Siv cov theem sensor, nws tuaj yeem taug qab txoj haujlwm ntawm lub camshaft. Nws tsis yog ntsia rau hauv lub cav carburetor; lawv tsis yog thawj cov ntawv luam ntawm cov tshuab txhaj tshuaj. Tab sis nws tuaj yeem pom hauv yuav luag txhua lub cav nrog 16 li qub. Yim-valve engine yog nruab nrog cov khoom siv no tsuas yog tias lawv ua raws li Euro-3 cov qauv tshuaj lom neeg, muaj cov txheej txheem ua ntu zus los yog faib cov roj sib xyaw. Kev nthuav qhia loj ntawm cov khoom siv no pib nyob ib puag ncig xyoo 2004 rau cov cav tsim los ntawm VAZ.

Dab tsi yog qhov sensor rau?

Nrog kev pab los ntawm cov theem sensor ntawm "Kalina" nws tuaj yeem txiav txim siab lub voj voog ntawm lub cav thiab tsim cov teeb liab. Cov cuab yeej no yog ib qho tseem ceeb, nyob rau hauv lwm yam lus, nws muaj ib tug sensing tivthaiv thiab lub teeb liab converter. Qhov ua haujlwm ntawm lub sensor ua haujlwm ntawm Hall effect. Nws teb rau cov kev hloov pauv hauv qhov chaw sib nqus. Nyob rau hauv lub thib ob Circuit Court muaj ib tug choj Circuit Court, raws li zoo raws li ib tug tshwj xeeb ua hauj lwm amplifier thiab ib tug transistor theem. Thiab qhov tom kawg yog ua raws li cov txheej txheem qhib sau.

Siv cov theem sensor (VAZ-2114 lossis ntawm lwm tus qauv), lub sijhawm ntawm kev txhaj tshuaj roj tsuas yog xaiv hauv thawj lub tog raj kheej, thiab raws li qhov no, ntawm txhua lwm yam. Lub camshaft tso cai rau koj los txiav txim siab seb lub valve twg nyob rau hauv txoj haujlwm qhib thiab lub sijhawm twg ntawm kev ua haujlwm tau ua. Yog hais tias lub sensor malfunctions, ib tug yuam kev teeb nyob rau hauv lub on-board computer, thiab lub lag luam ntawm lub cav mus rau hauv kev kub ceev hom. Kev ua haujlwm tsuas yog ua tiav ntawm lub teeb liab uas los ntawm lub crankshaft txoj hauj lwm sensor.

Txoj kev txhaj tshuaj phased

Theem sensor ntawm lub cav "Kalina" thiab "Priora" yog nyob rau sab sauv. Nws nyob ib sab ntawm lub tsev lim cua. Kev ua haujlwm ntawm kev txhaj tshuaj phased yog tus cwj pwm los ntawm cov yam ntxwv hauv qab no: lub mem tes xa tawm los ntawm theem sensor mus rau lub tshuab hluav taws xob tswj qhov system. Lub tom kawg tswj cov khoom siv roj, raws li qhov tshwm sim ntawm lub nozzle qhib, thiab cov roj-cua sib tov nkag mus rau hauv combustion chamber ua ntej lub valve pib qhib. Thaum lub valve qhib, cua yog nqus rau hauv thiab cov roj sib tov nkag mus rau hauv lub combustion chamber.

Yuav ua li cas nkag siab tias lub sensor faulty?

Cov tsos mob hauv qab no yuav pab koj txheeb xyuas cov khoom siv tsis raug:

  1. Thaum sim pib lub cav, lub tshuab pib tigrau 3-4 vib nas this. Tsuas yog tom qab ntawd lub cav pib, tab sis qhov yuam kev teeb tuaj. Cov kab hauv qab yog tias thaum koj sim pib lub cav, lub sensor tau raug xaiv, tab sis lub tshuab hluav taws xob tswj tsis tau txais lub teeb liab thiab hloov mus ua haujlwm tsuas yog siv cov ntaub ntawv tau txais los ntawm tus nyeem ntawv hauv crankshaft.
  2. Roj nce ntxiv.
  3. Lub tsheb dynamics deterioration. Nco ntsoov kuaj mob, vim tias qhov ua tsis tau zoo kuj tseem nyob hauv huab cua huab cua ntws sensor.
  4. Failures tshwm sim thaum lub sij hawm tswj qhov kev kuaj tus kheej.

Tsim cov cuab yeej

Theem sensor ntawm "Priora" thiab lwm lub tsheb yog ib qho tseem ceeb ntawm kev ua haujlwm, uas suav nrog kev tau txais txhua yam ntaub ntawv hais txog lub voj voog ua haujlwm ntawm lub cav, nrog rau kev xa cov teeb liab mus rau chav tswj hluav taws xob siv. tshwj xeeb impulses. Tus tsim ntawm lub sensor muaj 2 qhov chaw.

Qhov no yog Hall effect sensing element thiab me me transducer. Cov ntsiab lus rhiab heev teb rau cov kev hloov pauv hauv cov hlau nplaum. Lub sensor yog nyob rau ntawm qhov kawg ntawm lub tog raj kheej thaiv, tsis deb ntawm lub lim cua. Muaj cov hlau disk ntawm lub camshaft uas tsim nyog rau lub sensor kom ua haujlwm zoo.

Sensor yuam kev

Yog tias muaj cov tsos mob ntawm kev ua haujlwm tsis zoo ntawm theem sensor, lub cav yuam kev icon teeb, nws raug nquahu kom kuaj xyuas qhov kev tswj hwm. Yog tias muaj lub khoos phis tawj on-board, tom qab ntawd koj tuaj yeem pom qhov yuam kev nrog tus lej 0343 lossis0340. Tab sis tsis txhob maj hloov tam sim ntawd, nws yog heev tau hais tias muaj kev puas tsuaj nyob rau hauv cov xov hlau uas nws txuas nrog lub computer. Feem ntau, lub sensor tsuas yog qias neeg, uas ua rau tsis muaj peev xwm nyeem cov ntaub ntawv. Tab sis nyob rau hauv cov ntaub ntawv uas, tom qab kuaj lub sensor, ib tug malfunction yog pom, nws yog tsim nyog los yuav ib tug tshiab thiab nruab. Tus nqi ntawm cov cuab yeej tsis ntau tshaj 600 rubles.

Yuav ua li cas txheeb xyuas cov sensors ntawm 16-valve engine?

Cov txheej txheem kuaj mob rau 16- thiab 8-valve xyaw yog kwv yees li qub.

txhawm rau txheeb xyuas qhov kev pabcuam, koj yuav tsum ua cov hauv qab no:

  1. Teem lub multimeter rau qhov ntsuas qhov ntsuas voltage. Qhov chaw pib tuaj yeem teeb tsa ntawm 20 V.
  2. Nws yog qhov tsim nyog los txuas qhov hluav taws xob tas li ntawm 13.5 Volts rau "E" hu.
  3. Tib lub sijhawm, yuav tsum muaj qhov hluav taws xob ntawm 0.4 Volts ntawm "B" tus pin.
  4. Nqa cov khoom siv hlau, xws li lub hau ntswj, mus rau qhov ua haujlwm ntawm theem sensor. Yog tias lub cuab yeej ua haujlwm, ces qhov hluav taws xob ntawm qhov tso zis "B" yuav nce mus rau 0.9 volts.
  5. Yog tias koj tshem cov khoom siv hlau los ntawm cov khoom nquag, qhov hluav taws xob ntawm tus pin "B" yuav rov qab mus rau nws txoj haujlwm qub.

Kev kuaj mob ntawm yim-valve engine

Thov nco ntsoov tias qhov ntsuas rau 8 thiab 16 lub tshuab hluav taws xob tsis hloov pauv tau. Yog li ntawd, thaum muas, xyuam xim rau qhov nuance. Txhawm rau ua qhov kev kuaj mob ntawm theem sensors, nws yog ib qho tsim nyog yuav tsum tau ua cov hauv qab no:

  1. Hu rau "E"Txuas qhov hluav taws xob tas li ntawm 13.5 volts.
  2. Tus "B" tus pin yuav tsum yog 0.9 V.
  3. Tom qab nqa cov khoom hlau mus rau qhov nquag ntawm lub cuab yeej, qhov voltage yuav txo qis rau 0.4 V.
  4. Yog tias koj tshem cov cuab yeej hlau, qhov hluav taws xob yuav rov qab mus rau tus nqi ntawm 0.9 V.

Instrument replacement

Nyob rau hauv qhov xwm txheej uas lub cuab yeej tawg, tsis muaj qhov taw qhia kho nws. Nws yog qhov yooj yim dua los hloov cov theem sensor, txij li koj yuav siv ob peb feeb rau qhov no. Rau kev kho, koj xav tau 10 lub qhov (socket) thiab ratchet. Cov txheej txheem yog raws li nram no:

  1. Disconnect lub davhlau ya nyob twg tsis zoo ntawm lub roj teeb.
  2. Unscrew lub ntsia liaj qhov rooj kho lub sensor ntawm lub cav thaiv thiab disconnect lub thaiv uas nws txuas nrog hluav taws xob.
  3. Txhua yam kev sib cuag ntawm qhov thaiv thiab nruab ib lub sensor tshiab.

Yog tias cov xaim ua haujlwm tau zoo thiab tsis muaj teeb meem thaum lub sijhawm teeb tsa, txhua qhov yuam kev ploj ntawm lub khoos phis tawj ntawm lub rooj tsavxwm. Lub cav ua haujlwm yuav nkag mus rau theem txhaj tshuaj.
