Abstract
The utility model relates to an engine air intake manifold. Main air paths are bended and folded and are arranged symmetrically on the two sides of a stable pressure cavity. Every air path is divided into two at the joint with an air outlet of a head by a separating rib. A slid plate is arranged in the air outlet. A controller is composed of a slid plate, an inner rocker, an outside rocker and an executor. The controller is arranged on the body of the intake manifold. The utility model can be arranged in a relatively small space and meet the air demand of the engine as the air paths are bended and folded and then contributed symmetrically. The controlling mechanism arranged on the air paths works to open and close a certain number of air paths to produce an eddy so as to adjust air intake. The utility model can control the direction and the flow rate of the air intake thus realizing the target of increasing engine performance and reducing discharge.
Description
Technical field
The utility model relates to a kind of engine intake manifold, especially relates to a kind of petrolic intake manifold, particularly engine emission and arrangement space is had the intake manifold of requirement.
Background technique
Engine intake manifold effect itself is exactly a device that fresh air is sent to each cylinder body of motor, cooperates the superincumbent oil sprayer of installation to provide inflammable mixture for motor.The intake manifold of different air flue trends takes up space and varies in size, and its motor charging efficiency that causes also can be different simultaneously.
At present, common intake manifold structural form is various, general arranged side by side being connected on the pressure stabilizing cavity of the air flue of intake manifold, and the inlet flange opening on the pressure stabilizing cavity is positioned at the one-sided of all air flues, but has deficiencys such as smoothness, spatial arrangement are unreasonable.
Simultaneously, the engine intake manifold of the variable air inlet flow direction and flow is also rare.
Summary of the invention
In order to overcome the deficiency that existing engine intake manifold exists, the purpose of this utility model is to provide a kind of engine intake manifold, this engine intake manifold is not only under intake manifold spatial arrangement condition of limited, can guarantee the needed tolerance of motor, and rational in infrastructure, charge air flow is smooth and easy.
The further purpose of the utility model provide a kind of change inlet stream to the engine intake manifold of flow.Thereby the burning of control motor improves the purpose that engine performance and realization reduce exhaust emissions.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of engine intake manifold, be made of first air flue, second air flue, the 3rd air flue, the 4th air flue and the pressure stabilizing cavity that is connected thereof, its feature exists: first air flue and the mutual intercross arrangement of second air flue; The mutual intercross arrangement of the 3rd air flue and the 4th air flue.The air inlet inlet is set on the pressure stabilizing cavity and is positioned at its center.Overlook on the direction homonymy air flue and intersect crooked overlappingly, air flue curves inwardly downwards on the side-looking direction, all is connected on the pressure stabilizing cavity then.The air flue of intake manifold is connected on the long pressure stabilizing cavity side by side relatively at present, and space availability ratio is relatively good.Be connected on the air outlet of cylinder cap, each air flue separates muscle separately by one, thereby reaches the purpose that each air flue is divided into two.
A kind of change inlet stream to the engine intake manifold of flow, overall structure is divided into the intake manifold main body and the control mechanism two large divisions forms.Slidably slide plate is set in the air outlet of intake manifold, the air outlet is arranged on the slide plate.Control mechanism is made up of slide plate, inner rocker arm, outer rocker arm and final controlling element, control mechanism all is installed to above the intake manifold main body, slide plate, inner rocker arm, outer rocker arm and final controlling element connect in proper order, realize the purpose that the intake manifold throughput changes by the Collaboration between them.The working principle of control mechanism: when motor sends the final controlling element that control mechanism is given in instruction according to actual needs the time, so the flexible rod of final controlling element produces action, owing to connecting in proper order, final controlling element flexible rod, outer rocker arm, inner rocker arm and slide plate produce interlock, thereby make slide plate Sliding Control air flue air outlet size in the air outlet, realize the purpose that the intake manifold throughput changes.
Good effect of the present utility model: owing to adopt the air flue of intake manifold main body to adopt the symmetric design principle, the air flue symmetric configuration is in the pressure stabilizing cavity both sides, upward opening air inlet from pressure stabilizing cavity, deliver air to the intake duct of cylinder cap then by the air inlet air flue of bending stack, guarantee the air inflow of its air inlet smoothness and engine demand under limited arrangement space.The air outlet side of this external intake manifold, air flue is by being divided into two, control mechanism opens and closes the size that intake manifold part air flue produces eddy current and changes air inflow on the intake manifold by being installed in, the air flue trend that cooperates cylinder cap, final realization control enters the airflow direction of engine chamber and the burning that throughput is controlled motor, thereby improves the performance of motor and reduce the purpose of discharging.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
