The embodiment of description is made various changes and modifications without departing from the scope of the utility model and spirit.In addition, in order to clear and
Succinctly, the description to known function and construction is eliminated.
Reference picture 1 and Fig. 3, in order to solve the above technical problems, the engine charge regulation that the utility model embodiment provides
System, including：
Inlet manifold 1；
Cylinder head 2, the cylinder head 2 are provided with the first through hole relative with the inlet manifold 1；
Variable flow component 3, it is arranged between the inlet manifold 1 and the cylinder head 2, is set on the variable flow component 3
There is second through hole 31 relative with the first through hole；
Turnover panel 4, it is rotatablely arranged in second through hole 31, the turnover panel 4 includes and second through hole 31
Center line is in the first state of preset first angle, and with the center line of second through hole 31 in preset second angle the
Two-state, the first angle are 0 degree, and second angle is an angle for being more than 0.
When engine, which is in, to run at high speed, turnover panel 4 is in first state.Under this state, turnover panel 4 divides the second through hole 31
Two passages, the area of section of upper and lower two passages and of substantially equal with the area of section of the second through hole up and down are cut into, now, is entered
Gas in gas manifold 1 enters to engine air cylinder interior by upper and lower two passages, and turnover panel 4 will not be in inlet manifold 1
The flowing of gas have an impact, it is thus possible to meet big air inflow required during high engine speeds operating.
When engine is in low-speed running, turnover panel 4 is in the second state, now, the side wall of the through hole 31 of turnover panel 4 and second
Between form the less air stream transportation passage in an aperture, also, the area of section of the air stream transportation passage is less than the second through hole 31
Area of section, the gas in inlet manifold 1 flows into engine air cylinder interior by the air stream transportation passage.
When turnover panel 4 is in the second state, because turnover panel 4 stops the part of the second through hole 31, the air stream transportation of formation
The sectional area of passage is significantly smaller than the area of section that turnover panel 4 is in two passages formed under first state in the second through hole 31
Sum.When flowing in the second through hole 31, flow direction is sent and changed due to the stop of turnover panel 4 gas in inlet manifold 1
Become so that larger Tumble and swirl can be formed by the gas of the air stream transportation passage, so as to cause in the presence of big tumble flow
