Description
Technical field
The utility model relates to a kind of fuel-economizing with air flow rate adjustment valve of automobile engine and carriesSpeed device, 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 engine is: from air filter process air inlet discriminationPipe, enters with suitable oil gas mixing ratio in the combustion chamber of engine. When automobile is from idling modeWhen acceleration, driver opens the throttle, and the fuel oil that enters engine is increased. But, now fromThe air capacity that inlet manifold enters engine chamber but cannot increase moment. Thus, cause oilThe imbalance of gas mixing ratio, fuel consumption increases.
Automobile engine starting moment or speedup moment, the requirement of engine to fresh airMoment increases, but conventional automobile engine air supply system but cannot be accomplished this point. Before this,For No. M271090th, TaiWan, China patent announcement and Chinese utility modelIn the disclosed technology of 20020120437.X, solve above-mentioned this problem, but still existed closeEnvelope weak effect and the not smooth problem of air inlet, therefore Chinese invention patent 201210488765.5 proposesA kind of fuel-economizing accelerator, the inwall of through hole that is communicated with air filter is opened at holder inwallOn annular recess in, on the perisporium of the threaded shank 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 filter is communicated withAnnular recess, can not be subject to the restriction of lead to the hole site, and the air filter of any amount is set,Be conducive to increase the amount of fresh air. In automobile engine starting moment or speedup moment, send outMotivation increased the requirement moment of fresh air, and now the air pressure in engine exhaust loop occursChange, cause that the diaphragm in vacuum diaphragm bar moves, taper valve core moves down opens air supply channel,Fresh air is from being connected to the ring-type on the internal face of the air filter via through holes holderGroove, enters through hole, then enters motor intake manifold through taper valve core, for engine supplementsExtra fresh air.
The threshold value that diaphragm in vacuum diaphragm bar moves is by the design of adjusting bolt, spring and diaphragmParameter determines. Supplement fresh air for each engine, have a definite suitable thresholdValue.
But, for different engine types, in automobile engine starting moment or increasingSpeed moment, the air pressure change on engine exhaust loop is different, so need to be for differenceThe accelerator that the engine production of type matches, to adjusting bolt, spring and diaphragmDesign need to be made corresponding variation, causes product type various, and stock amount is large, manufacturing costHeight, to the requirement of part also corresponding increase, uses inconvenient. In addition, find in practice,Even if engine of the same type is owing to using abrasion condition difference, on engine exhaust loop, air pressure becomesIt is also different changing. And how prior art while adjusting bolt, spring and diaphragm, very sideJust, depend on skilled worker's experience is installed, cause that installation cost raises, installation rate is slow.
