Embodiment Construction

[0017] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] As shown in the figure, a one-piece injector includes an injector body, and the injector body is equipped with:

[0019] The first fuel inlet 11 is used to connect with the first fuel supply pipeline, such as gasoline fuel supply pipeline;

[0020] The second fuel inlet 12 is arranged in parallel with the first fuel inlet, and is used for connecting with a second fuel supply pipeline, such as a methanol fuel supply pipeline;

[0021] The first control chamber 21 communicates with the first fuel inlet 11 and the second fuel inlet 12;

[0022] The second control c...

Abstract

The embodiment of the invention discloses an integrated ejector. The integrated ejector comprises an ejector body. The ejector body is provided with a first fuel inlet, a second fuel inlet, a first control cavity communicated with the first fuel inlet and the second fuel inlet, a second control cavity communicated with the first control cavity, a fuel ejecting port communicated with the second control cavity, a fuel switching control valve arranged in the first control cavity and used for controlling switch between first fuel feeding and second fuel feeding, and a fuel ejection control valve arranged in the second control cavity and used for controlling the second control cavity to be communicated with or disconnected from the fuel ejection port. The integrated ejector is simple in structure and convenient to install, and fuel switching can be conducted smoothly. Furthermore, the integrated ejector can directly replace an original automotive ejector to be installed at the position where the original automotive ejector is located, the optimal ejection angle can be obtained, and oil consumption can be reduced. Besides, oil film deposition and covering can be avoided.

Description

Technical field: [0001] The invention relates to a dual-fuel integral injector. Background technique: [0002] With the focus on vehicle economy and alternative fuel economy and environmental protection, automakers and refitting markets turn to more economical and environmentally friendly vehicles in order to improve efficiency and energy conservation and environmental protection, so the effective use of alternative fuels or dual-purpose fuels or multiple fuels use, requires a unique configuration of traditionally fueled engine components. [0003] In order to adapt to the mixed use of multiple fuels or the selective switching of use, dual-fuel or multi-fuel economical and environmentally friendly vehicles that are refitted or produced are generally based on the original vehicle, and the intake manifold is refitted with new fuel connected to the intake manifold. The injector, the original vehicle fuel injector and the newly added fuel injector are mutually independent split...
