Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0040] figure 1 A schematic structural diagram of a fuel pressure stabilizer according to an embodiment of the present invention is shown. figure 2 show figure 1 A schematic diagram of the cross-sectional structure shown in A-A. refer to figure 1 or figure 2 An embodiment of a fuel pressure stabilizer is shown, which includes a stabilizer body 101 on which an elastic structural part 102 for pressure adjustment through expansion or contraction is arranged. Through the elastic structure part 102, the fuel dynamic pressure changes and fluctuations on the inside and outside of the stabilizer body 101 can be expanded or stretched accordingly, thereby changing the volume of the fuel volume chamber, so as to realize the stability of the fuel pressure in the pressure chamber. .

Abstract

The invention discloses a fuel pressure stabilizer and a fuel jetting device thereof. The fuel pressure stabilizer comprises a stabilizer body which is provided with an elastic structural part which extends or retracts to adjust the pressure. The section of the elastic structural part is characterized in an S-shaped structure which is a curve or combination of curves. The inner ring elastic structural part characterized in the S-shaped structure in the section can extend or retract micro fuel pressure differences on inner and outer sides of a metal film in real time to change the volume of a fuel volume cavity so as to maintain the stable fuel pressure in a fuel cavity, so the stability and the precision of single jetting amount of fuel by the fuel jetting system as well as consistency among multiple jettings are ensured.

Description

technical field [0001] The present invention relates to the technical field of fuel control, injection, transmission, pressurization, drive and discharge power devices for fuel-driven ships and vehicle engines, as well as the dynamic control of liquid fuel in hydraulic power systems, in particular to a fuel pressure stabilizer and its fuel injection system. Background technique [0002] Existing fuel-driven marine and vehicle engines generally use electronically controlled fuel injection systems. High-speed solenoid valves are key components that determine the performance of electronically controlled fuel injection systems. , or the latest gasoline direct injection. The most basic function of the engine fuel injection device is to pressurize the fuel, adjust the single fuel injection quantity and injection time, distribute the pressurized fuel reasonably to each cylinder and atomize it in the combustion chamber . During the whole process, the best control of the fuel inje...
