Description
Technical field
The present invention relates to a kind of novel fuel-economizing accelerator with air flow rate adjustment valve of motor car engine, 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.Before this, for having solved above-mentioned this problem in TaiWan, China patent announcement M271090 number 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 the fixed base inwall, through hole is communicated with annular recess on the perisporium of the screw part on the diaphragm seat, such two kinds of radial direction through hole need not aligning and just can realize unimpeded, as long as air-strainer is communicated with annular recess, then can not be subjected to the restriction of lead to the hole site, the air-strainer of any amount is set, is conducive to increase the amount of fresh air.In automobile engine starting moment or speedup moment, motor is to the requirement moment increase of fresh air, this moment, the air pressure in engine exhaust loop changed, cause that the diaphragm in the vacuum diaphragm bar moves, taper valve core moves down opens air supply channel, and the annular recess of fresh air from the internal face that is connected to the air-strainer via through holes on the fixed base enters through hole, enter engine intake manifold through taper valve core again, be the outer fresh air of motor supplementary quota.
The threshold value that diaphragm in the vacuum diaphragm bar moves is determined by the design parameter of adjusting bolt, spring and diaphragm.Replenish fresh air for each motor, a definite suitable threshold value is arranged.
But, for different engine types, in automobile engine starting moment or speedup moment, the pressure change on the engine exhaust loop is different, so the accelerator that need to match for dissimilar engine production, namely need to make corresponding variation to the design of adjusting bolt, spring and diaphragm, cause product type various, the stock amount is large, and manufacture cost is high, to the also corresponding increase of requirement of part, use inconvenient.In addition, find in practice, even if generator of the same type is owing to using abrasion condition different, pressure change also is different on the generator off-gas circuit.And prior art is very inconvenient when adjusting bolt, spring and diaphragm how, depends on the experience that the skilled worker is installed, and causes that installation cost raises, installation rate is slow.
