IAC: nws yog dab tsi, cov ntsiab tsis ua hauj lwm, hauv paus ntsiab lus

Qhov tsab xov xwm yuav muab suav hais tias los ntawm lub IAC, nws yog dab tsi, cov ntsiab cai ntawm lub lag luam, qhov yooj yim chaw. Tseem yuav tsum tau hais txog thaum yuav tsum tau mus hloov lub kaw ceev regulator Vaz tsheb. Koj paub hais tias cov niaj hnub tsheb yog packed nrog ib tug ntau yam ntawm sensors thiab actuators. Cov muaj xws li cov kev tswj ntawm idling. Nrog nws txhawb lub cav ceev. Thaum koj ua txhaum lub IAC lub cev muaj zog pib ua tsis zoo, muaj cov tsos mob xws li tsis ruaj tsis khov kev sib hloov ntawm lub crankshaft, nws puv lossi dhia. Nyob rau hauv tej rooj plaub, nws yog tau hais tias lub cav tsis thiab yuav tsis pib.

Yuav ua li cas yog lub IAC?

Ua ntej, peb xav txog qhov sab nraud thiab sab hauv cov tsos ntawm cov IAC. Yuav ua li cas yog nws, koj yuav kawm tau los ntawm qhov tsab xov xwm. Nws yog ntsia nyob ze ntawm lub throttle, nrog nws ua kom muaj lub cav ceev ntawm ib theem ntawm 700 rau 900 revolutions ib feeb. Qhov no yog accomplished los kho cov huab cua mov mus rau lub throttle ntaus ntawv. Externally idling xws zoo li ib tug me me yas thawv, hauv uas yog me me stepping motors (los yog solenoid). Tab sis ib co qauv muaj ib tug cylindrical zoo, ua los ntawm cov hlau. Lub Stepper lub cev muaj zog los yog solenoid actuates ib tug pas nrig ntawm hlau, uas yuav qhib thiab kaw lub cua txaus.

Khiav lub cav ntawm kaw

lub cev muaj zog ua tau hauj lwm ntawm heev tsawg revs - qhov no yog ib tug heev hnyav luag hauj lwm rau nws. Yuav tsum pib nrog, cov roj ntawm cov huab cua heev maj mam noj mus rau hauv lub combustion chamber, yog li txoj kev ua ib sib tov hais ineffectively. Nws yuav tsum raug sau tseg hais tias ib tug heev me me siab nyob rau hauv lub engine kom tsawg manifold, nws yog yog li ntawd tau ingress ntawm rav cua tsheb gases rov qab mus rau hauv lub combustion chamber. Nws muaj peev xwm yuav xaus lus tias efficiency yuav txo tau tshwm sim, ib qho kev nce nyob rau hauv tso emissions, ntau coj ntsiab ntawm lub tog raj kheej-piston pab pawg neeg. Nws yog ib nqi sau cia hais tias tus ntaus ntawv yog tsis nqi heev. IAC tau raug nqi txog 400-500 rubles.

Kaw ceev kev cai

Yog hais tias peb nco qab carbureted xyaw, lub cav ceev ntawm idling tswj los ntawm txoj kev tshwj xeeb screws. Nyob rau hauv tus txheej txheem ntawm qhov chaw kawm yog tsim nyog los saib xyuas cov pa ntsiab lus ntawm lub tso gases, lub crankshaft ceev. Tus txheej txheem nws tus kheej yog heev lub sij hawm-siv thiab yuav tsum tau tsim nyog cov neeg mus nqa nws tawm. Thaum tus thawj yuam roj txhaj system, tus txheej txheem yog ho yooj yim zog.

Nyob rau hauv qhov tseeb, lub IAC, yog dab tsi nws yog los sib tham nyob rau hauv tsab xov xwm, yog tus Actuator, es lub sensor. Nws yog txuas mus rau ib tug hluav taws xob tswj tsev, uas sau tag nrho cov ntaub ntawv nyob rau hauv lub cev muaj zog nyob rau hauv lub sij hawm. Raws li cov ntaub ntawv, lub computer generates ib lub tsheb tswj tag nrho cov tseem ceeb tsis muaj tus nrog combustion engine. Nws yuav tsum tau muab sau tseg tias tus tsim ntawm lub idling regulator yog tseem cia nrog, txij li thaum diesel xyaw siv ib tug txawv kiag li tswvyim haum.

Yuav ua li cas puas muaj tus IAC

Yog li, lub saum toj no los sib tham, uas hu rau lub regulator ntawm idling. Txhua yam uas tau piav yuav pom tau hais xwb yog hais tias tus idling ua cua txaus, bypassing lub throttle valve. Qhov no tshwm sim los ntawm txoj kev lub bypass channel. Nyob ntawm seb yuav ua li cas lub channel yog qhib, cov huab cua mov txawv. Nco ntsoov tias tus txhaum regulator idling teeb «check engine» tsis teeb nyob rau hauv feem ntau. Thiab nco ntsoov hais tias tus regulator - nws tsis yog lub sensor. IAC - qhov no Actuator, txij li thaum nws tsis ntsuas.

Thaum uas siv cov bypass IAC muaj no tsuas muaj ib drawback - nws yeej ib txwm nws mus rau stabilize qhov kev sib hloov ntawm lub crankshaft. Txawm li cas los, thaum tsav tsheb qhov yuav tsum tau rau qhov no zoo disappears, raws li nws yog tsim nyog los tswj lub zog xwb thaum lub sij hawm switching speeds los yog braking.

Yuav ua li cas yog cov regulators

Muaj ob peb hom kaw ntawm lwm yam uas. Tej zaum cov feem ntau yooj yim - nws yog raws li nyob rau hauv lub solenoids. Thaum nws ua ib tug voltage mov, ncav us txog hlau tub ntxhais. Li ntawd, cov bypass zaj pib mus kaw, zuj zus lawm cov pa mov. Thiab vice versa. Tab sis muaj ib tug me ntsis drawback. Regulators ntawm no hom tsuas yog ob tug txaus - qhib thiab kaw channel. Nyob rau hauv thiaj li yuav tsim ib tug heev nplua hloov, koj feem ntau siv cov voltage mus rau lub solenoid. Ua ntej koj yuav mus saib lub IAC, kom paub tseeb tias thaum cov ignition powered rau.

Qhov thib ob hom - ib tug teb tswj. Lub hauv paus ntsiab lus ntawm cov lag luam yog yuav luag zoo ib yam li yav dhau los ib tug. Qhov txawv tsuas - yog lub xub ntiag ntawm lub rotor, uas ua qhib thiab kaw lub bypass channel. Tab sis lub feem ntau lug dhia idling, uas muaj 4 windings thiab ib tug magnet nyob rau hauv qhov zoo ntawm ib tug nplhaib. Nyob rau txhua ntawm lub windings amenable voltage los ntawm cov hluav taws xob kev tswj chav tsev. Raws li ib tug tshwm sim, lub rotor yog rotated, uas yuav qhib los yog kaw cov bypass channel. Hais tias xws li sib txawv nyob ntawm cov hom qauv ntawm IAC. Yuav ua li cas yog nws, koj yuav kawm tau.

Major puas tsuaj rau lub kaw ceev kev cai

Yog hais tias koj tseem tabtom mus kev tshawb nrhiav cav koj tus kheej, thiab koj muaj ib tug suspicion hais tias tus regulator ntawm idling yog tawm ntawm kev txiav txim, nws yog tsim nyog los paub qhov yooj yim tsis ua hauj lwm cov tsos mob. Thiab tus thawj heev yog hais tias lub ceev dhia yog idling. Tsis tas li ntawd thaum lub sij hawm cov roj paug tshwm sim thiaj li hu ua dai - turnovers rau ib lub sij hawm ncua los ntawm ib tug nqi. Nws yog tseem tau hais tias lub cav chaw thaum lub sij hawm ceev taug txuj kev nyuaj.

Thaum lub high-power tau txais kev pab, xws li cov teeb, cua txias, acoustics, muaj ib tug nco nyob rau hauv engine ceev. Nws yog tau hais tias lub cev muaj zog tej zaum yuav tsis pib. Nws yuav tsum tau muab sau tseg hais tias tsis muaj kev hloov IAC WHA yuav tsum tau. Nyob rau hauv cov kev tshwm sim tsis ua hauj lwm yuav tsum tau ua kom tiav hloov. Lub tsuas kos rau txoj cai - ib tug txhaws ntawm lub bypass channel. Yog li ntawd, ua ntej hloov IAC, qhov no channel purification.
