Problems solved by technology

If another fuel needs to be used at the same time, the existing method is to set an injection hole in the intake manifold resonant cavity to connect the nozzle of the second fuel. This structural design is relatively simple, but because it is a single-point injection, the fuel consumption Large; some also modify the intake manifold, drill a hole in the middle of the intake manifold air passage, and install the nozzle of the second fuel, so that the injection angle of the nozzle is not easy to control, the best injection effect cannot be achieved, and it is easy to cause fuel waste

Embodiment Construction

[0013] Below in conjunction with accompanying drawing, specifically set forth the structure of the present invention;

[0014] Referring to Fig. 1, the dual-fuel intake manifold includes an intake manifold air passage 2 and an intake manifold flange 4, above and below the intake manifold air passage 2 and close to the intake manifold flange A first-type fuel nozzle mounting step 1 and a second-type fuel nozzle mounting step 2 are respectively integrally cast on the plate.

[0015] Referring to FIG. 2 , the first fuel nozzle installation step 1 is processed with a first fuel nozzle common rail installation hole 5 and a first fuel nozzle installation hole 6 . The air pipe of the first fuel is fixed through the nozzle common rail installation hole 5 of the first fuel, and its nozzle is installed in the nozzle installation hole 6 of the first fuel.

[0016] Referring to Fig. 3, nozzle common rail installation holes 7 for the second fuel and nozzle installation holes 8 for the sec...

Abstract

The intake manifold for double fuel engine includes one intake manifold gas passage and one intake manifold flange, one first fuel nozzle mounting stage with first fuel nozzle installing holes over the intake manifold gas passage, and one first fuel nozzle mounting stage with second fuel nozzle installing holes below the intake manifold gas passage. The present invention realizes the installation of nozzles for two different kinds of fuel, and has simple structure and easy manufacture.

Description

technical field [0001] The invention belongs to the technical field of automobile engines. Background technique [0002] With the diversification of fuel sources for automobile engines, in order to adapt automobile engines to different fuels, it is very necessary to adapt the engine to different fuels in the simplest and cheapest way. At present, fuel for internal combustion engines comes from the injection of fuel nozzles installed on the intake manifold. The nozzles are generally arranged directly above the intake manifold, and the nozzles generally can only provide injection of one type of fuel. If another fuel needs to be used at the same time, the existing method is to set an injection hole in the intake manifold resonant cavity to connect the nozzle of the second fuel. This structural design is relatively simple, but because it is a single-point injection, the fuel consumption Large; some also modify the intake manifold, drill a hole in the middle of the intake manifo...
