kev puas tsuaj ntawm theem regulator
Txheem
kev puas tsuaj ntawm theem regulator tej zaum yuav yog raws li nram no: nws pib ua tsis kaj siab tawg suab, freezes nyob rau hauv ib tug ntawm cov huab txoj hauj lwm, lub lag luam ntawm lub theem regulator solenoid valve yog cuam tshuam, ib qho kev ua yuam kev yog tsim nyob rau hauv lub computer nco.
Txawm hais tias koj tuaj yeem tsav nrog lub faulty theem regulator, koj yuav tsum to taub tias lub combustion engine sab hauv yuav tsis ua hauj lwm nyob rau hauv lub zoo hom. Qhov no yuav cuam tshuam rau cov roj noj thiab cov yam ntxwv dynamic ntawm lub combustion engine. Nyob ntawm qhov teeb meem uas tau tshwm sim nrog lub clutch, valve lossis theem regulator system tag nrho, cov tsos mob ntawm kev puas tsuaj thiab qhov ua tau ntawm lawv tshem tawm yuav txawv.
Txoj cai ntawm kev ua haujlwm ntawm theem regulator
txhawm rau txheeb xyuas seb yog vim li cas cov theem regulator yog tawg los yog nws lub valve yog lo, nws tsim nyog nkag siab txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm tag nrho cov kab ke. Qhov no yuav ua rau kev nkag siab zoo dua ntawm kev tawg thiab kev ua haujlwm ntxiv los kho lawv.
Ntawm qhov sib txawv ceev, lub cav combustion sab hauv tsis ua haujlwm tib yam. Rau qhov tsis muaj zog thiab qis qis, lub npe hu ua "theem nqaim" yog cov yam ntxwv, ntawm qhov kev tshem tawm cov pa tawm tsawg. Hloov pauv, kev kub ceev yog tus cwj pwm los ntawm "theem dav", thaum lub ntim ntawm cov roj tso tawm yog loj. Yog hais tias "dav theem" yog siv nyob rau hauv qis ceev, ces cov pa roj yuav sib tov nrog cov tshiab tuaj, uas yuav ua rau ib tug txo nyob rau hauv lub hwj chim ntawm lub internal combustion engine, thiab txawm yuav tsum tau. Thiab thaum "theem nqaim" tig rau ntawm kev kub ceev, nws yuav ua rau txo qis hauv lub zog ntawm lub cav thiab nws cov dynamic.
Muaj ntau ntau hom theem regulator systems. VVT (Variable Valve Timing), tsim los ntawm Volkswagen, CVVT - siv los ntawm Kia thiab Hyindai, VVT-i - siv los ntawm Toyota thiab VTC - ntsia rau Honda xyaw, VCP - Renault theem shifters, Vanos / Ob chav Vanos - ib qho system siv hauv BMW . Ntxiv mus, peb yuav xav txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov theem tswj kev siv cov piv txwv ntawm lub tsheb Renault Megan 2 nrog 16-valve ICE K4M, vim tias nws tsis ua haujlwm yog "tus kab mob thaum yau" ntawm lub tsheb no thiab nws cov tswv feem ntau ntsib cov theem tsis ua haujlwm. tus tswj.
Kev tswj yuav siv qhov chaw los ntawm lub solenoid valve, cov roj mov uas yog tswj los ntawm hluav taws xob cov teeb liab nrog qhov sib txawv ntawm 0 lossis 250 Hz. Tag nrho cov txheej txheem no yog tswj los ntawm ib qho hluav taws xob tswj chav tsev raws li cov teeb liab los ntawm lub cav combustion sensors. Cov theem regulator yog switched nrog ib tug nce load ntawm lub internal combustion engine (rpm tus nqi ntawm 1500 mus rau 4300 rpm) thaum muaj raws li nram no tej yam kev mob:
- serviceable crankshaft txoj hauj lwm sensors (DPKV) thiab camshafts (DPRV);
- tsis muaj kev puas tsuaj hauv cov roj txhaj tshuaj;
- pom tus nqi pib ntawm theem txhaj tshuaj;
- Qhov ntsuas kub ntawm qhov ntsuas kub tsis pub dhau +10 ° ... + 120 ° C;
- nce cav roj kub.
Kev rov qab los ntawm theem regulator mus rau nws qhov qub txoj hauj lwm tshwm sim thaum lub ceev txo nyob rau hauv tib yam kev mob, tab sis nrog rau qhov sib txawv uas ib tug xoom theem sib txawv yog xam. Hauv qhov no, lub xauv plunger thaiv lub tshuab. Yog li, "culprits" ntawm kev puas tsuaj ntawm cov theem regulator tuaj yeem tsis yog nws tus kheej xwb, tab sis kuj yog lub solenoid valve, sab hauv combustion engine sensors, breakdowns nyob rau hauv lub cev muaj zog, malfunctions ntawm lub computer.
Cov cim qhia ntawm qhov tawg theem regulator
Qhov ua tiav lossis ib nrab tsis ua haujlwm ntawm theem regulator tuaj yeem txiav txim los ntawm cov cim hauv qab no:
- Ua kom lub suab nrov ntawm lub cav combustion sab hauv. Rov qab clanging suab yuav los ntawm qhov chaw camshaft installation. Qee tus neeg tsav tsheb hais tias lawv zoo ib yam li kev ua haujlwm ntawm lub cav diesel.
- Kev ua haujlwm tsis ruaj khov ntawm lub cav combustion hauv ib qho ntawm cov qauv. Lub cev muaj zog tuaj yeem ua haujlwm tsis zoo, tab sis nrawm nrawm thiab poob lub zog. Los yog vice versa, nws yog ib txwm tsav, tab sis "choke" ntawm idle. Nyob rau ntawm lub ntsej muag ntawm ib qho kev txo qis hauv cov zis hluav taws xob.
- Kev siv roj ntau ntxiv. Ib zaug ntxiv, hauv qee hom kev ua haujlwm ntawm lub cev muaj zog. Nws raug nquahu kom kuaj xyuas cov roj noj hauv cov dynamic uas siv lub computer on-board lossis cov cuab yeej kuaj mob.
- Nce toxicity ntawm cov pa pa. Feem ntau lawv cov naj npawb loj dua, thiab lawv tau txais cov ntxhiab tsw zoo li roj ntau dua li ua ntej.
- Kev siv roj cav nce ntxiv. Tej zaum nws yuav pib kub hnyiab tawm (nws theem hauv crankcase txo) lossis poob nws cov khoom ua haujlwm.
- Tsis ruaj khov rpm tom qab lub cav pib. Qhov no feem ntau kav li 2-10 vib nas this. Nyob rau tib lub sijhawm, lub crackle los ntawm theem regulator muaj zog, thiab tom qab ntawd nws txo qis me ntsis.
- Tsim kom muaj qhov yuam kev ntawm misalignment ntawm lub crankshaft thiab camshafts los yog txoj hauj lwm ntawm lub camshaft. Cov tshuab sib txawv tuaj yeem muaj cov lej sib txawv. Piv txwv li, rau Renault, qhov yuam kev nrog code DF080 ncaj qha qhia teeb meem nrog Fazi. Lwm lub tshuab feem ntau tau yuam kev p0011 lossis p0016, qhia tias lub kaw lus tsis sib xws.
Thov nco ntsoov tias ntxiv rau qhov no, thaum lub sijhawm tswj hwm tsis ua haujlwm, tsuas yog ib feem ntawm cov tsos mob qhia tau tshwm sim lossis lawv tshwm sim txawv ntawm cov tshuab sib txawv.
Ua rau tsis ua hauj lwm ntawm theem regulator
breakdowns yog muab faib precisely los ntawm theem regulator thiab los ntawm nws tswj valve. Yog li, cov laj thawj rau kev tawg ntawm theem regulator yog:
- Rotary mechanism hnav (paddles / paddles). Raws li ib txwm muaj, qhov no tshwm sim rau lub ntuj tsim, thiab nws raug pom zoo kom hloov cov theem regulators txhua 100 ... 200 txhiab kilometers. Cov roj tsis zoo los yog cov roj tsis zoo tuaj yeem ua kom hnav.
- Saib kuj los yog tsis sib haum ntawm cov txheej txheem ntawm kev tig lub kaum sab xis ntawm theem regulator. Qhov no feem ntau tshwm sim vim lub fact tias lub teb mechanism ntawm lub theem regulator nyob rau hauv nws cov vaj tse tshaj lub permissible rotation kaum vim hlau hnav.
Tab sis cov laj thawj rau kev tawg ntawm vvt valve txawv.
- Ua tsis tiav ntawm theem regulator valve foob. Rau Renault Megan 2 lub tsheb, cov theem regulator valve yog ntsia rau hauv ib qho chaw so nyob rau hauv pem hauv ntej ntawm lub combustion engine, qhov twg muaj av ntau. Raws li, yog tias lub thawv ntim khoom poob nws qhov nruj, ces plua plav thiab av los ntawm sab nraud sib xyaw nrog cov roj thiab nkag mus rau hauv qhov chaw ua haujlwm ntawm lub tshuab. Yog li ntawd, valve jamming thiab hnav ntawm lub teb mechanism ntawm tus regulator nws tus kheej.
- Teeb meem nrog hluav taws xob Circuit Court ntawm lub valve. Qhov no tej zaum yuav yog nws qhov kev tawg, kev puas tsuaj rau kev sib cuag, kev puas tsuaj rau lub rwb thaiv tsev, luv luv Circuit Court rau rooj plaub lossis rau lub zog xaim, txo qis lossis nce hauv kev tiv thaiv.
- Ingress ntawm yas chips. Nyob rau theem regulators, cov hniav feem ntau yog ua los ntawm yas. Thaum lawv hnav tawm, lawv hloov lawv cov duab geometry thiab poob ntawm lub rooj zaum. Ua ke nrog cov roj, lawv nkag mus rau lub valve, disintegrate thiab crushed. Qhov no tuaj yeem ua rau tsis tiav stroke ntawm lub valve qia los yog ua tiav jamming ntawm qia.
Tsis tas li ntawd, yog vim li cas rau qhov tsis ua hauj lwm ntawm theem regulator yuav dag nyob rau hauv qhov tsis ua hauj lwm ntawm lwm yam hais txog:
- Cov teeb liab tsis raug los ntawm DPKV thiab / lossis DPRV. Qhov no tej zaum yuav yog vim ob qho tib si rau cov teeb meem nrog cov sensors qhia, thiab rau qhov tseeb hais tias cov theem regulator tau hnav tawm, vim hais tias lub camshaft los yog crankshaft nyob rau hauv ib txoj hauj lwm uas mus dhau qhov tso cai txwv ntawm ib qho chaw nyob rau hauv lub sij hawm. Nyob rau hauv cov ntaub ntawv no, ua ke nrog cov theem regulator, koj yuav tsum tau mus xyuas lub crankshaft txoj hauj lwm sensor thiab xyuas DPRV.
- ECU teeb meem. Muaj tsawg zaus, software tsis ua haujlwm tshwm sim hauv chav tswj hluav taws xob, thiab txawm tias tag nrho cov ntaub ntawv raug, nws pib muab qhov yuam kev, suav nrog kev cuam tshuam rau theem regulator.
Dismantling thiab ntxuav cov theem regulator
Tshawb xyuas cov haujlwm ntawm fazik tuaj yeem ua tsis tau dismantling. Tab sis ua ib qho kev ntsuam xyuas ntawm kev hnav ntawm cov theem regulator, nws yuav tsum tau muab tshem tawm thiab disassembled. Yuav kom nrhiav tau qhov twg nws yog, koj yuav tsum tau mus rau pem hauv ntej ntug ntawm lub camshaft. Nyob ntawm tus tsim ntawm lub cev muaj zog, lub dismantling ntawm theem regulator nws tus kheej yuav txawv. Txawm li cas los xij, yog tias nws tuaj yeem, lub sijhawm siv lub sijhawm raug pov los ntawm nws lub casing. Yog li ntawd, koj yuav tsum tau muab kev nkag mus rau txoj siv, thiab txoj siv nws tus kheej yuav tsum raug tshem tawm.
Tom qab disconnecting lub valve, nco ntsoov xyuas qhov xwm txheej ntawm lub lim mesh. Yog tias nws qias neeg, nws yuav tsum tau ntxuav (ntxuav nrog lub tshuab ntxhua khaub ncaws). txhawm rau ntxuav lub mesh, koj yuav tsum ua tib zoo thawb nws sib nrug ntawm qhov chaw snapping thiab dismantle nws los ntawm lub rooj zaum. Cov mesh tuaj yeem ntxuav hauv cov roj av lossis lwm cov kua ntxuav uas siv cov txhuam hniav lossis lwm yam khoom tsis nruj.
Cov theem regulator valve nws tus kheej kuj tseem tuaj yeem ntxuav cov roj thiab cov pa roj carbon deposits (ob leeg sab nraud thiab sab hauv, yog tias nws tsim tso cai rau nws) siv lub tshuab nqus tsev carb. Yog hais tias lub valve huv si, ces koj tuaj yeem mus xyuas nws.
Yuav ua li cas xyuas cov theem regulator
Muaj ib txoj hauv kev yooj yim rau kev kuaj xyuas seb cov theem regulator nyob rau hauv lub combustion engine puas ua hauj lwm los yog tsis. Rau qhov no, tsuas yog ob txoj hlua nyias nyias txog ib thiab ib nrab meters ntev yog xav tau. Lub ntsiab ntawm daim tshev yog raws li nram no:
- Tshem tawm lub ntsaws los ntawm qhov txuas ntawm cov roj xa hluav taws xob mus rau theem regulator thiab txuas cov xaim npaj rau ntawd.
- Lwm qhov kawg ntawm ib qho ntawm cov xov hlau yuav tsum txuas nrog ib qho ntawm cov roj teeb terminals (polarity tsis tseem ceeb hauv qhov no).
- Cia lwm qhov kawg ntawm ob lub xov hlau hauv limbo rau tam sim no.
- Pib lub cav txias thiab cia nws mus ua haujlwm. Nws yog ib qho tseem ceeb uas cov roj hauv lub cav txias!
- Txuas qhov kawg ntawm lub xov tooj thib ob mus rau lub roj teeb thib ob.
- Yog hais tias lub combustion engine sab hauv tom qab ntawd pib "cua", ces cov theem regulator ua hauj lwm, txwv tsis pub - tsis yog!
Lub solenoid valve ntawm theem regulator yuav tsum tau kuaj xyuas raws li cov hauv qab no algorithm:
- Tom qab xaiv hom kev ntsuas kev tiv thaiv ntawm lub tester, ntsuas nws ntawm lub valve terminals. Yog tias peb tsom mus rau cov ntaub ntawv ntawm Megan 2 phau ntawv qhia, tom qab ntawd ntawm huab cua kub ntawm + 20 ° C nws yuav tsum nyob rau hauv thaj tsam ntawm 6,7 ... 7,7 Ohm.
- Yog tias qhov tsis kam qis dua, nws txhais tau hais tias muaj luv luv Circuit Court; yog tias ntau dua, nws txhais tau tias qhib Circuit Court. Txawm li cas los xij, cov li qub tsis tau kho, tab sis hloov nrog cov tshiab.
Kev ntsuas kev tiv thaiv tuaj yeem ua tsis tau dismantling, txawm li cas los xij, cov khoom siv ntawm lub valve yuav tsum tau kuaj xyuas. Rau qhov no koj yuav xav tau:
- Los ntawm 12 Volt lub zog hluav taws xob (tsheb roj teeb), siv qhov hluav taws xob nrog txuas ntxiv rau lub valve hluav taws xob txuas.
- Yog tias lub valve tau txais kev pabcuam thiab huv, ces nws lub piston yuav txav mus. Yog tias qhov hluav taws xob raug tshem tawm, tus pas nrig yuav tsum rov qab mus rau nws qhov qub.
- tom ntej no koj yuav tsum tau xyuas qhov sib txawv nyob rau hauv lub heev ncua txoj hauj lwm. Nws yuav tsum tsis pub ntau tshaj 0,8 hli (koj tuaj yeem siv lub ntsuas hluav taws xob los kuaj xyuas valve clearances). Yog tias nws tsawg dua, ces lub valve yuav tsum tau ntxuav raws li cov algorithm tau piav qhia saum toj no. Tom qab ntxuav, yuav tsum tau kuaj xyuas hluav taws xob thiab tshuab, thiab tom qab ntawd yuav tsum txiav txim siab los hloov nws. rov ua dua.
Phase regulator yuam kev
Yog tias qhov yuam kev DF2 tau tsim nyob rau hauv chav tswj ntawm Renault Megan 080 (ib txoj hlua rau kev hloov cov yam ntxwv ntawm lub camshaft, qhib Circuit Court), ces koj yuav tsum xub xyuas lub valve raws li cov txheej txheem saum toj no. Yog tias nws ua haujlwm zoo, ces qhov no koj yuav tsum tau "ntiv nplhaib" raws li cov xaim hluav taws xob los ntawm lub valve nti mus rau chav tswj hluav taws xob.
Feem ntau, teeb meem tshwm sim hauv ob qhov chaw. Thawj yog nyob rau hauv cov hlua hlau uas mus los ntawm ICE nws tus kheej mus rau ICE tswj chav tsev. Qhov thib ob yog nyob rau hauv lub connector nws tus kheej. Yog hais tias cov xov hlau tsis zoo, ces saib ntawm qhov txuas. Nyob rau tib lub sijhawm, cov pins ntawm lawv tsis raug kaw. Txhawm rau kom nruj lawv, koj yuav tsum ua cov hauv qab no:
- tshem cov yas yas los ntawm qhov txuas (rub mus);
- Tom qab ntawd, nkag mus rau cov neeg sab hauv yuav tshwm sim;
- Ib yam li ntawd, nws yog ib qho tsim nyog yuav tsum rhuav tshem lub nraub qaum ntawm lub cev;
- Tom qab ntawd, hloov mus rau ib qho thiab ob lub teeb liab xaim los ntawm sab nraub qaum (nws yog qhov zoo dua los ua lem, thiaj li tsis txhob cuam tshuam lub pinout);
- ntawm lub davhlau ya nyob twg, koj yuav tsum tau ceev cov terminals nrog kev pab los ntawm ib co khoom ntse;
- muab txhua yam rov qab rau hauv nws txoj haujlwm qub.
Disabling lub theem regulator
Ntau tus neeg tsav tsheb muaj kev txhawj xeeb txog cov lus nug - nws puas tuaj yeem tsav tsheb nrog lub faulty regulator? Cov lus teb yog yog, koj tuaj yeem ua tau, tab sis koj yuav tsum nkag siab txog qhov tshwm sim. Yog tias, vim li cas, koj tseem txiav txim siab tua lub sijhawm tswj hwm, koj tuaj yeem ua nws zoo li no (xav txog tib yam Renault Megan 2):
- disconnect lub plug los ntawm connector ntawm cov roj mov valve mus rau theem regulator;
- Raws li qhov tshwm sim, kev ua yuam kev DF080 yuav tshwm sim, thiab tej zaum yuav muaj lwm yam ntxiv nyob rau hauv lub xub ntiag ntawm concomitant breakdowns;
- Txhawm rau kom tshem tawm qhov yuam kev thiab "dag" chav tswj, koj yuav tsum tau ntxig ib qho hluav taws xob tiv thaiv nrog qhov tsis kam ntawm 7 ohms ntawm ob lub terminals ntawm lub ntsaws (raws li tau hais los saum toj no - 6,7 ... 7,7 ohms lub caij sov);
- rov pib dua qhov yuam kev uas tshwm sim hauv chav tswj programmatically lossis los ntawm kev txiav lub roj teeb tsis zoo rau ob peb feeb;
- securely fasten lub tshem tawm plug nyob rau hauv lub engine compartment kom nws tsis yaj thiab cuam tshuam nrog lwm yam.
