In car load running process, motor needs different rotating speeds to deal with different road conditions, and the output of different rotating speeds needs intake manifold that different air inflows is provided, when the slow-speed of revolution is turned round, moment of torsion in the time of need to improving the motor slow-speed of revolution, makes car load stronger when starting and climbing; When high rotation speed operation, need to improve the air inflow under the high rotating speed of motor, thus the power while improving the high rotating speed of motor.In prior art, mostly the airflow pattern that is installed on the intake manifold of motor is inconvenient, can not be suitable for the requirement under different engine operating mode.
Therefore, need to improve the intake manifold of motor, make its internal gas flow form can meet different driving cycles, when the slow-speed of revolution air inlet steady, thereby the moment of torsion while improving the motor slow-speed of revolution makes car load stronger when starting and climbing; When high rotating speed, air inflow strengthens, thereby the power while improving the motor slow-speed of revolution makes car load can reach the fastest speed in steady section.
Model utility content
In view of this, the utility model provides a kind of variable-length intake manifold, and its internal gas flow form can meet different driving cycles, when the slow-speed of revolution air inlet steady, thereby the moment of torsion while improving the motor slow-speed of revolution makes car load stronger when starting and climbing; When high rotating speed, air inflow strengthens, thereby the power while improving the motor slow-speed of revolution makes car load can reach the fastest speed in steady section.
Variable-length intake manifold of the present utility model, comprise the buffering pressure stabilizing cavity setting gradually by airintake direction and be connected and medium is sent into being in charge of of cylinder with described buffering pressure stabilizing cavity, described buffering pressure stabilizing cavity comprises long air flue and loses heart, and is provided with the adjusting turnover panel for switching described long air flue and losing heart in described buffering pressure stabilizing cavity.
Further, described in lose heart trace overlap in described long air flue and form the part of described long air flue, described adjusting turnover panel be arranged at described long air flue with described in intersection the nearly described buffering pressure stabilizing cavity inlet end of the suction port of losing heart.
Further, described in, be in charge of and comprise the straight length being connected with buffering pressure stabilizing cavity and the smooth curve pipeline section being connected with cylinder intake duct.
Further, the cross section of described smooth curve pipeline section fades to pancake along airintake direction by circle.
Further, the profile cross-section of losing heart described in area reduces gradually along airintake direction.
Further, described short airway length is 640 ± 10mm.
Further, described long airway length is 1280 ± 10mm.
