Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As depicted in figs. 1 and 2, specifically including according to the engine aspirating system of the utility model embodiment：
Inlet manifold 1, electronic actuators 2, inlet manifold 3 and changeover valve 4, wherein, with different multiple of length in inlet manifold 3
Manifold passage, multiple independent manifold passages control changeover valve 4 to be used to cut off with connecting inlet manifold by electronic actuators 2
1, the angle that changeover valve 4 rotates can control the circulation area of inlet manifold, and inlet manifold inlet channel can be controlled by reaching
Quantity, inlet flow sectional area.ECU controllers in the operating condition according to engine operation condition and to inlet manifold length,
The demand of circulation area, control sub- actuator 2 to control the position of changeover valve 4, reach engine performance and inlet manifold length,
The best match of circulation area, better meet to the demand of air inlet under different working conditions, and then lift the performance of engine
With economy.
Specifically, inlet manifold 1 is used to engine charge importing inlet manifold 3.Electronic actuators 2 are arranged on this and entered
On gas house steward 1, and control and connect with ECU, ECU controllers are according to engine operation condition and to inlet manifold length, circulating face
Long-pending demand, control electronic actuators 2 control the position of changeover valve 4.
Manifold passage with the different multiple independent parallels of length in inlet manifold 3, the manifold passage and inlet manifold 1
Connection, engine charge is imported wherein.Preferably, first with two different independent parallels of length in inlet manifold 3
The manifold passage 32 of manifold passage 31 and second.I.e. inlet manifold uses binary channels admission manifold branch structure, the length of two manifold passages
Degree is different.
Changeover valve 4 is arranged on multiple manifold passages in inlet manifold 3 and the company of inlet manifold 1 by clamp nut 5
Logical place, and control and connect with electronic actuators 2.ECU controllers are according to engine operation condition and to inlet manifold length, circulation
The demand of area, control electronic actuators 2 control the position of changeover valve 4, and the angle of rotation can control the stream of inlet manifold
Logical area, inlet manifold inlet channel quantity, inlet flow sectional area can be controlled by reaching.The control rotation of Electronic Control actuator
Valve can arbitrarily control aperture, switch in control gas handling system between two kinds of different manifolds, it is stepless to realize that circulation area is realized
