一种发动机的可变进气歧管制造技术

本发明专利技术公开了一种发动机的可变进气歧管，该进气歧管为螺旋状，设有进气端和出气端；在所述进气歧管内的气道内设置有长气道和短气道，在长气道和短气道的进气口的交界处设有旋转阀片。当旋转阀片旋转到所述短气道的进气口位置，短气道关闭，长气道开启，形成具有长的气道的进气歧管；当旋转阀片旋转到所述长气道的进气口位置，短气道开启，长气道关闭，形成具有短的气道的进气歧管。采用此技术方案，通过设置旋转阀片进行长气道和短气道的切换，实现发动机进气歧管的气道长度可变，以满足发动机在各种工况下对充气效率的要求，提高发动机的整体工作性能；另外，旋转阀片本体为圆弧状，便于对气道内气流的引导。

Variable intake manifold for an engine

The invention discloses a variable intake manifold of the engine, the intake manifold is spiral, is provided with a gas inlet and gas outlet; the intake manifold of the airway is arranged in the long and short of airway airway, a rotary valve plate at the junction of long and short air inlet airway. When the inlet position of the rotary valve plate to rotate to the short airway, shortness of breath road closed, long open airway, the formation of intake manifold has a long passage; when the inlet position of the rotary valve plate to rotate to the length of the airway, airway open short, long airway closure, form intake manifold with short of gas. By adopting the technical scheme, switch long and short of the airway airway by setting rotating valve, variable length intake manifold airway, to meet the engine under various working conditions on charging efficiency requirements, improve the overall performance of the engine; in addition, the rotary valve sheet body is arc-shaped, easy to airway airflow guide.
