Hereinafter, with reference to Fig. 8 (a), Fig. 8 (b) and Fig. 9, the inlet manifold stable-pressure device 100 utilizing the present invention is carried out voltage stabilizing
The principle of action illustrates.
Fig. 8 (a), Fig. 8 (b) are to the schematic diagram needing the necessity carrying out ratchet opening and closing to illustrate.Fig. 9 is to represent profit
Inlet manifold stable-pressure device 100 by the present invention carries out the schematic diagram of voltage stabilizing action.
In Fig. 8 (a), thus it is shown that the gas handling system of general electromotor.Due to the opening and closing of engine valve, respectively entering
The sine-shaped pressure oscillation being similar in Fig. 8 (b) can be formed in gas manifold, and owing to each cylinder gate is according to specific time sequence
Carrying out opening and closing, therefore, the sine pressure wave in each inlet manifold also has corresponding phase offset.
Thus, in the present invention, utilize inlet manifold stable-pressure device, control corresponding ratchet, only to make in particular moment
Inlet manifold connects with the inlet manifold of specific cylinder, and makes inlet manifold not connect with the inlet manifold of other cylinder, thus
Can eliminate owing to pressure oscillation produces pressure influence to inlet manifold stable-pressure device internal (voltage stabilizing chamber 150), reach stable
The effect of cavity indoor pressure.
It addition, as it is shown in figure 9, owing to the second air induction conduit mouth ICP2 is connected with inlet manifold CM, therefore, it is possible to keep pressure
Power P0Consistent with inlet manifold's pressure.
Owing to difference is designed in the path of each inlet manifold, therefore, the pressure of each inlet manifold also differs.Assume each air inlet
The pressure of manifold is respectively P1、P2、P3、P4, and suppose P4＞ P3＞ P2＞ P1。
According to flowing freely air capacity equation:
Wherein, qv1 qv2For volume of air flow；
p1 p2For gas pressure；
T1 T2For gas temperature.
Therefore, the volume flowing into each manifold in inlet manifold stable-pressure device 100 is
That is, qv4＜ qv3＜ qv2＜ qv1。
It follows that by the structure of the inlet manifold stable-pressure device of the present invention, it is possible to the volume to each air inlet discrimination trachea
There is fine setting effect.Originally supplementing less gas in the manifold that flow is big, the manifold that flow is little originally supplements more gas.Meanwhile,
By the opening and closing in the hole of sequential control ratchet, separate do not have just at the cylinder of air inlet to just in the pressure influence of cylinder of air inlet.
