Hauv kab lus no, IAC yuav raug txiav txim siab, nws yog dab tsi, lub hauv paus ntsiab lus ntawm kev ua haujlwm, lub ntsiab tsis tseem ceeb. Nws kuj tseem yuav tham txog thaum twg nws yog qhov tsim nyog los hloov qhov tsis siv neeg ceev tswj ntawm VAZ tsheb. Koj paub tias lub tsheb niaj hnub yog crammed nrog ntau sensors thiab actuators. Cov no suav nrog tus tswj kev ceev nrawm. Nrog nws cov kev pab, lub cav ceev yog tswj. Yog tias IAC ua tsis tiav, lub cev muaj zog pib ua haujlwm tsis zoo, cov tsos mob xws li kev hloov tsis ruaj khov ntawm lub crankshaft tshwm sim, nws qhov nrawm tas li dhia. Qee zaum, nws tuaj yeem ua rau lub cav nres thiab tsis pib.

Dab tsi yog tus tswj ceev nrawm?

Pib nrog, nws tsim nyog xav txog qhov pom sab nraud thiab sab hauv ntawm IAC. Nws yog dab tsi, koj yuav kawm los ntawm kab lus no. Nws yog ntsia ze ntawm lub throttle valve, nrog rau nws cov kev pab, lub crankshaft ceev yog tswj nyob rau hauv ib theem ntawm 700 mus rau 900 rpm. Qhov no yog ua los ntawm kev kho cov cua nkag mus rau lub throttle los ua ke. Sab nraud, lub idle speed regulator zoo li lub thawv yas me me, sab hauvuas yog me me stepper motors (los yog solenoid). Tab sis qee cov qauv muaj cov duab ntawm lub tog raj kheej, ua los ntawm cov hlau. Stepper lub cev muaj zog lossis solenoid tsav lub pas hlau uas qhib thiab kaw cov pa cua.

Cav khiav ntawm XX

Kev ua haujlwm ntawm lub cav ntawm qhov ceev tshaj plaws yog hom nyuaj rau nws. Nws tsim nyog pib nrog qhov tseeb tias roj nrog cua maj mam nkag mus rau hauv chav combustion, yog li ntawd, kev tsim ntawm cov khoom sib xyaw ua haujlwm tsis zoo. Nws kuj tseem yuav tsum tau nco ntsoov tias muaj lub siab me me hauv lub cav ntim manifold, yog li cov pa roj tuaj yeem rov qab mus rau hauv lub combustion chamber. Los ntawm qhov no peb tuaj yeem txiav txim siab tias muaj qhov txo qis hauv kev ua haujlwm, nce hauv cov pa toxicity, thiab hnav ntau dhau ntawm cov ntsiab lus ntawm lub tog raj kheej-piston pawg. Nws yog tsim nyog sau cia tias cov cuab yeej tsis kim heev. Tus nqi qis ntawm kev tswj hwm tus nqi ntawm 400-500 rubles.

Idle control

Yog tias koj nco qab lub cav carburetor, ces lub cav tsis ua haujlwm ceev tau tswj hwm nrog kev pab los ntawm cov ntsia hlau tshwj xeeb. Thaum lub sij hawm tuning txheej txheem, nws yog tsim nyog los tswj cov pa oxygen cov ntsiab lus nyob rau hauv lub tso pa gases, lub crankshaft ceev. Cov txheej txheem nws tus kheej yog siv sijhawm ntev heev thiab xav tau tus kws tshaj lij uas tsim nyog los nqa tawm. Thaum thawj zaug yuam kev roj txhaj tshuaj tshwm sim, cov txheej txheem tau yooj yim heev.

Qhov tseeb, IAC, nws yog dab tsi, tau tham hauv tsab xov xwm, yog tus actuator, tsis yog sensor. Nws raug khinrog rau chav tswj hluav taws xob uas sau tag nrho cov ntaub ntawv ntawm kev ua haujlwm ntawm lub cev muaj zog hauv lub sijhawm. Raws li cov ntaub ntawv tau txais, lub tsheb ECU saib xyuas txhua qhov tseem ceeb tshaj plaws ntawm lub cav combustion sab hauv. Nws yog ib qho tsim nyog sau cia tias tus qauv tsim ntawm qhov tsis siv neeg ceev tswj yog qhov qub, txij li lub tshuab hluav taws xob siv cov kev hloov pauv txawv kiag li.

How RHX ua haujlwm

Yog li, saum toj no nws tau txiav txim siab tias qhov kev tswj hwm qhov nrawm yog qhov xav tau rau. Txhua yam uas tau piav qhia tsuas yog tuaj yeem pom tau yog tias, ntawm qhov tsis ua haujlwm, huab cua yog nkag los ntawm lub qhov rooj valve. Qhov no tshwm sim nrog kev pab los ntawm bypass channel. Nyob ntawm seb qhib qhov channel no li cas, huab cua hloov pauv. Thov nco ntsoov tias nyob rau hauv qhov xwm txheej ntawm kev ua haujlwm tsis zoo ntawm tus tswj kev ceev ceev, "check engine" teeb tsis teeb nyob rau hauv feem ntau. Thiab nco ntsoov tias lub regulator tsis yog sensor. IAC yog tus actuator vim nws tsis ntsuas dab tsi.

Thaum siv lub bypass IAC, tsuas yog qhov tsis zoo yog tias nws ib txwm sim ua kom ruaj khov ntawm crankshaft ceev. Muaj tseeb tiag, thaum tsav tsheb, qhov xav tau ntawm qhov kev xyaum no yuav ploj mus, vim tias nws yog qhov tsim nyog yuav tsum ua kom ruaj khov ntawm qhov ceev tsuas yog thaum lub iav hloov lossis nres.

Dab tsi yog cov tswj hwm

Muaj ntau ntau hom kev tswj ceev ceev. Tej zaum qhov yooj yim tshaj yog raws li cov solenoids. Thaum qhov hluav taws xob raug siv rau nws, cov tub ntxhais hlau yog rub tawm. Yog li ntawd, lub bypass channel pib kaw, txo cov cua nkag. Thiab vice versa. Tab sis muaj ib tug me me drawback. Regulators ntawm hom no tsuas muaj ob txoj haujlwm - qhib thiab kaw channel. Txhawm rau hloov kho kom zoo, koj yuav tsum siv qhov hluav taws xob rau lub solenoid ntau zaus. Ua ntej kuaj IAC, xyuas kom tseeb tias nws muaj hwj chim thaum lub teeb hluav taws xob qhib.

Hom thib ob yog lub tshuab hluav taws xob teb. Lub hauv paus ntsiab lus ntawm kev ua haujlwm yuav luag zoo ib yam li yav dhau los. Qhov sib txawv tsuas yog qhov muaj lub rotor uas qhib thiab kaw cov bypass channel. Tab sis tus stepping idle speed controller, uas muaj 4 windings thiab ib tug hlau nplaum nyob rau hauv daim ntawv ntawm ib lub nplhaib, tau dhau los ua ntau. Txhua lub windings yog energized los ntawm ib qho hluav taws xob tswj chav tsev. Yog li ntawd, lub rotor tig, uas qhib los yog kaw lub bypass channel. Cov no yog qhov sib txawv ntawm cov qauv IAC sib txawv. Nws yog dab tsi, koj muaj peev xwm assimilate.

Lub ntsiab tawg ntawm tus tswj ceev nrawm

Yog tias koj tab tom sim kuaj xyuas lub tshuab ua haujlwm ntawm koj tus kheej, thiab koj xav tias lub tshuab hluav taws xob ceev tsis ua haujlwm, koj yuav tsum paub cov tsos mob tseem ceeb ntawm kev tawg. Thiab thawj heev yog tias cov revs dhia ntawm idle. Tsis tas li ntawd, thaum lub sij hawm tso tawm ntawm cov pa roj, lub thiaj li hu ua freeze tshwm sim - lub revolutions yog ncua rau ib pliag ntawm ib tug nqi. Nws kuj tseem ua tau tias lub cav nres thaum taug kev nrawm.

Thaum koj qhib rau cov neeg siv khoom muaj zog, xws li lub teebheadlights, cua txias, acoustics, muaj ib tug txo nyob rau hauv lub cav ceev. Nws yog qhov ua tau tias lub cav yuav tsis pib txhua. Nws yog ib qho tsim nyog sau cia tias IAC VAZ tsis xav tau kev teeb tsa. Nyob rau hauv cov ntaub ntawv ntawm tsis ua hauj lwm, yuav tsum tau ib tug tag nrho hloov. Tsuas yog kev zam rau txoj cai yog clogging ntawm bypass channel. Yog li ntawd, ua ntej hloov IAC, ntxuav cov channel no.
