Referring to Figures 1-3 The gas supply system provided in the embodiment comprises a plurality of modular gas supply units 1, and in the embodiment, the modular gas supply unit 1 is specifically three.

[0046] Specifically, the modular gas supply unit 1 comprises a pressure stabilizing chamber 100, an adjusting mechanism 200, and a gas delivery mechanism 300. The pressure stabilizing chambers 100 of a plurality of the modular gas supply units 1 are connected in series and communicate with each other, and the pressure stabilizing chamber 100 contains gas. The adjusting mechanism 200 is arranged at the gas outlet of the pressure stabilizing chamber 100. The gas delivery mechanism 300 is selectively connected to the pressure stabilizing chamber 100 through the adjusting mechanism 200, and the gas delivery mechanism 300 is connected to a plurality of pre-combustion chambers 10 and can deliver the gas in the pressure stabilizing chamber 100 to each pre-combustion chamber 10. The adjusting mechanism 200 can adjust the gas pressure of each pre-combustion chamber 10. Through the modular design of the gas supply system for delivering gas to the multi-cylinder gas engine, according to the length of the required gas rail, a proper number of modular gas supply units 1 are selected and sequentially connected and assembled, so as to reduce the manufacturing cost and difficulty of the overall gas rail with an excessively long length. The pressure stabilizing chamber 100 is arranged to stabilize the pressure and prevent problems such as pressure fluctuation in the internal space of the gas supply system, thereby improving the consistency of the intake amount of each cylinder of the engine and improving the engine performance.

[0047] More specifically, the pressure stabilizing chamber 100 is a cavity structure with a large internal space volume, so that it has the effect of stabilizing pressure. It should be understood that the pressure stabilizing effect of the pressure stabilizing chamber 100 is related to the size of the internal space, not the internal structure. The longitudinal section of the pressure stabilizing chamber 100 can be rectangular, circular or any other shape. In this embodiment, the pressure stabilizing chamber 100 is a cuboid, and the longitudinal section of the pressure stabilizing chamber 100 is rectangular.

[0048] More specifically, the gas supply system further comprises a communication pipe 400. In a plurality of pressure stabilizing chambers 100 connected in series, the adjacent pressure stabilizing chambers 100 are detachably connected through the communication pipe 400. The communication pipe 400 can be a plug sealing pipe or the like in the prior art, and according to the actual arrangement requirements, a flexible pipe can be used to realize the arrangement mode of stacking a plurality of pressure stabilizing chambers 100, etc., to reduce the occupied space of the gas supply system.

[0049] More specifically, the gas supply system further comprises a main fuel pipe 500, which is connected to the gas source and one of the pressure stabilizing chambers 100. The main fuel pipe 500 has a large internal cavity volume, and the gas entering the main fuel pipe 500 from the gas source can stabilize the pressure after being delivered to the pressure stabilizing chamber 100 through the main fuel pipe 500.

[0050] Continuing to refer to Figure 1 The pressure stabilizing chamber 100 is provided with a pressure stabilizing pressure sensor 110, which can monitor the gas pressure in the pressure stabilizing chamber 100.

[0051] Continuing to refer to Figure 1 The gas delivery mechanism 300 comprises a plurality of gas delivery pipes 310, which are selectively connected to the pressure stabilizing chamber 100 through the adjusting mechanism 200, and each of the gas delivery pipes 310 is connected to one of the pre-chambers 10. The adjusting mechanism 200 can adjust the gas pressure in each of the gas delivery pipes 310. In this embodiment, each pressure stabilizing chamber 100 is provided with four gas outlets, which are arranged on the opposite two side walls of the pressure stabilizing chamber 100 in two groups. That is, a single pressure stabilizing chamber 100 is connected to four pre-chambers 10 at the same time.

[0052] Specifically, the gas delivery mechanism 300 further comprises a plurality of delivery pressure sensors 320. The delivery pressure sensors 320 are arranged in the gas delivery pipes 310 one by one, and can monitor the gas pressure in the gas delivery pipes 310.

[0053] In detail, the gas delivery mechanism 300 further comprises a plurality of one-way valves 330. The one-way valves 330 are arranged in the gas delivery pipes 310 one by one and downstream of the delivery pressure sensor 320. The one-way valves 330 can limit the flow direction of the gas in the gas delivery pipes 310 to be from the pressure stabilization chamber 100 to the precombustion chamber 10. By arranging the one-way valves 330, the gas in the gas delivery pipes 310 can be prevented from flowing back to the pressure stabilization chamber 100, disturbing the flow field in the pressure stabilization chamber 100, and causing the problem of gas pressure change.

[0054] With continuous reference to Figure 2 and Figure 3 The adjusting mechanism 200 comprises a plurality of gas adjusting valves 210. In the embodiment, four gas adjusting valves 210 are arranged in each modular gas supply unit 1. The four gas adjusting valves 210 are arranged at the four gas outlets of the pressure stabilization chamber 100 one by one, and each gas adjusting valve 210 is connected to a gas delivery pipe 310. The opening degree of the gas adjusting valve 210 can be adjusted, thereby realizing the control of the gas intake amount of the precombustion chamber 10 and the control of the gas pressure of the precombustion chamber 10. By arranging the gas adjusting valve 210 between each gas delivery pipe 310 and the pressure stabilization chamber 100, the individual control of the plurality of gas delivery pipes 310 can be realized, and the precise control of the gas intake amount of the four precombustion chambers 10 corresponding to the pressure stabilization chamber 100 can be improved.

[0055] In detail, the gas adjusting valve 210 comprises an adjusting valve body (not shown in the figure). The adjusting valve body is arranged between the pressure stabilization chamber 100 and the gas delivery pipe 310, and a flow channel can be formed inside to allow the gas to flow. The adjusting valve body can control the opening and closing of the flow channel, that is, the connection and disconnection between the pressure stabilization chamber 100 and the gas delivery pipe 310. The adjusting valve body can also control the opening degree of the flow channel by its action, thereby controlling the gas amount of the gas flowing to the gas delivery pipe 310 through the gas adjusting valve 210. The adjusting valve body can be selected as an electromagnetic valve and the like, which can be opened and closed and the opening degree can be controlled. It is a prior art, and its structure and principle will not be described here.

[0056] In detail, the gas adjusting valve 210 further comprises a housing 211 and a gas joint 212. The housing 211 is fixed to the outer wall of the pressure stabilization chamber 100 by a connecting member such as a bolt. The adjusting valve body is arranged in the housing 211, and the gas joint 212 is arranged on the side of the housing 211 away from the pressure stabilization chamber 100 and is connected between the gas delivery pipe 310 and the adjusting valve body. By arranging the housing 211, the adjusting valve body inside can be protected, the service life can be improved, and gas leakage can be prevented.

[0057] More specifically, the gas joint 212 specifically comprises coaxially arranged first and second connecting portions. The first connecting portion penetrates the housing 211 and is connected to the regulating valve body by means of plug-in connection, and the second connecting portion is capable of being connected to the end of the gas delivery pipe 310 by means of plug-in connection.

[0058] With continuous reference to Figure 1 The gas supply system further comprises a control unit. The steady pressure sensor 110, the delivery pressure sensor 320 and the gas regulating valve 210 are respectively communicatively connected to the control unit. The control unit is capable of receiving the pressure signal of the corresponding steady pressure chamber 100 sent by the steady pressure sensor 110, and is also capable of receiving the pressure signal of the corresponding gas delivery pipe 310 sent by the delivery pressure sensor 320, and controls the gas regulating valve 210 according to the above-mentioned pressure signals, adjusts the opening degree of the regulating valve body, and further adjusts the intake air pressure of each pre-chamber 10. The control unit provided in the embodiment can be a vehicle ECU.

[0059] The working process of the gas supply system provided in the embodiment is as follows:

[0060] The gas enters the steady pressure chamber 100 of the first modular gas supply unit 1 from the main fuel pipe 500, and then gradually enters the steady pressure chamber 100 of each modular gas supply unit 1. At this time, the steady pressure sensors 110 of the plurality of steady pressure chambers 100 simultaneously acquire the pressure signals of the corresponding steady pressure chambers 100, and the gas after steady pressure of the steady pressure chambers 100 is branched to the corresponding plurality of gas delivery pipes 310, and then the delivery pressure sensors 320 are used to acquire the pressure signals in each gas delivery pipe 310 after steady pressure branching.

[0061] If the pressures in the plurality of gas delivery pipes 310 are consistent within an error range and are consistent with the pressures of the corresponding steady pressure chambers 100, it indicates that the air pressures in each pre-chamber 10 are equivalent, and the consistency of the intake air amount of each cylinder of the engine is guaranteed.

[0062] If the pressure of one of the plurality of gas delivery pipes 310 deviates from the pressures of the remaining gas delivery pipes 310 by more than an error range, the control unit needs to control the opening degree of the gas regulating valve 210 corresponding to the gas delivery pipe 310 with pressure deviation until the pressures in the plurality of gas delivery pipes 310 are consistent within an error range.

[0063] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
