Problems solved by technology

[0003] The object of the present invention is: to solve the above problems, a variable intake manifold is proposed, the volume of the pressure stabilizing chamber and the length of the air passage of the intake manifold can be changed simultaneously, which solves the problem that the volume of the stabilizing chamber is not variable. The volume of the plenum chamber and the length of the air passage meet the different intake requirements of the engine at high and low speeds

Embodiment Construction

[0012] figure 1 and figure 2 A specific embodiment of the variable intake manifold of the present invention is shown, which includes a plenum chamber 3 and an air passage 1, and the intake end of the air passage 1 communicates with the plenum chamber. On the air passage 1, near the inlet end of the air passage, there is a regulating chamber 4 communicated with the air passage, and at the junction of the regulating chamber 4 and the air passage 1, a device for controlling the regulating chamber 4 is installed. The opening and closing of the valve plate 2 (the valve plate can realize the rotation of 90 degrees).

[0013] The working principle of this embodiment is as follows:

[0014] like figure 1 As shown, when the engine is running at a low speed, the valve plate 2 is in the closed position and the adjustment chamber 4 is closed (that is, the adjustment chamber is separated from the air passage), and the length of the air passage 1 at this time is longer (such as figure ...

Abstract

The invention discloses a variable intake manifold, which comprises a pressure-stabilizing chamber and an air passage through which the intake end communicates with the pressure-stabilizing chamber. An adjusting chamber communicating with the air passage is also arranged on the air passage, and A valve plate for controlling the opening and closing of the regulating chamber is arranged at the junction of the regulating chamber and the air passage. The volume of the plenum chamber and the length of the air passage of the intake manifold can be changed at the same time, which solves the problem that the volume of the plenum chamber cannot be changed. different needs.

Description

technical field [0001] The invention relates to a variable intake manifold for use in an internal combustion engine. Background technique [0002] The current variable intake manifolds for internal combustion engines are all variable in the length of the air passage and the cross-sectional area of ​​the air passage, without changing the volume of the plenum chamber. The ideal working state of the engine (internal combustion engine) air intake is that the volume of the plenum chamber can change with the operating conditions of the engine, but it is currently difficult to achieve in hardware. Therefore, the current volume of the plenum chamber is a constant value. The volume of the plenum chamber affects the air supply of the engine, which in turn affects the performance of the engine. Therefore, the plenum chamber is not variable so that the engine does not have ideal air supply under different working conditions. Contents of the invention [0003] The object of the pres...
