embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, air-intake of combustion engine mechanism with orientation nozzle described in the utility model comprises air intake duct 1 and gas distribution pipe 2, described air intake duct is provided with the intake manifold 3 being communicated with inlet cylinder, described gas distribution pipe 2 is arranged in the inner chamber of described air intake duct 1, the tube wall of air intake duct 1 is fitted with the blast tube pipe 4 being communicated with gas distribution pipe 2.Combustion gas injects gas distribution pipe 2 by blast tube pipe 4, and controls burner oil in air intake duct 1 by injection control valve 6.
The tube wall of described air intake duct 1 is provided with valve seat 5.As shown in Figure 2 and Figure 3, described valve seat 5 comprises outer tube body 51 and the interior tube body 52 of coaxial setting, and the center of described outer tube body 51 and interior tube body 52 is provided with the cylindrical cavity holding injection control valve.
Described outer tube body 51 is fixedly inserted on the tube wall of air intake duct 1, and described interior tube body 52 is fixedly inserted on the tube wall of gas distribution pipe 2, namely between the interspersed tube wall being arranged on air intake duct 1 and gas distribution pipe 2 of valve seat 5.Valve seat 5 between the tube wall and the tube wall of gas distribution pipe 2 of air intake duct 1 is provided with combustion gas arm mounting hole 53 and safety vent 54; Injection control valve 6 is inserted in valve seat 5, and the inner inlet end of described injection control valve 6 is arranged in the inner chamber of gas distribution pipe 2, and the outlet side correspondence of described injection control valve 6 is communicated with combustion gas arm mounting hole 53; Described combustion gas arm mounting hole 53 is installed with combustion gas arm 7.The end of combustion gas arm 7 is arranged in intake manifold 3, and the fuel sprayed by injection control valve 6 by combustion gas arm 7 is guided and enters intake manifold 3.Like this, no matter where injection control valve 6 is in, and can change injection direction by combustion gas arm 7, makes fuel spray into intake manifold 3 all the time.
Certainly, if the structure of injection control valve 6 shell is convenient to fixed installation, also without valve seat 5, directly injection control valve 6 can be interted and is arranged on the tube wall of air intake duct 1 and gas distribution pipe 2.As long as make the inlet end of injection control valve 6 be arranged in the inner chamber of described gas distribution pipe 2, the outlet side of injection control valve 6 is arranged in the inner chamber of the outside of gas distribution pipe 2, air intake duct 1.
