Abstract
The utility model discloses an intake manifold for the automobile engine, which comprises a front air path 1, a back air path 2, a voltage-stabilizing cavity 3, a nozzle 4, a flange face 5 arranged on the cylinder lid, a waterway 6 and a thermostat mount 7. The middle section of the front air path 1 is a transition to the arc, and the shape of the waterway 6 is straight. The utility model can smooth the whole flow field of the front air path so that the air flow is smooth and the phenomena of the convolution is eliminated. Meanwhile, the convergence of the cross-sectional area of the waterway turns consistent, the flow in the water channel is smooth and the phenomena of the choke is eliminated. Thus, the overall performance of the automobile is greatly enhanced.
Description
One, technical field
The utility model relates to a kind of gas handling system of motor car engine, specifically relates to a kind of intake manifold of motor car engine.
Two, background technique
Existing motor car engine is straight transitions (as shown in Figure 3) with the intermediate section of the preceding air flue of intake manifold, has corner angle, so that air-flow has some setbacks, causes " circling round " phenomenon; The water channel shape of intake manifold is slightly crooked, and promptly the cross-section area of water channel differs in size (as shown in Figure 4), is easy to generate air when adding cooling liquid, causes " feeling suffocated " phenomenon.Thereby directly influenced the performance of motor car engine.
Three, model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and the intake manifold of the unimpeded motor car engine of the current of a kind of airflow smooth that can make air flue, water channel is provided.
The purpose of this utility model realizes by following technical solution: a kind of intake manifold of motor car engine, comprise preceding air flue, back air flue, pressure stabilizing cavity, nozzle, cylinder cap mounting flange face, water channel, thermostat fitting seat, the intermediate section of air flue is an arc transition before described, and described water channel be shaped as straight way.
After adopting the utility model structure, because the intermediate section of preceding air flue is an arc transition, and to be tending towards circle suitable in the whole flow field of air flue before making, and reaches airflow smooth, eliminated " circling round " phenomenon, makes that gaseous combustion is more abundant, oil consumption is lower, the discharging is more reasonable; Owing to the straight way that is shaped as of water channel, and its cross-section area is reached unanimity, kept the current of water channel unimpeded, eliminated " feeling suffocated " phenomenon.Therefore, the overall performance of motor car engine has obtained significantly improving.
Four, description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Fig. 1 is the structural representation of the intake manifold of the utility model motor car engine.
Fig. 2 is the rear view of Fig. 1.
Fig. 3 is the structural representation of the intake manifold of known motor car engine.
Fig. 4 is the rear view of Fig. 3.
Five, embodiment
With reference to Fig. 1, Fig. 2 as can be known, the intake manifold of the utility model motor car engine, air flue 1, back air flue 2, pressure stabilizing cavity 3, nozzle 4, cylinder cap mounting flange face 5, water channel 6, thermostat fitting seat 7 before comprising, the intermediate section of air flue 1 is an arc transition before described, and described water channel 6 be shaped as straight way.In order to solve the problem of the installation inconvenience between intake manifold and the cylinder head, can make the shape of the rear side oral area 8 of water channel 6 into plane, and link to each other, to reserve bigger spanner space (position shown in A among Fig. 2) with cylinder cap mounting flange face 5.Thereby the workman easily and fast, installs beat, reduces working strength of workers with quickening when intake manifold and cylinder head are installed.
The structural representation of the known air intake manifold of automotive engine that Fig. 3 and Fig. 4 are mentioned for aforesaid background technique part.Wherein the intermediate section of preceding air flue is a straight transitions as can be seen from Figure 3, has corner angle; The shape of water channel slightly crooked (cross-section area that is water channel differs in size) as can be seen from Figure 4, and it is smaller that required spanner space is installed.
Claims (2)
1, a kind of intake manifold of motor car engine, comprise preceding air flue (1), back air flue (2), pressure stabilizing cavity (3), nozzle (4), cylinder cap mounting flange face (5), water channel (6), thermostat fitting seat (7), it is characterized in that: the intermediate section of air flue (1) is an arc transition before described, and described water channel (6) be shaped as straight way.
2, the intake manifold of motor car engine as claimed in claim 1 is characterized in that: the rear side oral area (8) of described water channel (6) be shaped as the plane, and link to each other, to reserve bigger spanner space with cylinder cap mounting flange face (5).
