High-pressure fuel oil supplying device for diesel vehicle

Abstract

The invention discloses a high-pressure fuel oil supplying device for a diesel vehicle. The high-pressure fuel oil supplying device is arranged on the inner side of a steel plate spring of the diesel vehicle, and comprises a plunger pump swinging arm, a plunger oil pump, a plunger pump oil inlet one-way valve, an oil tank, a high-pressure oil pump, a high-pressure oil pump oil conveying one-way valve, a plunger pump oil conveying one-way valve, a fuel oil pressure-limiting valve, a nozzle and a pressure sensor. Due to the adoption of the high-pressure fuel oil supplying device, the working time of the high-pressure oil pump can be shortened, and the energy consumption of an oil supplying system is reduced; the vibration of the vehicle can be absorbed, and mechanical energy is transformed into hydraulic energy; plunger pumps on both sides are used for supplying oil simultaneously, so that continuous oil supplying is ensured; the oil supplying pressure is constant, and work is reliable; and moreover, the structure is simple, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a diesel vehicle component, in particular to a high-pressure fuel supply device for a diesel vehicle. Background technique [0002] At present, the fuel supply system of diesel vehicles generally uses a high-pressure oil pump to supply fuel to the engine. Since the high-pressure oil pump is driven by the cam rotation of the engine, the non-stop working fuel supply system will consume a considerable part of the energy of the diesel vehicle. In addition, during the normal driving of diesel vehicles, there are always up and down vibrations and shocks, and the ride comfort is relatively poor. Contents of the invention [0003] The object of the present invention is to provide a high-pressure fuel supply device for diesel vehicles to address the deficiencies in the prior art. [0004] The object of the present invention is achieved through the following technical solutions: a high-pressure fuel supply device for diesel vehicles, ...
