Abstract
The utility model relates to a novel-structure four-air-channel plastic intake manifold. The intake manifold comprises a pressure stabilization cavity and air channels. One end of the pressure stabilization cavity is communicated with an air inlet, and the other end of the pressure stabilization cavity is communicated with the four air channels with the same length. The air inlet is located on upper portions of the air channels, the pressure stabilization cavity is located on lower portions of the air channels, a front boss of the air inlet is provided with an air inlet temperature pressure sensor installation opening, the side face of the pressure stabilization cavity is provided with an exhaust gas recirculation inlet, the air inlet temperature pressure sensor installation opening and the exhaust gas recirculation inlet are respectively communicated with the pressure stabilization cavity, and a support is arranged on the upper portion of one of the air channels. The intake manifold is simple in structure and reasonable in design, manufacture difficulty and cost are reduced, spaces on the upper portion of the intake manifold and spaces around the intake manifold are effectively made use of, parts on the periphery of the intake manifold are reasonably arranged, the air inlet temperature pressure sensor installation opening and the exhaust gas recirculation inlet are reasonably arranged, uniformity of air inflow is benefited, volumetric efficiency is improved, engine performance can be improved, assembly is convenient, and the engine weight is reduced due to the fact that plastic is lighter than aluminum alloy.
Description
Technical field
The utility model relates to a kind of intake manifold, particularly relates to a kind of new structure four air flue plastic air intake manifolds that are used on the automotive gasoline engine.
Background technique
At present, existing four airway induction manifold materials are aluminum alloy, are arranged as the horizontal air inlet in front or side usually, and structure is compact.The deficiency of this structure is that intake manifold part positive and side arrangement is more, the assembly space anxiety, intake manifold front or side also need bigger space throttle body and associated pipe are set, if and arrange unreasonable, influence the trend and the charging efficiency of air flue, and then influence engine performance.In addition, the upper space for intake manifold does not then utilize.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provide a kind of simple in structure, reasonable in design, can effectively utilize intake manifold top and peripheral space, realize the new structure four air flue plastic air intake manifolds of intake manifold periphery component reasonable Arrangement.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise pressure stabilizing cavity, air flue, described pressure stabilizing cavity one end is communicated with suction port, the air flue that the other end is identical with four length communicates, described suction port is positioned at air flue top, pressure stabilizing cavity is positioned at the bottom of air flue, suction port front side boss is provided with air inlet temperature and pressure sensor mount inlet, the pressure stabilizing cavity side is provided with EGR port, air inlet temperature and pressure sensor mount inlet, EGR port are communicated with pressure stabilizing cavity respectively, and described air flue top also is provided with support.
The utility model has the advantages that:
1. simple in structure, reasonable in design, reduced manufacture difficulty and cost;
2. effectively utilize intake manifold top and peripheral space, reasonable Arrangement intake manifold periphery component;
3. air inlet temperature and pressure sensor, EGR port connection and reasonable arrangement, it is even to be beneficial to air inlet, improves charging efficiency, can improve engine performance, and is convenient to assembling;
4. the relative aluminum alloy of plastics is in light weight, has reduced engine weight.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model comprises pressure stabilizing cavity 2, air flue 3, described pressure stabilizing cavity 2 one ends are communicated with suction port 1, the air flue 3 that the other end is identical with four length communicates, described suction port 1 is positioned at air flue 3 tops, pressure stabilizing cavity 2 is positioned at the bottom of air flue 3, suction port 1 front side boss is provided with air inlet temperature and pressure sensor mount inlet 5, pressure stabilizing cavity 2 sides are provided with EGR port 6, air inlet temperature and pressure sensor mount inlet 5, EGR port 6 are communicated with pressure stabilizing cavity 2 respectively, and described air flue 3 tops also are provided with support 4.
Described support 4 is arranged on second branch airway 7.
Described pressure stabilizing cavity 2, air flue 3, suction port 1, air inlet temperature and pressure sensor mount inlet 5, EGR port 6 all adopt plastics.
The utility model is by the plastic air intake manifold of design a kind of upper end air inlet, make full use of the intake manifold superjacent air space, for the layout of air flue and side component is abdicated enough spaces, reach and optimize intake manifold air flue and side component layout, reduce the purpose of oil consumption, raising engine performance.
Air flue of the present utility model and pressure stabilizing cavity connection and reasonable arrangement, air inlet is even, the charging efficiency height, engine power performance is good, and has alleviated engine weight, has reduced vehicle oil consumption.
