Embodiment
See accompanying drawing, the vacuum contant pressure device is made of constant voltage body 5, by-pass cock 3, constant force spring 4.
Constant voltage body 5 is contained on the internal combustion engine inlet, is the carrier and the counterpart of by-pass cock 3, constant force spring 4, and air vent is arranged in it, and leading to Carburetor one end is air inlet road junction 1, leads to cylinder one end and is the road junction 6 of giving vent to anger, and by-pass cock 3 is housed between the two ends.Stationary conduit 2 is arranged in the air inlet road junction 1, and this stationary conduit is corresponding with the moving walkway of by-pass cock 3, forms to regulate passage 2.By-pass cock 3 is similar to the cylindrical body of piston-like, be contained in the constant voltage body 5, its middle part is moving walkway 2 laterally, corresponding with the stationary conduit 2 of constant voltage body 5, this moving walkway 2 is subjected to displacement just can stagger with by-pass cock 3 motions regulates passage 2 change gas-entered passageway sectional areas, by-pass cock 3 tops communicate with atmosphere, accept the atmospheric pressure effect; The bottom communicates with the intake duct of intake valve, accepts the suction pressure effect; The bottom surface connects constant force spring 4, accepts the elastic force effect of constant force spring 4, is the motion of this three's the control adjusting switch 3 of making a concerted effort.The long-pending elastic force with constant force spring 4 of by-pass cock 3 top cross-section determines the control reference pressure of vacuum contant pressure device jointly, the air inlet constant voltage pressure of decision vacuum contant pressure device.
The control power of present embodiment is poor from the atmospheric pressure at suction pressure that acts on by-pass cock 3 bottoms and top, and the control power that this pressure difference produces directly acts on by-pass cock 3, and the size of this control power changes with the variation of suction pressure.The full admission pressure decision that the control reference pressure of present embodiment is allowed by fuel antiknock ability realizes by changing by-pass cock 3 top cross-section elastic force long-pending and change constant force spring 4.When motor was static, because the elastic force effect of constant force spring 4 makes by-pass cock 3 be positioned at upper dead center position, the moving walkway of by-pass cock 3 and the stationary conduit of constant voltage body 5 staggered at this moment, regulated passage 2 and closed; During engine start, because the air-breathing effect of air inlet, make intake duct produce degree of vacuum, by-pass cock 3 bottoms produce degree of vacuum, barometric pressure is to the long-pending pressure that produces of by-pass cock 3 top cross-section, when the pressure that barometric pressure is produced when the degree of vacuum of intake duct to by-pass cock 3 surpasses the elastic force of constant force spring 4, by-pass cock 3 moves downward, open regulating passage 2, by-pass cock 3 moves downward and reaches lower dead centre, after the adjusting passage was opened fully, by the closure control of Carburetor, this moment, inflammable mixture flowed on intake duct just as there not being the vacuum contant pressure device intake vacuum (representative cylinder intake air quantity) fully; When excessive the or overweight rotating speed of engine load is too low when throttle opening, cylinder intake air quantity increases, the cylinder compressive force reaches the maximum value that fuel antiknock ability allows, at this moment, intake vacuum is reduced to the suction pressure difference that makes the atmospheric pressure that acts on by-pass cock 3 tops and bottom and produces the elastic force that the active force of by-pass cock 3 is lower than constant force spring 4, by-pass cock 3 possesses moving condition, constant force spring 4 promotes by-pass cock 3 and moves upward, close minor adjustment passage 2, stop cylinder intake air quantity further to strengthen, constant cylinder maximum compression guarantees that the cylinder maximum compression is no more than the maximum value that inflammable mixture antiknock ability allows.Make low ron fuel (90
#Gasoline) can in the firing chamber of high compression ratio (13: 1), normal combustion not produce phenomenon of detonation; When little or engine load alleviates rotating speed and raises when throttle switch, regulate passage and open fully again.(operating mode commonly used of motor car engine is at the low-load place because completely negative operating mode motor car engine is seldom used, sedan car motor particularly), so, when this degree of vacuum manostat is used on the motor car engine, 3 percent 90 times of by-pass cock all are in the state of rest of lower dead centre, only by-pass cock 3 just moves and closes minor adjustment passage 2 when automobile quickens suddenly or goes up a slope, and just cylinder intake air quantity is started to control to make and uses.
As seen above-mentioned, by-pass cock 3 moves downward to be opened the condition of regulating passage 2 and be: intake vacuum makes suction pressure and atmospheric pressure act on pressure difference on the by-pass cock 3 to the active force of the by-pass cock generation elastic force greater than constant force spring 4, by-pass cock 3 just moves downward compression constant force spring 4, open and regulate passage 2, simultaneously in the process of compression constant force spring 4, the energy storage that acts on the pressure difference generation on the by-pass cock 3 in the elastic force of constant force spring 4.By-pass cock 3 moves downward the condition of closing minor adjustment passage 2: intake vacuum make suction pressure and atmospheric pressure in the pressure difference of by-pass cock 3 to the active force of by-pass cock 3 generations elastic force less than constant force spring 4, constant force spring 4 discharges the power capacity that stores and promotes by-pass cock 3 motions, change the gas-entered passageway sectional area, the performance control action, the purpose that reaches automatic control cylinder full admission amount repeatedly like this.By-pass cock 3 has generation power, detects the function of suction pressure, control cylinder air inflow.The elastic force size of constant force spring 4 and the control reference pressure size of the long-pending common decision manostat of by-pass cock 3 top cross-section, thus determined different octane fuel to adapt to the motor of different compression ratios.
