TSHEB KWJ Sensor Muaj Luag
Lub luag haujlwm tseem ceeb ntawm kev kho tsheb tshuab sensor yog txhawm rau txhawm rau txhawm rau txhawm rau tiv thaiv lub cav ignition, yog li tiv thaiv lub cav los ntawm kev puas tsuaj.
Lub khob lub zog hloov kho cov neeg kho tshuab vibrations ntawm lub cav rau hauv chav hluav taws xob uas tau xa mus rau chav tswj hluav taws xob (ECU). EPU hloov kho lub ignition ua ntej lub kaum sab xis raws li cov teeb liab kom tsis txhob muaj qhov tshwm sim tsis tu ncua. Lub khob cij sensor feem ntau siv cov khoom siv tshuab ceramicectric ceramic. Thaum lub cav shakes, cov ceramic tau comperteds thiab deformed los tsim lub cim hluav taws xob, uas kis tau rau ECU los ntawm cov ntaub thaiv cov hlau rau kev ua.
Tus txheej txheem ua hauj lwm ntawm lub khob cij sensor yog raws cov efficzoelectric kab, thaum lub cav cower, cov kab ke lub cav, tsim hluav taws xob. Cov phiajcim no tau xa mus rau ECU, uas hloov kho cov ignition ua ntej lub kaum ntse ntse raws li cov ntaub ntawv khaws cia kom tiv thaiv knocking. Tsis tas li ntawd, khob sensors tuaj yeem hnov qhov nrawm thiab txoj haujlwm ntawm lub cav, muab ntau cov ntaub ntawv los pab ua kom muaj kev ua kom ua kom zoo dua qub.
Lub khob cij sensor feem ntau yog nruab rau thaj chaw tshwj xeeb hauv lub cav thaiv, xws li ntawm 2 thiab 3 lub tog raj kheej ntawm 1 thiab 2 lossis 4 lub tog raj kheej. Nws txoj haujlwm mounting kom muaj kev nkag siab ntawm kev ntes me me lub cav me me cibrations thiab khob.
Yog hais tias lub khob sensor tsis ua tiav, txawm hais tias nws yuav tsis ua lub cav kom tsis pib, nws yuav ua teeb meem xws li lub cav Jitter, Kev lag luam hluav taws xob, thiab teeb lub teeb. Yog li ntawd, kev ua haujlwm kom tsim nyog ntawm lub khob cij sensor yog qhov tseem ceeb rau lub cav kev ua tau zoo.
Automotive hoob khob yog ib qho cuab yeej nruab rau lub cav thaiv, tsuas yog siv los tshawb xyuas lub cav ntawm lub cav. Muaj ntau hom fintors, feem ntau ntawm cov uas suav nrog Magnetostrictive thiab piezoelectric ceramic.
Hom thiab cov qauv ntawm lub khob sensor
Magnetostrictrictive: muaj cov hlau nplaum sib nqus, cov hlau nplaum tas mus li ntev ntev thiab kev sib tham ua ntu zus. Thaum lub cav vibrates, cov sib nqus tub ntxhais tub ntxhais ua ke txav, ua rau muaj kev hloov pauv hauv kev sib nqus flux hauv kev sib tw chev, uas ua rau muaj kev quab yuam electromotive.
Piezoelectric Ceramic: thaum lub cav co, cov khoom sib xyaw ua ke sab hauv yog squeeze kom tsim cov teeb hluav taws xob. Vim tias lub teeb liab tsis muaj zog, kev sib txuas cable feem ntau qhwv nrog cov ntaub thaiv hlau.
Piezoelectric resonance: ntsia rau ntawm sab qaum kev ntawm lub cav cav, kev siv cov nyhuv piezoelectric hloov kho tshuab hluav taws xob. Thaum lub KNOCK kev co zaus ua kom haum rau lub ntuj ci, Remonance Prenomenon yuav tshwm sim rau lub sijhawm hluav taws xob ntau, raws li cov ECU yuav hloov kho kom tsis txhob khob.
Yuav ua li cas ib tug pob sensor ua haujlwm
Lub khob sensor xav txog cov kev co thiab suab ntawm lub cav thiab hloov cov teeb liab uas tau xa mus rau chav tsim hluav taws xob (ECU). EPU hloov kho lub ignition ua ntej lub kaum sab xis raws li cov tau txais teeb liab los tiv thaiv qhov tshwm sim ntawm kev tawg. Cov ntsiab cai ua haujlwm tshwj xeeb yog raws li hauv qab no:
Magnetostrictive: Cav Kev Lom Zem Ua Rau Cov Tub Ntxhais Sib Nqus Kom Ua Haujlwm, Hloov Lub Sib Nqus Flux hauv Kev Sib Nqus Sib Nqus Hauv Kev Sib Nqus Coil, uas ua rau muaj kev quab yuam electromotive.
Piezoelectric Ceramic: Thaum lub cav shakes, lub teeb liab qab los tsim lub teeb liab hluav taws xob, EPU kho lub sijhawm ignition raws li lub teeb liab.
Piezoelectric Resonance Hom: Thaum lub zog kev co zaus: thaum muaj cov xwm txheej ntawm lub teeb, thiab cov khoom tshwm sim hauv lub ntuj muaj zog, thiab lub siab khob cov paib hluav taws xob yog tso tawm rau EPU.
Lub luag haujlwm ntawm kev ua lub ntsej muag hauv tsheb
Lub luag haujlwm tseem ceeb ntawm lub khob sensor yog los ntsuas cov jitter degree ntawm lub cav. Thaum lub cav tsim khob, lub teeb hluav taws xob tau kis mus rau ECU, thiab EPU kho cov ignition ua ntej lub kaum ntse ntse ua ntej los tiv thaiv kev txuas ntxiv mus. Khob tuaj yeem ua rau lub cav puas tsuaj, yog li rooj ua kom zoo, yog li qhov chaw ua haujlwm ua si lub luag haujlwm tseem ceeb hauv kev tiv thaiv lub cav.
