Problems solved by technology

[0004] 1) The contact area between the bracket and the cylinder head cover is small, and the installation position of the nozzle on the bracket is far from the installation position of the bracket itself, not only the stability of the nozzle support is poor, but also affected by the engine vibration, the back plate and the The lower vertical plate is prone to breakage and has a short service life
[0005] 2) The connecting line between the nozzle installation hole and the center of the positioning notch is on the same horizontal line, and the opening of the positioning notch faces the horizontal direction, so the positioning effect of the nozzle is poor, and it is easy to cause the nozzle to loosen or fall off
[0006] 3) The overall structure is complex, the processing and manufacturing processes are many, and the production cost is relatively high

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0022] like figure 1 , figure 2 and image 3 As shown, the nozzle bracket of an automobile engine has a frame body 1, which is formed by stamping a plate, and is composed of side plates 1a symmetrically arranged on the left and right sides and a bottom plate 1b at the bottom. The side plate 1a is perpendicular to the bottom plate 1b, and the side plate 1a The bottom of the bottom is connected with the end of the bottom plate 1b. The middle part of the bottom plate 1b is deformed and arched upwards to increase the structural strength of the bottom plate 1b and prevent the bottom plate 1b from being deformed. There are two left-right symmetrical bracket installation holes 4 on the base plate 1b. These two bracket installation holes 4 are separated on both sides of the arched part in the middle of the base plate 1b, and each bracket installation hole 4 is c...

Abstract

The invention discloses a mounting bracket for a fuel gas nozzle of an automobile engine, and the mounting bracket comprises a bracket body (1), wherein the bracket body (1) is composed of side plates (1a) which are symmetrically arranged at the left side and the right side and a base plate (1b) at the bottom, the side plates (1a) and the base plate (1b) are vertically connected, the base plate (1b) is provided with two bracket mounting holes (4) which are in bilateral symmetry, and each bracket mounting hole (4) is close to the side plate (1a) at the corresponding side, a locating notch (6) is arranged at the top of each side plate (1a), and the opening of the locating notch (6) is upfront; and each side plate (1a) is also provided with a nozzle mounting hole (5), and the nozzle mounting hole (5) is arranged at the lower rear of the locating notch (6). The mounting bracket disclosed by the invention is firmly and reliably arranged on a cylinder head cover, does not crack, can be used for firmly supporting the nozzle and effectively preventing the nozzle from loosening or dropping and has the characteristics of simple modelling, easiness for processing and manufacturing and low production cost.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and in particular relates to a gas nozzle mounting bracket on an automobile engine. Background technique [0002] At present, a common rail gas nozzle is installed on a vehicle gas engine or a fuel-gas dual-fuel engine. . [0003] The existing gas nozzle mounting bracket such as Figure 4 , Figure 5 As shown, it consists of side frames 2 arranged symmetrically on the left and right sides and a beam 3 connecting the two side frames 2. The side frame 2 is composed of an upper vertical plate 2a, a middle horizontal plate 2b, a lower vertical plate 2c and a back plate 2d. The upper vertical plate 2a is located above the lower vertical plate 2c, and the two are parallel. The upper vertical plate 2a and the lower vertical plate 2c are connected through the middle horizontal plate 2b, and the upper vertical plate 2a is perpendicular to the middle horizontal plate 2b. Cross beams 3 are wel...
