Embodiment Construction

[0017] exist figure 1 , 2 In the four-cylinder engine intake manifold embodiment shown in , 3 and 4, an engine intake manifold includes an upper body that collects flow and a lower body that disperses flow. The upper body has an air inlet 1, a resonance cavity 2 and a set of bent upper body tubes 3; the lower body has a set of lower body tubes 7 adapted to the bent upper body tubes 3, and electrospray holes 8 And air outlet 9. The upper body is also provided with a sensor mounting hole 6, a crankcase ventilation pipe joint 4 and a vacuum pipe joint 5, and a group of bent upper body pipes 3 are arranged in parallel. The crankcase ventilation pipe joint 4 is located in the middle of the upper body, and the vacuum pipe joint 5 is located at the tail end of the upper body.

[0018] Such as image 3 As shown, the angle between the electrospray hole 8 and the vertical plane is 13--15°.

Abstract

An air inlet manifold of engine consists of flow concentration top body and flow dispersion bottom body. It is featured as setting air inlet and resonant cavity as well as a group of folded top body tube on said top body, setting air outlet and electric jet hole as well as bottom body tube adapting to top body tube on said bottom body, also setting erection hole of transducer and vacuum pipe fittings as well as air ventilation pipe fitting of crankcase on said top body, and setting a group of folded top body tube to be in parallel way.

Description

technical field [0001] The invention relates to an engine intake manifold, in particular to a centrally controlled multi-cylinder engine intake manifold. Background technique [0002] At present, the structure of the traditional engine intake manifold is that a group of dredging air pipes are drawn radially from the resonance cavity of the collector upper body. Its shortcomings are that the airflow entering each cylinder (especially those with four or more cylinders) is not uniform, the eddy current generated by each cylinder is not uniform, and the angle of the electric injection hole of each cylinder is not easy to control, resulting in the decline of injection quality and poor combustion. Emissions worsened. Moreover, the traditional engine intake manifold does not have various sensor mounting holes necessary for modern centrally controlled multi-cylinder engines. Contents of the invention [0003] The present invention solves the existing technical problems such as u...
