Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, engine gas multi-point sequence injection device of the present invention includes gas header pipe 1, one end of described gas header pipe 1 is provided with fuel gas inlet 9, the tube wall of gas header pipe 1 is provided with the gas outlet 2,3,4,5,6,7 of multiple connection engine gas jet, and the quantity of gas outlet is corresponding with the number of cylinders of electromotor.nullIt is set with gas distribution pipe 8 in described gas header pipe 1，The outer wall of described gas distribution pipe 8 rotatably seals with the inwall of gas header pipe 1 and coordinates，Gas distribution pipe 8 is towards the one end open of fuel gas inlet 9、The other end is provided with the rotary drive mechanism driving gas distribution pipe 8 to rotate and the axial actuating mechanism driving gas distribution pipe 8 to move axially，The tube wall of gas distribution pipe 8 is provided with corresponding to gas outlet 2、3、4、5、6、The combustion gas dispensing orifice 21 of 7、31、41、51、61、71,Described combustion gas dispensing orifice 21、31、41、51、61、71 are circumferentially distributed around gas distribution pipe 8，Each combustion gas dispensing orifice 21、31、41、51、61、Axial spacing between 71 and each gas outlet 2、3、4、5、6、Axial spacing between 7 is equal.
Sealing mechanism between gas distribution pipe 8 with gas header pipe 1 can use as it is shown in figure 1, arrange annular groove on gas distribution pipe outer wall between adjacent two combustion gas dispensing orifices, installs sealing ring 10 in annular groove.Other can also be used to seal structure, as long as adjacent two combustion gas dispensing orifices and gas outlet can be separated, the most do not affect the rotation of gas distribution pipe 8 and move axially simultaneously.
The timing gears 82 that described rotary drive mechanism is mounted on engine cam, the end of described gas distribution pipe 8 is installed with travelling gear 81, and described travelling gear 81 is in transmission connection with timing gears 82.The when of electromotor work, camshaft drives timing gears 82 to rotate, timing gears 82 drive again gas distribution pipe 8 to rotate, the work schedule of electromotor difference cylinder is corresponding with combustion gas dispensing orifice position on gas distribution pipe 8, successively combustion gas dispensing orifice can be docked with gas outlet when that gas distribution pipe 8 rotating, and to the gas outlet injection combustion gas of docking.
Described axial actuating mechanism is provided in the cam 83 of gas distribution pipe 8 one end.The size of lap when driving gas distribution pipe 8 to move axially that i.e. adjustable fuel gas dispensing orifice docks with gas outlet by axial actuating mechanism, thus change fuel gas injection amount.
For accurately controlling injecting time and the emitted dose of combustion gas, the angle that sensor detection gas distribution pipe 8 rotates and the position moved axially can also be set, and the position signalling of gas distribution pipe 8 is delivered to spraying fire mechanism 84, more accurately controlled the running parameter of electromotor by spraying fire mechanism 84.
