Description

Technical Field

[0001] This utility model belongs to the technical field of diesel engines, specifically relating to a fuel injection system fuel bubble emission regulating device for diesel engines. Background Technology

[0002] The advantages of diesel engines are high torque and good fuel economy. The working process of a diesel engine is similar to that of a gasoline engine in many ways, with each working cycle also involving four strokes: intake, compression, power, and exhaust.

[0003] Existing diesel engine fuel injection systems produce air bubbles during operation. These air bubbles can affect the normal operation of the system, leading to unstable pressure, noise, or component damage. They require manual periodic venting, which is cumbersome. Therefore, it is necessary to design a fuel bubble venting and regulating device for diesel engine fuel injection systems. Utility Model Content

[0004] The purpose of this invention is to provide a fuel line bubble emission regulating device for a diesel engine fuel injection system, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fuel injection system oil circuit bubble emission regulating device for diesel engines includes an installation cylinder assembly, an anti-splash assembly provided on the inner wall of the installation cylinder assembly, an exhaust assembly provided on the top of the installation cylinder assembly, and a spike rod assembly provided on the bottom of the anti-splash assembly.

[0007] The splash guard assembly includes a hanging rod, and a spiral splash guard plate is fixedly connected to the outer wall of the hanging rod. Through the installation of the splash guard assembly, and in conjunction with the mounting cylinder assembly, spike rod assembly, and exhaust assembly, in use, firstly, the adjusting device is installed at the highest point or a relatively high position on the injection system's oil circuit via the lower connecting cylinder thread at the bottom of the mounting cylinder. When bubbles generated in the system's oil circuit rise with vibration, they automatically dissipate at the connection between the mounting cylinder assembly and the injection system or are punctured by the bubble-piercing needle, releasing the gas in the bubbles. This increases the air pressure inside the mounting cylinder. When the micro barometer detects that the air pressure has increased to a certain value, the micro barometer sends a signal to the central control system on the external vehicle, controlling the opening of the control valve to release pressure inside the mounting cylinder, thereby maintaining a stable state in the system's oil circuit.

[0008] By setting up anti-splash components, including spiral anti-splash plates, a good shielding and anti-splashing effect can be achieved for diesel fuel during driving, stabilizing the state of the oil body inside the system's oil circuit;

[0009] By setting up the exhaust assembly, in which the control valve and the miniature barometer work together, the internal oil circuit of the system can be monitored in real time, thereby achieving the effect of timely control of the control valve to exhaust, so that the oil circuit of the system is kept within a stable air pressure range.

[0010] By setting up the puncture rod assembly, including the bubble-piercing needle, bubbles that cannot dissipate in time in the system oil circuit can be punctured, thereby facilitating the subsequent processing of the gas in the bubbles.

[0011] The mounting cylinder assembly includes a mounting cylinder, the top of which has a hanging groove, and the bottom of which is fixedly connected to a lower connecting cylinder.

[0012] The exhaust assembly includes a splash guard, and a control valve is disposed above the splash guard;

[0013] The spiked rod assembly includes a mounting rod, the outer wall of which is threadedly connected to a screw cylinder, and the inner wall of which is threadedly connected to a puncture needle.

[0014] As a preferred embodiment of this utility model, the number of hanging rods is two, and the two hanging rods are arranged symmetrically.

[0015] As a preferred embodiment of this utility model, the number of hanging slots is also two, and the inner wall of the hanging slot is fitted and connected to the outer wall of the hanging rod.

[0016] As a preferred embodiment of this utility model: the inner wall of the splash-proof top is vertically provided with an exhaust hole, and the control valve is located on the inner wall of the exhaust hole.

[0017] As a preferred embodiment of this utility model: the splash-proof top and the mounting cylinder are fixedly connected by bolts, and the top is positioned between the splash-proof top and the mounting cylinder and pressed tightly by the splash-proof top.

[0018] As a preferred embodiment of this utility model: a miniature barometer is installed inside the splash-proof top, and the miniature barometer is located below the control valve.

[0019] As a preferred embodiment of this utility model: the bottom of the spiral splash guard is provided with several mounting holes, and the inner wall of the mounting holes is provided with threaded grooves, and the inner wall of the mounting holes is threadedly connected to the outer wall of the mounting rod.

[0020] As a preferred embodiment of this utility model: the outer wall of the lower connecting cylinder is provided with an installation thread groove, and one end of the outer wall of the lower connecting cylinder is chamfered.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by setting the anti-splash component, the spiral anti-splash plate can achieve a better shielding and anti-splashing effect on diesel fuel during driving, and stabilize the state of the oil body inside the system oil circuit.

[0022] By setting up the exhaust assembly, in which the control valve and the miniature barometer work together, the internal oil circuit of the system can be monitored in real time, thereby achieving the effect of timely control of the control valve to exhaust, so that the oil circuit of the system is kept within a stable air pressure range.

[0023] By using the puncture rod assembly, including the bubble-piercing needle, bubbles that cannot dissipate in time in the system's oil circuit can be punctured, thereby facilitating the subsequent processing of the gas within the bubbles. Attached Figure Description
