Existing intake manifold is subjected to the influence of manifold inwall resistance in air enters into tracheae the time, has hindered the circulation of air; And the linkage structure of the each several part of manifold is insecure, often breaks down; The strong structural strength of the voltage stabilizing of manifold is lower, is difficult to satisfy the requirement of engine booster degree.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the intake manifold of a kind of structural strength height, motor that the air ventilation resistance is little.
The purpose of this utility model can realize by following technical proposal:
The intake manifold of this motor, comprise in a tubular form pressure stabilizing cavity, be arranged on the air intake branch that the pressure stabilizing cavity sidepiece is communicated with pressure stabilizing cavity, and be arranged on the gas branch pipe that goes out that the pressure stabilizing cavity sidepiece is communicated with pressure stabilizing cavity, it is described that to go out gas branch pipe be four and evenly distribute along the length direction of pressure stabilizing cavity, it is characterized in that, described air intake branch is α with going out gas branch pipe along the angle that the projection on the pressure stabilizing cavity length direction forms along the projection on the pressure stabilizing cavity length direction, and described α is 45 ° to 90 °.
For making that air enters pressure stabilizing cavity smoothly after the supercharging, air intake branch and the angle α that goes out between the gas branch pipe are optimized, air is flowed in the pressure stabilizing cavity along tangent direction, reduce the collision of air in high-speed motion and between the air intake branch, thereby avoid clashing into and the energy loss that produces.The intake manifold of this motor, air enters into pressure stabilizing cavity by air intake branch, and along with the increase of pressure, the air in the pressure stabilizing cavity enters in the cylinder through going out gas branch pipe.
In the intake manifold of above-mentioned motor, described α is 65 ° to 75 °.
In the intake manifold of above-mentioned motor, described four go out gas branch pipe and are connected by circular arc with pressure stabilizing cavity respectively.
When this goes out the gas branch pipe design, four go out between gas branch pipe and the pressure stabilizing cavity all to have adopted bigger circular arc to be connected, the purpose of She Zhiing is like this, these structures are through hydrokinetics calculation, can at utmost reduce to make the air inflow in the pressure stabilizing cavity respectively to go out the gas branch pipe resistance, improve each and gone out the circulation of gas branch pipe.
In the intake manifold of above-mentioned motor, described air intake branch is connected by circular arc with pressure stabilizing cavity.The resistance that can at utmost reduce between pressure stabilizing cavity and the air intake branch is set like this, has improved the circulation between air intake branch and the pressure stabilizing cavity.
In the intake manifold of above-mentioned motor, the sidewall of described pressure stabilizing cavity is provided with pit.Because air pressure has surpassed barometric pressure after the supercharging, the intensity that needs the intake manifold of this motor of consideration, the intake manifold of this motor is when design, pressure stabilizing cavity has adopted five dimple-shaped structural designs, do not influencing under the air circulation condition, increasing the bulk strength and the support of the intake manifold of this motor.
Compared with prior art, the intake manifold of this motor has the following advantages:
1, the design of the intake manifold of this motor, take into full account function and the effect of intake manifold in gas handling system, adopt the air intake branch of optimizing and go out the gas branch pipe angle, reduce the circulating resistance in the air inflow pressure stabilizing cavity, all adopt the fillet of optimizing excessively to be connected between pressure stabilizing cavity and each arm, can improve the circulation that pressure stabilizing cavity enters each arm, improve the uniformity that circulates between each arm.2, in Inlet Manifold Design, the dimple-shaped design is adopted on the pressure stabilizing cavity surface, has improved the intake manifold bulk strength, to satisfy the requirement of engine booster degree.
