Yog vim li cas lub txim taws dub

Tsos dub tshauv ntawm lub txim plugs tuaj yeem qhia tus tswv lub tsheb txog cov teeb meem uas nyob hauv nws lub tsheb. Cov laj thawj rau qhov tshwm sim no tuaj yeem yog cov roj tsis zoo, teeb meem hluav taws xob, tsis sib haum xeeb hauv cov huab cua sib xyaw, lossis cov carburetor tsis raug, thiab lwm yam. Tag nrho cov teeb meem no tuaj yeem kuaj pom tau yooj yim tsuas yog los ntawm kev saib cov pob hluav taws dub.

Ua tau ua rau khaus

Ua ntej teb cov lus nug vim li cas cov tswm ciab dub, koj yuav tsum txiav txim siab ua li cas lawv tig dub?. Tom qab tag nrho, nws nyob ntawm qhov kev taw qhia mus nrhiav. uas yog, tswm ciab tuaj yeem ua rau tag nrho ua ke, lossis tej zaum tsuas yog ib lossis ob ntawm cov teeb. kuj, ib tug tswm ciab tuaj yeem tig dub rau ntawm ib sab, lossis tej zaum raws tag nrho txoj kab. kuj paub qhov txawv qhov thiaj li hu ua "ntub" thiab "qhuav" soot.

Nws yuav tsum tau muab sau tseg tias tus nqi ntawm cov tsos thiab qhov xwm ntawm soot ncaj qha nyob ntawm qhov uas twb muaj lawm malfunctions (yog tias muaj):

• Nagar ntawm cov tswm ciab tshiab pib tsim tsawg kawg tom qab 200-300 km ntawm kev khiav. Ntxiv mus, nws yog ntshaw kom tsav tsheb raws txoj kev loj nrog kwv yees li tib lub ceev thiab thauj khoom ntawm lub cav combustion sab hauv. Yog li ntawd, cov tswm ciab yuav ua hauj lwm nyob rau hauv lub optimum hom, thiab nws yuav ua tau ntau objectively ntsuam xyuas cov mob ntawm lub tsheb units.
• Tus nqi thiab hom av yog nyob ntawm qhov zoo ntawm cov roj siv. Yog li ntawd, sim refuel nyob rau hauv pov thawj cov chaw nres tsheb roj, thiab tsis tsav tsheb ntawm cov roj av los yog cov sib tov sib xyaw. Txwv tsis pub, nws yuav nyuaj rau tsim kom muaj qhov ua rau muaj qhov tshwm sim ntawm soot (yog tias muaj).
• Nyob rau hauv lub carburetor sab hauv combustion engine, idle speed yuav tsum raug teem kom raug.

Tam sim no cia peb mus rau lo lus nug ntawm yog vim li cas cov pob khaus dub tshwm rau ntawm lub txim hluav taws xob. Tej zaum 11 yog vim li cas:

1. Yog tias koj pom blackening ntawm ib sab, ces feem ntau qhov no yog tshwm sim los ntawm valve burnout. Ntawd yog, cov hmoov tshauv ntawm lub tswm ciab ntog hauv qab mus rau sab electrode (thiab tsis yog rau hauv nruab nrab).
2. Qhov ua rau cov tswm ciab dub tuaj yeem yog lub valve burnout. Qhov xwm txheej zoo ib yam li yav dhau los. Cov pa roj carbon deposits tuaj yeem nkag mus rau hauv qab electrode.
3. ib qho tsis raug xaiv glow tus naj npawb ntawm lub tswm ciab ua rau tsis yog nws qhov kev puas tsuaj hauv kev ua haujlwm ntxiv, tab sis kuj tsis sib xws blackening ntawm thawj. Yog hais tias tus lej hais me me, ces cov duab ntawm lub khob hliav qab yuav hloov. Yog hais tias nws loj, ces tsuas yog sab saum toj ntawm lub khob hliav qab yuav tig dub, thiab lub cev yuav dawb.
   Tus naj npawb glow yog tus nqi uas qhia txog lub sijhawm nws siv rau lub tswm ciab kom ncav cuag glow ignition. Nrog ib tug loj tus naj npawb, nws heats li tsawg, feem, lub tswm ciab txias, thiab nrog ib tug me me, nws yog kub. Nruab lub txim hluav taws xob nrog lub teeb ci uas tau teev tseg los ntawm cov chaw tsim khoom hauv lub tshuab hluav taws xob sab hauv.
4. Ib txheej txheej xim dub ntawm cov tswm ciab qhia tias lig ignition.
5. Cov tswm ciab dub ntawm lub tshuab txhaj tshuaj lossis carburetor tuaj yeem tshwm sim vim qhov tseeb tias cov pa roj sib xyaw ua los ntawm lawv muaj ntau dhau. Raws li thawj zaug, muaj qhov ua tau zoo ntawm kev ua haujlwm tsis raug ntawm huab cua huab cua txaus sensor (DMRV), uas muab cov ntaub ntawv rau lub khoos phis tawj txog cov khoom sib xyaw. Nws tseem ua tau tias cov roj injectors tau xau. Vim li no, roj av nkag mus rau hauv lub tog raj kheej txawm tias lub nozzle kaw. Raws li rau lub carburetor, cov laj thawj tej zaum yuav yog cov hauv qab no yog vim li cas - kho tsis raug roj theem hauv carburetor, depressurization ntawm rab koob kaw-off valve, roj twj tso kua mis tsim siab dhau (tus tsav pusher protrudes muaj zog), depressurization ntawm ntab los yog nws. grazing qab phab ntsa ntawm lub chamber.

   "Dry" soot ntawm ib tug tswm ciab

6. Qhov tseem ceeb coj los yog depressurization ntawm lub pob valve ntawm lub hwj chim hom economizer ntawm carburetor ICEs. Ntawd yog, ntau roj nkag mus rau hauv lub cav combustion tsis tsuas yog nyob rau hauv lub zog, tab sis kuj nyob rau hauv ib txwm hom.
7. Lub lim cua txhaws tuaj yeem ua rau lub txim hluav taws xob dub. Nco ntsoov xyuas nws tus mob thiab hloov yog tias tsim nyog. kuj xyuas cov cua damper actuator.
8. Teeb meem nrog lub ignition system - ib tug incorrectly teem ignition lub kaum sab xis, kev ua txhaum ntawm lub rwb thaiv tsev ntawm high-voltage nyob ntawm tej, kev ua txhaum ntawm kev ncaj ncees ntawm lub cover los yog distributor slider, breakdowns nyob rau hauv lub lag luam ntawm lub ignition kauj, teeb meem nrog lub tswm ciab lawv tus kheej. Cov laj thawj saum toj no tuaj yeem ua rau muaj kev cuam tshuam hauv kev tawg paj, lossis lub txim tsis muaj zog. Vim li no, tsis yog tag nrho cov roj hlawv tawm, thiab lub teeb ci dub tshwm rau ntawm cov tswm ciab.
9. Teeb meem nrog lub valve mechanism ntawm lub internal combustion engine. uas yog, nws tuaj yeem yog qhov kub hnyiab ntawm cov li qub, lossis lawv cov qhov tsis hloov kho thermal. Qhov tshwm sim ntawm qhov no yog tsis tiav combustion ntawm huab cua-roj sib tov thiab tsim ntawm soot on tswm ciab.
10. Hauv cov tsheb txhaj tshuaj, nws muaj peev xwm hais tias cov roj regulator tsis raug txiav txim, thiab muaj ntau dhau ntawm cov roj tsheb ciav hlau.
11. Tsawg compression nyob rau hauv lub tog raj kheej sib haum mus rau lub txim taws dub. Yuav ua li cas xyuas compression koj tuaj yeem nyeem hauv lwm tsab xov xwm.

Feem ntau, thaum lub ignition lig yog teem thiab khiav ntawm ib tug enriched roj-cua sib tov, cov nram qab no tshwm sim:

• misfiring (yuam kev P0300 tshwm ntawm txhaj tshuaj ICEs);
• teeb meem nrog pib lub combustion engine;
• kev ua haujlwm tsis ruaj khov ntawm lub tshuab hluav taws xob sab hauv, tshwj xeeb tshaj yog thaum tsis muaj zog, thiab vim li ntawd, nce qib ntawm kev co.

Ntxiv mus, peb yuav qhia koj yuav ua li cas tshem tawm cov kev puas tsuaj uas tau teev tseg thiab yuav ua li cas ntxuav lub txim hluav taws xob.

Yuav ua li cas thaum soot tshwm

Ua ntej ntawm tag nrho cov, koj yuav tsum nco ntsoov tias cov roj muaj kuab paug thiab overheating, uas ua rau soot nyob rau hauv lub txim plugs, txaus ntshai heev rau lub ignition system. Overheating yog qhov txaus ntshai heev, vim tias nws muaj peev xwm ua tsis tiav ntawm cov hluav taws xob ntawm cov tswm ciab yam tsis muaj peev xwm rov qab los.

Yog tias tsuas yog ib lub tswm ciab dub tshwm rau ntawm koj lub tsheb, ces koj tuaj yeem kuaj xyuas qhov kev puas tsuaj los ntawm kev sib pauv cov tswm ciab. Yog tias tom qab ntawd tus tswm ciab tshiab kuj tig dub, thiab qhov qub tshem tawm, nws txhais tau hais tias qhov teeb meem tsis nyob hauv tswm ciab, tab sis nyob rau hauv lub tog raj kheej. Thiab yog tias tsis muaj dab tsi hloov, ces cov lus nug tshwm sim txog qhov ua tau zoo ntawm lub tswm ciab nws tus kheej.

Cov roj deposits

Qee zaum, tswm ciab yuav ntub thiab dub. Qhov feem ntau ua rau qhov tseeb yog qhov ingress ntawm roj mus rau hauv lub combustion chamber. Cov tsos mob ntxiv ntawm qhov kev puas tsuaj no yog raws li hauv qab no:

Roj rau lub tswm ciab

• nyuaj pib ntawm lub internal combustion engine;
• omissions hauv kev ua haujlwm ntawm lub tog raj kheej sib xws;
• ICE twitches thaum ua haujlwm;
• cov pa luam yeeb xiav los ntawm qhov tso pa tawm.

Roj tuaj yeem nkag mus rau hauv chav combustion hauv ob txoj hauv kev - los ntawm hauv qab lossis los ntawm sab saud. Nyob rau hauv thawj rooj plaub, nws nkag los ntawm lub piston rings. Thiab qhov no yog ib qho kev phem heev, vim nws feem ntau hem cav overhaul. Nyob rau hauv tsawg zaus, koj tuaj yeem ua nrog lub decoking ntawm lub cev muaj zog. Yog hais tias cov roj nkag mus rau hauv lub combustion chamber los ntawm sab saum toj, ces nws mus los ntawm lub tog raj kheej taub hau raws li lub valve qhia. Yog vim li cas rau qhov no yog hnav ntawm valve qia seals. Txhawm rau tshem tawm qhov kev puas tsuaj no, koj tsuas yog yuav tsum xaiv cov kaus mom tshiab, zoo thiab hloov lawv.

Nagar ntawm lub insulator

Liab soot rau ntawm ib tug tswm ciab

Qee zaum, cov pa roj carbon deposits uas ib txwm tsim nyob rau hauv lub combustion chamber tuaj yeem tawg tawm ntawm lub piston ntawm lub cav ceev ceev thiab lo rau lub txim hluav taws xob insulator. Qhov tshwm sim ntawm qhov no yuav yog qhov khoob hauv kev ua haujlwm ntawm lub tog raj kheej sib thooj. Nyob rau hauv cov ntaub ntawv no, lub internal combustion engine yuav "troit". Qhov no yog qhov teeb meem tsis zoo tshaj plaws, yog vim li cas cov hluav taws xob tig dub. Koj tuaj yeem tshem tawm nws yooj yim los ntawm kev tu lawv qhov chaw lossis hloov lawv nrog cov tshiab.

Yog tias koj lub cav combustion muaj tswm ciab dub thiab liab, ces qhov no txhais tau hais tias koj yog pouring roj nrog ib tug ntau ntawm cov additives nrog hlau. Nws tsis tuaj yeem siv tau ntev, vim tias lub sijhawm dhau mus, cov hlau tso nyiaj tsim cov txheej txheem hluav taws xob rau ntawm qhov chaw ntawm lub tswm ciab insulator. Tshav kub yuav deteriorate thiab lub tswm ciab yuav tsis ntev.

Ntxuav cov taub hau

Ntxuav cov taub hau

Cov tswm ciab yuav tsum tau ntxuav tsis tu ncua, nrog rau tshuaj xyuas lawv tus mob. Nws raug nquahu kom ua qhov no tom qab li 8 ... 10 txhiab kilometers. Nws yog qhov yooj yim heev los ua qhov no thaum lub sijhawm hloov cov roj hauv lub tshuab hluav taws xob sab hauv. Txawm li cas los xij, nrog qhov pib ntawm cov tsos mob tau piav qhia saum toj no, nws tuaj yeem ua tiav ua ntej.

Nws tsim nyog hais tam sim ntawd tias txoj kev qub siv cov ntawv xuab zeb los ntxuav cov electrodes yuav tsum tau siv Tsis pom zoo. Qhov tseeb yog tias txoj kev no muaj kev pheej hmoo ntawm kev puas tsuaj rau cov txheej tiv thaiv ntawm lawv. Qhov no yog qhov tseeb tshwj xeeb rau iridium tswm ciab. Lawv muaj ib tug nyias nruab nrab electrode coated nrog iridium, ib tug semiprecious thiab tsis tshua muaj hlau.

Txhawm rau ntxuav lub txim taws koj yuav xav tau:

• detergent rau tshem tawm cov plaque thiab xeb;
• cov khob yas pov tseg (tom qab qhov kawg ntawm cov txheej txheem ntxuav, lawv yuav tsum muab pov tseg, lawv tsis tuaj yeem siv rau cov khoom noj khoom haus yav tom ntej);
• ib tug nyias txhuam nrog ib tug nyuaj pawg los yog ib tug txhuam hniav;
• khaub ncaws.

Cov txheej txheem ntxuav yog ua raws li hauv qab no algorithm:

Cov txheej txheem kev ua kom huv

1. Ib tus neeg sawv cev tu tau hliv rau hauv lub khob npaj ua ntej mus rau qib kom ua tiav lub ntsej muag lub ntsej muag (tsis muaj insulator) rau hauv.
2. Muab cov tswm ciab tso rau hauv ib lub khob thiab tawm rau 30 ... 40 feeb (nyob rau hauv cov txheej txheem, tshuaj ntxuav cov tshuaj tiv thaiv tshwm sim, uas tuaj yeem pom ntawm qhov muag liab qab).
3. Tom qab lub sijhawm teev tseg, cov tswm ciab raug tshem tawm ntawm lub khob, thiab nrog txhuam los yog txhuam hniav, cov quav hniav raug tshem tawm ntawm qhov chaw ntawm lub tswm ciab, tshwj xeeb tshaj yog them nyiaj rau cov electrodes.
4. Yaug cov tswm ciab hauv dej sov, tshem tawm cov tshuaj muaj pes tsawg leeg thiab cov av ntawm lawv qhov chaw.
5. Tom qab ntxuav, so cov tswm ciab qhuav nrog ib daim ntaub qhwv ua ntej.
6. Cov theem kawg yog kom qhuav cov tswm ciab ntawm lub tshuab hluav taws xob, hauv qhov cub (ntawm qhov kub ntawm +60 ... + 70 ° C) lossis nrog lub tshuab ziab khaub ncaws lossis kiv cua sov (qhov tseem ceeb tshaj plaws yog cov dej seem hauv lawv. tag nrho evaporates).

Cov txheej txheem yuav tsum tau ua tib zoo, ntxuav thiab tshem tawm tag nrho cov av thiab cov quav hniav uas muaj nyob rau saum npoo. nco, tias ntxuav thiab ntxuav tswm ciab ua haujlwm 10-15% zoo dua li cov qias neeg.

Cov txiaj ntsim tau los

Qhov tshwm sim ntawm lub txim taws dub ntawm lub carburetor lossis injector tuaj yeem tshwm sim los ntawm ntau yam laj thawj. feem ntau ob peb ntawm lawv. Piv txwv li, xaiv tswm ciab tsis raug, kev ua haujlwm ntev ntawm lub tshuab hluav taws xob sab hauv ntawm kev kub ceev, teeb tsis raug teeb meem, faulty valve qia ntsaws ruaj ruaj, thiab lwm yam. Yog li, peb xav kom koj, thaum cov tsos mob tau piav qhia saum toj no tshwm sim, tsuas yog tshawb xyuas qhov xwm txheej ntawm cov pob hluav taws xob ntawm koj lub tsheb.

Tshawb xyuas thiab ntxuav cov tswm ciab ntawm txhua qhov kev hloov roj (8 - 10 txhiab km). Nws yog ib qho tseem ceeb uas qhov sib txawv raug teeb tsa, thiab lub txim hluav taws xob insulator yog huv si. Nws raug pom zoo kom hloov tswm ciab txhua 40 ... 50 txhiab kilometers (platinum thiab iridium - tom qab 80 ... 90 txhiab).

Yog li koj yuav tsis tau tsuas yog ncua lub neej ntawm lub internal combustion engine, tab sis kuj tswj lub hwj chim thiab kev nplij siab tsav tsheb. Koj tuaj yeem pom cov ntaub ntawv ntxiv txog kev kuaj xyuas lub tsheb sab hauv lub tshuab hluav taws xob los ntawm cov xim ntawm cov kua nplaum ntawm cov hluav taws xob.
