Description
Technical field
The utility model relates to the motor bypass valve, particularly a kind of bypass valve controlling device.
Background technique
At present in automobile supercharged engine application, generally all on pressure-increasing machine air inlet pipeline or gas exhaust piping, adopted bypass valve, crossed supercharging, perhaps when motor does not need supercharging for preventing motor, bypass valve will make pressurized air carry out circulation, so that save fuel oil.Usually bypass valve has two kinds: a kind of is that Electromagnetic Control degree of vacuum is come the indirect operation bypass valve; A kind of is that electronics directly drives bypass valve; The former is applied on the turbosupercharged engine more, the turbo-supercharged engine intake manifold vacuum source is limited, in the time of most of all is between zone of positive pressure, even the instantaneous operating mode of negative pressure is arranged, also can't provide reliable degree of vacuum in real time, must additionally increase a cover vacuum system (as increasing vacuum pump, vacuum tank and respective line), also will increase the different degree of vacuum that a cover solenoid electric valve is regulated bypass valve film chamber; Another kind of electronics directly drives bypass valve, though saved a cover vacuum system, mate with the various operating modes of supercharged engine, and similar own is in the engine air throttle body, and internal structure is very complicated.It is a lot of that these two kinds of bypass valve all can cause the cost of a whole set of bypass valve system to increase.
The model utility content
The utility model technical issues that need to address provide a kind of bypass valve controlling device need not increase the addition of vacuum device to reach, directly gets vacuum near the closure, with mechanically-sapercharged engine self adaption and self-regulating purpose.
For solving the problems of the technologies described above, the technical solution of the utility model is that a kind of bypass valve controlling device comprises mechanical supercharger, throttle body, Air flow meter, air-strainer, intercooler, bypass valve, intake manifold, motor; It is characterized in that: described bypass valve is arranged on the throttle body outlet side, and an end of bypass valve is connected with the inlet end of throttle body outlet side and mechanical supercharger, and the other end is connected with the mechanical supercharger outlet side.
A kind of bypass valve controlling device is characterized in that: described bypass valve comprises vacuum actor, push rod, crank, connecting rod, bypath valve, valve block; Vacuum actor, push rod, crank, the connecting rod formation connecting rod that is linked in sequence, fixing bypath valve on the connecting rod.
A kind of bypass valve controlling device is owing to adopt said structure to have the following advantages: 1, simple in structure, with low cost; 2, good reliability; 3, reduced the supercharged engine fuel consumption rate.

Embodiment
As Figure 1-3: a kind of bypass valve controlling device comprises mechanical supercharger 1, throttle body 2, Air flow meter 3, air-strainer 4, intercooler 5, bypass valve 8, intake manifold 6, motor 7; Bypass valve 8 is arranged on throttle body 2 outlet sides, and an end of bypass valve 8 is connected with the inlet end of throttle body 2 outlet sides and mechanical supercharger 1, and the other end is connected with mechanical supercharger 1 outlet side.Bypass valve 8 comprises vacuum actor 9, push rod 10, crank 11, connecting rod, bypath valve 14, valve block 13; Vacuum actor 9, push rod 10, crank 11, the connecting rod formation connecting rod that is linked in sequence, fixing bypath valve 14 on the connecting rod.Change according to throttle body 2 degree of vacuum, handle bypass valve block aperture by 9 diaphragm pushing drawing rod in the vacuum actor, the stroke of its bypass valve block aperture and push rod 10 is proportional, and the stroke of push rod 10 is determined by the degree of vacuum of vacuum actor 9 fully, the original state of bypass valve 8 is a closed condition, rely on the return spring on the push rod 10 to compress valve block, bypass valve block and valve seat gap are very little, to reduce the pressurized air leakage rate.The major parameter of bypass valve 8 is, bypass valve 8 is opened degree of vacuum 90mmHg, complete opening degree of vacuum 250mmHg, and bypass valve cuts out degree of vacuum 76mmHg fully, the push rod range is between 20.63 ~ 22.70mm.Bypass valve block and valve seat gap are very little, the leakage rate requirement that bypass valve 8 allows, and under the 500mmHg vacuum pressure, the maximum leakage amount of its permission is 50cm
3/ minute.The valve block 13 of this bypass valve 8 uses die casting aluminium material commonly used, and the bypass mouth of pipe is of a size of 34.48mm, guarantees the pressurized air circulation.
As Fig. 4, bypass valve 8 this switching characteristic points and switching characteristic curve are by scrutinizing the parameter that throttle body 2 degree of vacuum and the required pressure ratio of mechanically-sapercharged engine sub load draw, bypass valve 8 effect is the pressure ratio of mechanical supercharger 1 when reducing sub load, thereby reduced the power consumpiton of motor, whether fuel consumption rate reasonable and sub load has direct relation to bypass valve 8 design parameters.
