Yog vim li cas yog lub engine chaw thaum idling: ua thiab cov kev daws qhov teeb meem

Tej self-saib lub tsheb tswv yuav tsum xyuas kom meej lub serviceability ntawm lub tsheb thiab ua rau nws nyob rau hauv zoo mob. Tab sis tej zaum muaj teeb meem nrog lub community launch thiab cov lag luam ntawm lub hwj chim unit. Piv txwv li, lub cav tsis idling. Yuav ua li cas yog qhov ua rau ntawm no tshwm sim, yuav ua li cas sib ntaus sib tua nws? Tag nrho cov no yuav tsum tau tham nyob rau hauv peb tsab xov xwm no niaj hnub no. Ua ntej teb rau ib lo lus nug hais txog yog vim li cas lub tsheb chaw ntawm kaw, peb nco ntsoov tias tag nrho cov teeb meem yuav txheeb faults nrog mov cua-roj sib tov.

Yog hais tias qhov no yog qhov lub khanpuletauj ntawm lub cav tsheb?

Nyob rau cov laus lub tsheb nrog ib tug carburetor kom tsawg system nrog cov tsos mob xws tsawg feempua sibtsoo ua tsis siv neeg caj pas. Qhov no lub caij ntawm "cov dab dej ntxuav" los yog tsis zoo tom. Yog hais tias chaw ntawm kaw Vaz-2106, qhov teeb meem tej zaum yuav txuam nrog to ntawm lub tshuab nqus tsev hose nyob ze ntawm lub hauv paus ntawm lub carburetor. Peb yuav tsum tsis txhob cais teeb meem nyob rau hauv lub txias system. Yog hais tias lub tsheb chaw ntawm kaw, mus saib lub ntsuas sov thiab. Thaum ib tug faulty valve mechanism tsis pub tus cav mus sai sai sov mus txog kev khiav hauj lwm kub. Thaum lub sij hawm lub caij ntuj sov, lub tsheb feem ntau boils.

Paub meej ntawm lub kom tsawg system

Txij li thaum lub cav ua hauj lwm yuav tsum tau tsis tsuas roj av, tab sis kuj cov pa, nrog turnover teeb meem txog kev mus rau lub cua kom tsawg manifold. Tej teeb meem yog vim ib tug huab cua los nyob rau hauv ib qho chaw uas yog downstream ntawm lub taub lim. Raws li ib tug tshwm sim, lub sensor cua flow meter yog tsis muaj peev xwm tswj cov txheej txheem, thiab cov tsheb chaw ntawm idling.

Injector feem ntau nruab nrog DFID. Koj yuav tsum tsis tau txais nws cov xim. Feem ntau, cov sensor yog polluted los ntawm 100-150 txhiab kilometers. Nws yuav kho tsis tau - tsuas yog yuav tsum tau hloov. Yog no pheej yig, tab sis precisely vim hais tias ntawm nws, nyob rau hauv feem ntau tus neeg mob ua luam dej idling. Tsav chaw kuj vim lub roj injectors. Nws yog ib nqi mus xyuas tus txheej xwm ntawm lub injector. Yog hais tias nws yog daig, revolutions ntawm lub crankshaft yuav tsis ruaj tsis khov. txawv nqi ntawm lub combustible sib tov, li no malfunction ntawm lub internal combustion engine mus rau hauv lub combustion chamber.

cov ntxaij lim dej

Thaum khiav nyob rau hauv 10 txhiab kilometers yog tsim nyog los hloov cov cua lim. Nws yog situated nyob rau hauv ib lub hnab yas los yog hlau tsev nyob (cov kev txhaj tshuaj thiab carburetor xyaw, ntsig txog). Yog hais tias qhov no caij yog raws li nram no, raws li nyob rau hauv cov kev yees duab hauv qab no, nws yuav tsum tau hloov.

Tab sis tsis tau tsuas yog ntxuav cov huab cua nyob rau hauv lub system. Xyuam xim rau cov roj cov ntxaij lim dej. Nyob rau diesel xyaw, lawv yog hloov txhua txhua 15 txhiab kilometers. Raws li rau lub tsheb nrog roj xyaw, lawv yog serviced txhua txhua 50,000. Lub peev xwm ntawm cov ntsiab yog 10 microns. Yog hais tias koj siv ib tug tsawg-zoo roj av los yog diesel cav, lub lim internals sai sai daig. Inside yog ntxeem tau daim ntawv.

Nyob rau hauv lub xub ntiag ntawm loj nyiaj ntawm cov av caij yog tsis muaj peev xwm ntxuav lub roj ntau. Raws li ib tug tshwm sim, lub tsheb tsis tuav idling, stalling. Nws tsis txuag txawm lub fact tias cov twj tso kua mis ua hauj lwm nyob rau hauv kub siab. Thaum hnyav ncawv daig lim yuav tsum tau hloov urgently. hloov kuj pab raws li ib tug kos npe rau ntawm lub hwj chim losses thiab failures lub sij hawm.

Qhov txawv ntawm cov carburetor thiab injector cov ntxaij lim dej

Nws yog ib nqi sau cia hais tias lub theem siab nyob rau hauv lub kom tsawg ntawm cov systems no sib txawv. Nyob rau hauv txhaj tshuaj xyaw nws muaj ntau lub sij hawm ntau. Yog li ntawd, koj yuav tsum tau xyuas nrog rau cov neeg muag khoom zoo li cas cav koj muaj thaum yuav ib lub tshiab roj lim. Qhov no yog tshwj xeeb tshaj yog muaj tseeb ntawm lub tsheb, uas tau ntsia rau ntau hom kev tshuab (piv txwv li, cov laus thiab cov tshiab "kaum").

Thaum lub txhaj cav mov lim rau carburetor, nws tsuas yuav tsis hais ntxiv rau hauv lub siab. Tag nrho cov av tau txais mus rau hauv lub injector twj tso kua mis. Lawv txhaws, yog li lub engine chaw ntawm idling. Raws li rau cov huab cua lim, qhia rau lawv sib nrug heev yooj yim. Nyob rau hauv roj av xyaw, lawv muaj ib tug puag ncig puab.

"Nulevik"

Yog hais tias lub tshuab siv pes tsawg kuj lim uas muaj ntau muaj kuab paug nws yuav ua teeb meem nyob rau hauv lub lag luam ntawm lub engine. Tab sis cov nqi ntawm cov tu lub caij yog 7-10 zaug dua li ib txwm. Yog li ntawd, siv tshwj xeeb tshuaj txau rau tu. Lim yog ua txhua txhua 10 txhiab kilometers. Tom qab daim ntawv thov yuav tsum tau tos kom txog thaum nws yog absorbed, thiab rau 5 feeb ntxuav tawm "nulevik" dej. Ua ntej installation, kom huv si qhuav nws. Txwv tsis pub, thaum koj khiav lub tshuab muab surge.

twj

Yog hais tias lub tsheb chaw ntawm kaw, yog vim li cas tej zaum yuav pw nyob rau hauv lub tsawg-siab twj tso kua mis. Nyob rau txhaj tshuaj xyaw nws yog submerged thiab muab cia rau hauv cov roj tank. Nyob rau lub khanpuletauj ntawm lub cav tsheb tshuab active caij nyob nyias los ntawm lub tank thiab koom mus rau ib tug cov neeg kho tshuab hom. Xws li ib tug twj tso kua mis actuated los ntawm ib tug kov. Hais tias yog, nws tsim lub yuav tsum tau siab nyob rau hauv lub system. Tab sis yog hais tias tus roj kab yog daig, immersion thiab txhua yam twj yog tsis khiav hauj lwm rau tag nrho cov muaj peev xwm. Raws li ib tug tshwm sim, lub tsheb chaw ntawm idling.

Yog hais tias lub tshuab tsis pib, nws yog tsim nyog los saib lub hwj chim mus rau lub chav tsev. Saib cov fuses thiab relays. Yog hais tias txhaj tshuaj twj tso kua mis yog engine buzzes thaum koj tig qhov ignition qhov tseem ceeb, nws txhais tau tias nws yog tsis powered. Nyob rau neeg caij tsheb nws yog nyob rau hauv lub tsheb, txoj cai (nyob rau hauv lub neeg nrog caij rooj zaum). Yog hais tias qhov no yog qhov diesel powerplant, nws yog tsim nyog los xyuas cov kev kub siab roj twj tso kua mis. Thaum uas tsis muaj kub nws accumulates paraffin - diesel khov hais. Muaj teeb meem nrog cov lub cev muaj zog khiav, ceev yog feem ntau "ua luam dej." Yuav tsum tsis txhob raug tshem tawm, thiab txhua yam kev puas tsuaj. Tej zaum qhov faulty cam tsav.

electronics

Yog hais tias lub tsheb chaw ntawm kaw, nws yog tsim nyog los tshawb nrhiav qhov onboard computer. Thaum uas tsis tshwm sim nyob rau hauv lub cajmeem kev mixing. Vim li no, lub cev muaj zog pib malfunction. Qhov no tshwm sim thaum lub lwm yam hluav taws xob khoom siv (xws li huab cua txias). Tawm ntawm no qhov teeb meem - lub tshuab hluav taws xob tswj tsev reinsertion.

catalytic converters

Nrog ua tej qauv rau diesel tsheb pib rau nruab rau hauv lub thiaj li hu ua diesel particulate cov ntxaij lim dej, thiab nyob rau petrol - catalysts. Lawv yog tsim rau ib tug tej lub sij hawm ntawm lub lag luam (kwv yees li 150 txhiab km). Thaum lub sij hawm, cov tub ntxhais yog daig. Lub tsev tsis tau tsim ib txwm tso zis thiab tso roj purification.

Tawm ntawm no qhov teeb meem - lub hloov catalyst arrester thiab reinsertion ntawm lub tshuab hluav taws xob unit. Tab sis nyob rau tib lub sij hawm koj lub tsheb cov pa tso qauv yuav poob mus rau lub "Euro 1" qhov tseem ceeb. Nyob rau hauv lub European Union hauv lub lag luam los ntawm xws tsheb yog txwv tsis pub. Tab sis, yog hais tias koj tsav feem ntau nyob rau hauv lub CIS, nws yog ib lub pom cov tshuaj rau qhov teeb meem. Vim hais tias tus nqi ntawm cov tshiab catalyst thiab diesel particulate lim pib los ntawm 40 txhiab rubles.

lub Recirculation valve

Lub tshuab yuav pog laus ntawm idling vim faults EGR. «P1406» yuam kev yog tso tawm thaum lub computer mob ntawm qhov screen. Nws qhia hais tias cov valve yog "daig" nyob rau hauv lub qhib los yog kaw txoj hauj lwm. Lub tsheb chaw ntawm dawb thiab qhia tau hais tias ib tug muaj zog sib rau siab. Thaum lub sij hawm, qhov no cov quav hniav accumulates valve. Nws yog tsim nyog los muab rho lub tsev thiab ntxuav nws. Tab sis yog thaum koj reinstall cov tsos mob recur, tab sis yuav tsum hloov.

Tsis Siab Sensor

Qhov no mechanism ntsuas lub tshuab nqus tsev nyob rau hauv lub manifold yuav tau kho tus nqi ntawm pub sib tov. Puas yam khoom nkag rau hauv lub cav yuam kev lawm. ECU xav hais tias lub cav ua hauj lwm nyob rau hauv ib tug ntau tsawg los yog ntau dua load dua nws yeej yog. Yog li, cov kev tswj chav tsev tshem tawm ib qhov nqi ntawm cov roj. Lub tshuab pib Tub Ntsuag. Tawm qhov teeb meem - hloov tsis siab sensor. Yog li ntawd, peb pom tawm yog vim li cas vim li cas lub tsheb chaw ntawm idling.
