to ensure that the fuel 102 can be sucked uphill.

[0027] When the car is on a slope with a slope of α, when going downhill, the fuel 102 flows to one side due to gravity, even if there is half a tank of fuel in the main fuel tank body 11 at this time, there is still no fuel available near the oil suction pipe 13, and the engine cannot absorb fuel. In extreme cases, it may cause the engine to stall, which will affect some functions of the vehicle and seriously affect ...

Abstract

The invention relates to automobile oil supplying systems, in particular to an oil supplying system of a slope self-adaption diesel engine. The oil supplying system comprises a main oil tank assembly,an isolation plate is arranged in the main oil tank body, the main oil tank body is divided into a first oil cavity including an oil suction pipe and a second oil cavity including an oil delivery pump assembly by the isolation plate, the oil delivery pump assembly is communicated with the first oil cavity through an oil pipe to pump fuel oil in the second oil cavity into the first oil cavity, sothat it is ensured that the periphery of the oil suction pipe is always filled with the fuel oil, and normal fuel oil supplying of the engine is ensured; the interior of the main oil tank body is divided into the first oil cavity including the oil suction pipe and the second oil cavity including the oil delivery pump assembly by the isolation plate, a single-way valve is arranged on the isolationplate to allow the fuel oil in the fuel tank to flow only from one end of the oil delivery pump to the end provided with the oil suction, the fuel oil in the fuel oil tank is prevented from flowing from the end provided with the oil suction pipe to one end of the oil delivery pump assembly, and the normal fuel oil supplying of the engine is further ensured.

Description

technical field [0001] The invention relates to an automobile fuel supply system, in particular to a gradient adaptive diesel engine fuel supply system. Background technique [0002] In the design of automobile fuel supply system, usually, in order to ensure that the fuel can be smoothly absorbed into the fuel tank when the vehicle goes uphill, the fuel suction pipe is usually arranged behind the fuel tank (with the forward direction of the vehicle as the front, the same below), so as to Make sure you can get fuel uphill. [0003] In the design of automobile fuel supply system, due to the limitations of boundary conditions, the fuel tank is designed to be flat and relatively long. At this time, if the car is within a certain slope, the oil suction pipe in the fuel tank may not be able to suck the oil in the fuel tank. Fuel, in extreme cases, may cause the engine to stall, which will affect some functions of the vehicle and seriously affect the safety of the vehicle. Conte...
