Description
Technical field
The utility model relates to a kind of fuel-economizing accelerator with air flow rate adjustment valve of motor car engine, and the torsion while entering acceleration mode with vehicle motor from idling mode is relevant.
Technical background
The supplementary path of the fresh air of automobile current generator is: from air-strainer, through intake manifold, enter in the firing chamber of motor with suitable oil gas mixing ratio.When automobile accelerates from idling mode, driver opens the throttle, and the fuel oil that enters motor is increased.But the air quantity that now enters generator firing chamber from intake manifold but cannot increase moment.Thus, cause oil gas mixing ratio imbalance, fuel consumption increases.
Automobile engine starting moment or speedup moment, motor increased requirement moment of fresh air, but conventional motor car engine air supply system but cannot be accomplished this point.Before this, for having solved above-mentioned this problem in No. M271090th, TaiWan, China patent announcement and the disclosed technology of Chinese model utility 20020120437.X, but still there is the poor and not smooth problem of air inlet of sealing effect, therefore Chinese invention patent 201210488765.5 has proposed a kind of fuel-economizing accelerator, the inwall that is communicated with the through hole of air-strainer is opened in the annular recess on fixed base inwall, on the perisporium of the screw part on diaphragm seat, through hole is communicated with annular recess, such two kinds of radial direction through hole just can be realized unimpeded without aligning, as long as air-strainer is communicated with to annular recess, can not be subject to the restriction of lead to the hole site, the air-strainer of any amount is set, be conducive to increase the amount of fresh air.In automobile engine starting moment or speedup moment, the requirement moment increase of motor to fresh air, now the air pressure in engine exhaust loop changes, cause that the diaphragm in vacuum diaphragm bar moves, taper valve core moves down opens air supply channel, and fresh air, from being connected to the annular recess on the internal face of the air-strainer via through holes fixed base, enters through hole, through taper valve core, entering engine intake manifold again, is the fresh air outside motor supplementary quota.
The threshold value that diaphragm in vacuum diaphragm bar moves is determined by the design parameter of adjusting bolt, spring and diaphragm.For each motor, supplement fresh air, have a definite suitable threshold value.
But, for different engine types, in automobile engine starting moment or speedup moment, the pressure change on engine exhaust loop is different, so the accelerator that need to match for dissimilar engine production, to adjusting the design of bolt, spring and diaphragm, need to make corresponding variation, cause product type various, stock amount is large, and manufacture cost is high, to the requirement of part also corresponding increase, use inconvenient.In addition, find in practice, even if generator of the same type is owing to using abrasion condition different, on generator off-gas circuit, pressure change is also different.And how prior art is when adjusting bolt, spring and diaphragm, very inconvenient, depend on the experience that skilled worker is installed, cause that installation cost raises, installation rate is slow.
