TDC / crankshaft sensor
Txheem
Nws yog hu ua TDC lossis crankshaft sensor (nyob ib sab ntawm lub cav flywheel), nws ceeb toom rau ECU txog lub xeev ntawm lub cav kom nws thiaj li paub thaum twg (thiab ntau npaum li cas) roj yuav tsum tau txhaj. Yog li ntawd, thaum animating ob peb lub tog raj kheej, nws yog ib qho tsim nyog los tswj cov injectors kom lawv ua haujlwm raws sijhawm. Ntawm lub cav roj av, nws kuj tseem qhia rau koj paub thaum lub txim hluav taws xob tsim los ntawm lub txim hluav taws xob (tswj ignition).
Kev xav thiab kev ua haujlwm
Txawm hais tias hom TDC / crankshaft sensor (inductive lossis Hall effect), cov haujlwm tseem tshuav ntau dua lossis tsawg dua. Lub hom phiaj yog los ua ib qho cim ntawm lub cav flywheel kom qhia lub computer txoj hauj lwm ntawm tag nrho cov pistons uas ua rau lub cav. Txhua lub sij hawm lub sensor pom ib lub cim, cov ntaub ntawv raug xa mus rau lub computer, uas tom qab ntawd ua rau kev txhaj tshuaj ua raws li.
Txhua tus hniav hla mus rau pem hauv ntej ntawm lub sensor yuav ua rau muaj hluav taws xob me me (inductive sensors tau nce ntxiv los ntawm Hall effect versions). Ua tsaug rau qhov no, lub khoos phis tawj tuaj yeem suav tus lej ntawm cov hniav hla los ntawm nws thiab, yog li ntawd, ua raws li lub suab ntawm lub cev muaj zog. Tom qab ntxiv cov ntaub ntawv no rau lub cim, nws paub qhov ceev thiab txoj hauj lwm ntawm tag nrho cov pistons. Piv txwv li, hauv daim duab saum toj no, nws yuav paub qhov twg TDC ntawm lub tog raj kheej 1 thiab 4 yog, txij li nws tau preprogrammed ua 14 hniav tom qab lub cim. Yeej, lub laij lej kwv yees txhua yam ntxiv, tso siab rau ob peb cov ntaub ntawv muab rau nws. Txawm li cas los xij, thaum pib, cov khoom siv hluav taws xob yuav xav tau lub camshaft sensor kom paub yog tias TDC ntawm lub piston yog compression los yog tso tawm ... Thaum kawg, nco ntsoov tias qhov notch tsis tas yuav tsawg dua cov hniav, qee zaum pom ntawm flywheel disc. nrog lub sensor txuas tom qab nws (ntawm lub cav thaiv).
Tom qab ntawd, lub hauv paus ntsiab lus ntawm electromagnetism yog siv: hlau cav flywheel nrog cov hniav (nws muaj cov hniav tsim rau lub oob khab) cuam tshuam cov hlau nplaum ntawm lub sensor, uas ces xa pulses mus rau lub computer (rau txhua tus hniav hla). Thaum qhov sib txawv ntawm ob lub pulses ua ntau dua, lub computer paub tias nws yog nyob rau theem ntawm cov cim (qhov chaw uas cov hniav ploj lawm).
Lub khoos phis tawj tau txais hom nkhaus no (qhov txawv ntawm Hall effect versions, qhov nkhaus yog square thiab qhov sib txawv me me tsis muaj lawm) thiab yog li tuaj yeem txiav txim siab thaum twg thiab qhov twg txhaj roj (tab sis kuj ua rau muaj kev tswj hwm hluav taws xob ntawm cov essences)
Nov yog qhov nkhaus tiag tiag. Lub xiav yog TDC / crankshaft sensor thiab liab yog lub camshaft txoj hauj lwm sensor.
Yog tias lub flywheel tau ua los ntawm ntoo (piv txwv li ...), nws yuav tsis ua haujlwm, vim tias cov khoom siv no tsis tuaj yeem cuam tshuam cov electromagnetic teb.
Ntau hom
- Passive nrog inductive system : Tsis xav tau lub hwj chim mov, qhov txav ntawm lub flywheel nyob ib sab ntawm nws induces ib tug me me alternating tam sim no. Cov dataset materializes raws li ib tug sinusoidal teeb liab uas hloov nyob rau hauv zaus thiab amplitude (qhov siab thiab dav) nyob ntawm seb lub cev muaj zog ceev (ceev). Hom sensor no yog rhiab heev rau stray electromagnetic teb (los ntawm sab nraud), tab sis pheej yig dua los tsim. Nws yog kev puas tsuaj.
- Dhia nquag Hall nyhuv : Cov khoom siv hluav taws xob xav tau. Rau txhua tus hla flywheel hniav, nws xa 5 volt teeb liab mus rau lub computer. Qhov no tsis yog sine nkhaus, tab sis ib lub voj voog square uas zoo li tus lej binary. Nws muaj ib daim npav hluav taws xob me me uas muab kev sib tham ua lus tib yam li lub computer. Ntawm no, tam sim no ntws tsis tu ncua hauv lub sensor: thaum tus hniav hla ib sab (qhov kev ncua deb ntawm tus hniav thiab lub sensor yog hu ua qhov sib txawv ntawm huab cua), nws me ntsis cuam tshuam qhov tam sim no dhau los ntawm nws. Yog li ntawd, peb tuaj yeem suav cov hniav thiab qhia rau lub computer. Hom sensor no kim dua, tab sis sawv cev rau cov kauj ruam tom ntej hauv cov txheej txheem inductive qub vim nws yog qhov tseeb dua, tshwj xeeb tshaj yog nyob rau qis qis.
PMH HS cov tsos mob
Ntawm cov tsos mob tshwm sim feem ntau, peb nco txog qhov pib nyuaj, lub cav rattling (ib lub sensor uas ua haujlwm tsis tu ncua) lossis tsis muaj sijhawm thaum tsav tsheb ... Lub tachometer faulty kuj tuaj yeem yog lub cim ntawm qhov tsis ua haujlwm crankshaft sensor.
Qee lub sij hawm nws tsuas yog kev sib txuas uas pib corrode me ntsis, ces tsuas yog fiddling nrog lub sensor tuaj yeem rov qab tau qhov kev sib txuas. Txawm li cas los xij, nws yog qhov zoo tshaj los ntxuav cov connectors.
Qhov sib txawv ntawm huab cua (qhov sib txawv ntawm lub sensor thiab flywheel) tuaj yeem hloov me ntsis, vim tias lub sensor tsis raug txiav txim siab txoj haujlwm ntawm crankshaft.
Qhov txawv nrog camshaft sensor / lub tog raj kheej siv?
Lub tog raj kheej siv sensor tso cai, ntxiv rau TDC sensor, kom paub seb qhov twg theem twg txhua lub tog raj kheej yog, piv txwv li, nyob rau hauv lub compression theem (qhov twg nws yuav tsim nyog los tsim cov tshuaj thiab ignition rau roj av cav) los yog pa (tsis muaj dab tsi. ua, cia li cia cov pa tawm los ntawm cov pa tawm li qub). Yog li ntawd, thaum lub cav tsis muaj roj twj tso kua mis (lub twj tso kua mis distribution), nws yog ib qho tsim nyog yuav tsum tau qhia rau lub khoos phis tawj uas theem txhua lub piston nyob hauv, thiab yog li yuav tsum muaj AAC sensor. Xav paub ntau ntxiv ntawm no.
