The straight air track comprises an air track lower block, wherein an air track upper block is mounted on the air track lower block, at least two injection valves are mounted between the air track upper block and the air track lower block, a gas outlet which is communicated with an air inlet pipe of the engine is arranged on the air track upper block, a fixing device is arranged on the air track lower block, the lateral portion of the air track lower block is fixedly connected with an air track joint, and a gas inlet is arranged on the air track joint. The bottom of the air track lower block is provided with a bottom surface threaded hole, disassembly, assembly and maintenance are extremely convenient, when a nozzle connector is connected, the installation of a nozzle plug is not influenced, and bottom fixation is beneficial for reducing the vibrating stress of the air track, and the disassembly, assembly and maintenance are convenient.
Description
Technical field
The utility model relates to technical field of engines, relates in particular to a kind of fixing device for installing of engine spray valve.
Background technique
For motor, the function of injection valve is that the control fuel gas injection burns in suction tude or firing chamber, and existing mounting structure normally is distributed on injection valve on the gas rail, the gas rail is fixed on the cylinder cover of engine by master bracket again.Like this, just do not have the space to increase the constraint point that is connected with cylinder head cover between four air valves, rely on simply that two bolts hole are connected with cylinder head cover on the master bracket, it is excessive to connect span, can cause whole system rigidity very low, very easily produce resonance, thereby cause the support fracture failure.
The model utility content
Technical problem to be solved in the utility model provides a kind of easy accessibility, and the gas rail is subjected to the little gas engine of vibration stress with gas rail in upright arrangement.
For solving the problems of the technologies described above, the technical solution of the utility model is: gas engine is with gas rail in upright arrangement, comprise piece under the gas rail, on the piece piece on the gas rail is installed under the described gas rail, between the piece at least two injection valves are installed under piece and the described gas rail on the described gas rail, piece is provided with the gas outlet that is communicated with engine air inlet tube on the described gas rail, and piece is provided with fixing device under the described gas rail; The sidepiece of piece is fixedly connected with gas rail joint under the described gas rail, and described gas rail joint is provided with fuel gas inlet.
As a kind of embodiment, described fixing device is the bottom surface screw that is arranged at piece bottom surface under the described gas rail.
As a kind of embodiment, described fixing device also comprises the side fixed hole that is arranged on piece side under the described gas rail.
As a kind of embodiment, described side fixed hole is triangularly arranged on the side of piece under the described gas rail.
As a kind of embodiment, under described gas rail joint and the described gas rail between the piece bolt be connected.
As a kind of embodiment, described injection valve is a solenoid valve.
As a kind of embodiment, described injection valve is 12.
Owing to adopted technique scheme, the bottom of piece is provided with bottom surface screw, fixation under described gas rail, dismounting is safeguarded very convenient, when the nozzle connector assembly is installed, do not influence nozzle insert and install, and the bottom is fixed with to be beneficial to and reduces the vibration stress that the gas rail is subjected to.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the utility model embodiment's a plan view;
Fig. 2 is the utility model embodiment's a plan view;
Fig. 3 is the utility model embodiment's a worm's eye view;
Fig. 4 is the utility model embodiment's a right elevation;
Among the figure: 1. piece on the gas rail, 2. piece under the gas rail, 3. gas rail joint, 4. fuel gas inlet, 5. gas outlet, 6. injection valve, 7. bottom surface screw, 8. side fixed hole, 9. bolt.
Embodiment
As shown in Figures 1 to 4, a kind of gas engine is with gas rail in upright arrangement, comprise piece 2 under the gas rail, piece 1 on the gas rail is installed on the piece 2 under the described gas rail, between the piece 2 at least two injection valves 6 are installed under piece 1 and the described gas rail on the described gas rail, described injection valve 6 is a solenoid valve, in the present embodiment, be provided with 12 injection valves 6, described 12 injection valves 6 are divided into two rows and arrange and to be installed on the described gas rail under the piece 1 gentle rail between the piece 2.Piece 1 is provided with the gas outlet 5 that is communicated with engine air inlet tube on the described gas rail, and piece 2 is provided with fixing device under the described gas rail; Described fixing device is the bottom surface screw 7 that is arranged at piece 2 bottom surfaces under the described gas rail; Described fixing device also comprises the side fixed hole 8 that is arranged on piece 2 sides under the described gas rail, and described side fixed hole 8 is triangularly arranged on the side of piece 2 under the described gas rail.The sidepiece of piece 2 is fixedly connected with gas rail joint 3 under the described gas rail, and described gas rail joint 3 is provided with fuel gas inlet 4.Under described gas rail joint 3 and the described gas rail between the piece 2 bolt 9 fixedly connected.
During work, combustion gas enters gas engine with gas rail in upright arrangement via the fuel tube that is connected with fuel gas inlet 4, is full of piece 2 under the gas rail joint 3 gentle rails.On gas rail joint 2, the gaseous-pressure temperature transducer is installed, ECU is according to the gaseous-pressure temperature signal and the motor operation conditions that receive, calculate needed gas quantity, injection pulse width by control injection valve 6, with needed fuel gas injection piece 1 to the gas rail, get the needed combustion gas of engine running up till now, the combustion gas that is injected into piece 1 on the gas rail enters engine air inlet tube via fuel tube.In the present embodiment, adopt 12 nozzle mounting holes, 12 nozzles can be installed, the operating time of each nozzle shortens, frequency of okperation diminishes, and helps improving gas rail working life.This gas engine adopts aluminum alloy material with gas rail in upright arrangement, and is in light weight, is easy to dismounting and safeguards.
All are from design of the present utility model, and the structure conversion of having done without creative work all drops within the protection domain of the present utility model.
