Description
Technical field
The utility model relates to a kind of fuel-economizing speed enhancing apparatus of motor car engine, and the torsion when entering acceleration mode with vehicle motor from idling mode is relevant.
Technical background
The additional path of the fresh air of automobile current generator is:, enter with suitable oil gas mixing ratio in the firing chamber of motor through intake manifold from air-strainer.When automobile accelerated from idling mode, the driver opened the throttle, and the fuel oil that enters motor is increased.But but can't moment increase from the air quantity that intake manifold enters the generator firing chamber this moment.Thus, cause the 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 can't be accomplished this point.No. the M271090th, TaiWan, China patent announcement " the little turbine lifter of horsepower " discloses a kind of making-up air device of motor car engine, it mainly is comprised of a vacuum diaphragm bar, a fixed base and an air-strainer, be arranged between motor car engine and engine intake manifold, enter the moment of acceleration mode at generator from idling mode, this lifter can enter engine chamber by one clean air of favorable price increase, increase the inlet of fresh air, improve firing effect.
China model utility 20020120437.X has further increased seal ring on the adjustment bolt of vacuum diaphragm bar, to improve sealing effect; And increased an air filter to increase air inflow on fixed base; In addition, in order to be connected the involutory property of the vent of air filter on the through hole of the screw part of improving the vacuum diaphragm bar and fixed base, increased through hole on described screw part.
But still there is very large defective in the technique effect of above-mentioned measure.
One, sealing effect are still bad.In course of action due to the vacuum diaphragm bar, adjusting bolt need to frequently move up and down, and protrudes between the straight hole section of the seal ring of bolt appearance and the screw of primary diaphragm seat frequently to rub, and the seal ring of colloid weares and teares soon and loses sealing effect.There is no Seal Design between screw outside and protecting cover and be enclosed within, easily come off.
Its two, although increased through hole on the screw part of vacuum diaphragm bar, help to improve the involutory property that is connected the vent of air filter on through hole and the fixed base of screw part of vacuum diaphragm bar, this involutory difficulty that remains.Because the precision of machining is limited, the hole on the parts of two spiral combinations is involutory, and difficulty is very large.Thus, the not smooth problem of air inlet still do not have be improved significantly.
Summary of the invention
The utility model need overcome the poor and not smooth shortcoming of air inlet of prior art sealing effect, and the utility model provides a kind of good sealing effect, accelerated a kind of fuel-economizing accelerator that air flows into.
A kind of fuel-economizing accelerator described in the utility model is characterized in that, comprising:
One vacuum diaphragm bar comprises primary diaphragm seat, the secondary diaphragm seat of involutory sealing, and is clamped in the diaphragm between primary diaphragm seat and secondary diaphragm seat;

The other end of adjusting bolt is limited in spring between itself and diaphragm by pad;
One has the fixed base at two ends, and its center is provided with first through hole that runs through two ends, and an end of through hole and the first screw rod of described secondary diaphragm seat are spirally connected, and the other end connects a pipe joint; Have the vent that several are used for connecting air-strainer on fixed base on the wall of contiguous the second screw rod; Have annular recess on the internal face of described the first through hole, the inner port of described vent is opened in described annular recess, and described the second through hole is communicated with annular recess.
Further, the straight hole section inwall of the screw of described primary diaphragm seat has annular groove, is provided with the seal ring that coordinates with the straight-bar section that adjusts bolt in described annular groove.
Further, around the first through hole, have several through holes that dispels the heat longitudinally on described fixed base.
Further, the end face of described fixed base and secondary diaphragm seat applying is provided with the O RunddichtringO.
Further again, described protecting cover is made by elastic material, is tightened in the outside of the first screw rod of described primary diaphragm seat, and the outside of the first screw rod is provided with hangnail.
Further, have 3 vents that are used for connecting air-strainer on fixed base on the wall of contiguous screw part, to connect 3 air-strainer.
Further, described fixed base is the Hexagon cylinder.
The inwall that the utility model will be communicated with the through hole of air-strainer is opened in annular recess on the fixed base inwall, and on the perisporium of the screw part on the secondary diaphragm seat, through hole is communicated with annular recess, such two kinds of radial direction through hole need not to aim at just can realize unimpeded.Therefore as long as air-strainer is communicated with annular recess, can not be subjected 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.
Automobile engine starting moment or speedup moment, the requirement moment increase of motor to fresh air, this moment, the air pressure of engine air air circuit changed, cause that the diaphragm in the vacuum diaphragm bar moves, taper valve core moves down opens air supply channel, fresh air is from being connected to the annular recess of air-strainer on the internal face of the first through hole on fixed base, enter the first through hole, enter engine intake manifold through taper valve core again, be the outer fresh air of motor supplementary quota, to improve motor moment moment of torsion, save oil consumption, reduce exhaust emissions.
Change on the groove of the inwall that is located at screw for the seal ring of adjusting bolt, seal ring no longer with adjusting the frequent vibration of bolt, reduces wear.Protecting cover coordinates with the first screw rod hangnail outward, and the seal protection of the second layer is provided, and reduces the loss of the degree of vacuum in the vacuum diaphragm bar.
The end face that fixed base and secondary diaphragm seat are fitted is provided with the O RunddichtringO, can solve the loss of vacuum that the fit up gap of secondary diaphragm seat and the second screw rod causes, further improves the sealing effect of vacuum diaphragm bar.
Being provided with vertical radiation hole in fixed base can in time discharge the device internal heat.
The profile of fixed base is made as Hexagon, can when mounted, reduces and roll.
The utility model has the advantage of: good sealing effect, air flow into unimpeded, are conducive to replenishing of a large amount of fresh airs, can promote engine torsion, reduce oil consumption, reduce exhaust emissions.
