Ignition kauj.
Nrog rau txoj kev loj hlob ntawm lub tsheb roj av cav mus rau cov kev taw qhia ntawm kev kub ceev, siab compression piv, siab zog, tsis tshua muaj roj noj thiab emission tsawg, cov tsoos ignition ntaus ntawv tsis tau raws li qhov yuav tsum tau ntawm kev siv. Cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob yog cov hluav taws xob hluav taws xob thiab cov cuab yeej hloov pauv, txhim kho lub zog ntawm cov hluav taws xob hluav taws xob hluav taws xob, lub txim hluav taws xob tuaj yeem tsim cov hluav taws xob txaus, uas yog qhov tseem ceeb ntawm cov cuab yeej hluav taws xob kom hloov mus rau kev ua haujlwm ntawm cov tshuab niaj hnub. .
Feem ntau muaj ob txheej coils hauv lub ignition coil, thawj kauj thiab theem nrab kauj. Thawj kauj yog siv cov hlau enameled tuab, feem ntau yog li 0.5-1 hli enamelled hlau nyob ib ncig ntawm 200-500 lem; Cov coil thib ob siv cov hlau nyias nyias, feem ntau yog li 0.1 hli enamelled hlau nyob ib ncig ntawm 15000-25000 tig. Ib qho kawg ntawm thawj kauj yog txuas nrog lub tshuab hluav taws xob qis (+) ntawm lub tsheb, thiab lwm qhov kawg yog txuas nrog lub tshuab hloov pauv (breaker). Ib qho kawg ntawm ob lub kauj yog txuas nrog lub hauv paus kauj, thiab lwm qhov kawg yog txuas nrog cov zis kawg ntawm cov kab hluav taws xob siab kom tso tawm qhov hluav taws xob siab.
Yog vim li cas vim li cas qhov hluav taws xob hluav taws xob tuaj yeem tig qhov hluav taws xob qis mus rau qhov hluav taws xob siab ntawm lub tsheb yog tias nws muaj tib daim ntawv zoo li lub tshuab hluav taws xob zoo tib yam, thiab cov kauj ruam tseem ceeb muaj qhov sib piv loj dua li cov kauj ruam thib ob. Tab sis lub ignition coil ua hauj lwm hom yog txawv los ntawm cov zoo tib yam transformer, lub zoo tib yam transformer ua hauj lwm zaus yog tsau 50Hz, los yog lub hwj chim zaus transformer, thiab lub ignition kauj yog nyob rau hauv daim ntawv ntawm mem tes ua hauj lwm, yuav suav hais tias yog ib tug pulse transformer, nws. raws li qhov sib txawv ceev ntawm lub cav ntawm ntau zaus ntawm kev rov ua lub zog cia thiab tawm.
Thaum lub hauv paus kauj yog powered on, ib tug muaj zog magnetic teb yog generated nyob ib ncig ntawm nws raws li qhov tam sim no nce, thiab lub magnetic teb zog yog khaws cia nyob rau hauv lub hlau core. Thaum lub tshuab hloov pauv disconnects thawj kauj Circuit Court, lub magnetic teb ntawm thawj coil decays sai, thiab theem nrab coil senses ib tug high voltage. Qhov nrawm dua qhov sib nqus ntawm cov kauj ruam tseem ceeb ploj, qhov ntau dua qhov tam sim no ntawm kev sib txuas tam sim no, thiab ntau dua qhov sib npaug ntawm ob lub kauj, qhov siab dua qhov voltage induced los ntawm lub kauj thib ob.
Coil hom
Ignition kauj raws li qhov sib nqus Circuit Court yog muab faib ua hom sib nqus qhib thiab kaw sib nqus hom ob. Cov kab hluav taws xob ib txwm muaj yog hom qhib sib nqus, thiab nws cov tub ntxhais hlau yog stacked nrog 0.3mm silicon steel nplooj ntawv, thiab muaj cov theem nrab thiab thawj coils nyob ib ncig ntawm cov tub ntxhais hlau. Lub kaw sib nqus hom siv cov tub ntxhais hlau zoo ib yam li Ⅲ nyob ib ncig ntawm lub hauv paus kauj, thiab tom qab ntawd cua tshuab thib ob sab nraud, thiab cov kab hlau nplaum yog tsim los ntawm cov tub ntxhais hlau. Qhov zoo ntawm qhov kaw sib nqus hluav taws xob hluav taws xob yog qhov sib nqus tsis tshua muaj hluav taws xob, lub zog me me poob thiab me me, yog li cov hluav taws xob hluav taws xob hluav taws xob feem ntau siv kaw qhov sib nqus hluav taws xob hluav taws xob.
Numerical tswj ignition
Nyob rau hauv lub high-ceev roj av cav ntawm niaj hnub tsheb, ignition system tswj los ntawm microprocessor, tseem hu ua digital electronic ignition system, tau saws. Lub ignition system muaj peb ntu: microcomputer (lub computer), ntau yam sensors thiab ignition actuators.
Qhov tseeb, nyob rau hauv niaj hnub xyaw, ob qho tib si roj av txhaj tshuaj thiab ignition subsystems yog tswj los ntawm tib ECU, uas sib koom ib txheej ntawm sensors. Lub sensor yog tib yam li lub sensor nyob rau hauv lub tshuab hluav taws xob tswj roj av, xws li crankshaft txoj hauj lwm sensor, camshaft txoj hauj lwm sensor, throttle txoj hauj lwm sensor, intake manifold siab sensor, dedetonation sensor, thiab lwm yam. Ntawm lawv, dedetonation sensor yog ib tug heev tseem ceeb sensor mob siab rau hluav taws xob tswj hluav taws xob hluav taws xob (tshwj xeeb tshaj yog lub cav nrog cov pa roj turbocharging ntaus ntawv), uas tuaj yeem saib xyuas seb lub cav dedetonation thiab qib ntawm dedetonation, raws li cov lus qhia tawm tswv yim los ua ECU cov lus txib kom ua tiav ignition ua ntej, kom lub cav yuav tsis dedetonation thiab tuaj yeem tau txais kev ua kom zoo dua combustion.
Cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob (ESA) tau muab faib ua ob hom raws li nws cov qauv: distributor type thiab non-distributor type (DLI). Lub distributor hom hluav taws xob hluav taws xob hluav taws xob siv tsuas yog ib qho hluav taws xob hluav taws xob los ua kom muaj hluav taws xob siab, thiab tom qab ntawd tus distributor ignites lub txim plug ntawm txhua lub tog raj kheej nyob rau hauv lem raws li lub ignition theem. Txij li thaum lub tshuab hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob tau ua los ntawm cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob, tus distributor tau tso tseg cov khoom siv hluav taws xob thiab tsuas yog ua lub luag haujlwm ntawm high-voltage tis.
Ob lub tog raj kheej ignition
Ob-lub tog raj kheej ignition txhais tau hais tias ob lub tog raj kheej sib koom ib qho ignition coil, yog li hom ignition no tsuas yog siv rau ntawm cov cav nrog ib tus naj npawb ntawm lub tog raj kheej. Yog tias ntawm lub tshuab 4-lub tog raj kheej, thaum ob lub tog raj kheej pistons nyob ze rau TDC tib lub sijhawm (ib qho yog compression thiab lwm qhov yog tso tawm), ob lub qhov hluav taws xob sib faib tib lub ignition coil thiab ignite tib lub sijhawm, ces ib qho zoo. ignition thiab lwm yam yog ineffective ignition, lub qub yog nyob rau hauv lub sib tov ntawm high pressure thiab tsis kub, lub tom kawg yog nyob rau hauv lub tso pa roj ntawm tsis tshua muaj siab thiab kub. Yog li ntawd, qhov kev tawm tsam ntawm cov hluav taws xob hluav taws xob ntawm ob qhov sib txawv kiag li, thiab lub zog tsim tawm tsis zoo ib yam, ua rau lub zog loj dua rau kev siv hluav taws xob zoo, suav txog li 80% ntawm tag nrho lub zog.
Cais hluav taws xob
Txoj kev sib cais ntawm qhov hluav taws xob faib cov hluav taws xob hluav taws xob rau txhua lub tog raj kheej, thiab cov hluav taws xob hluav taws xob tau nruab ncaj qha rau saum lub qhov hluav taws xob, uas tseem tshem tawm cov hlau hluav taws xob siab. Hom kev sib tsoo no yog ua tiav los ntawm camshaft sensor lossis los ntawm kev saib xyuas lub tog raj kheej compression kom ua tiav qhov hluav taws xob raug, nws tsim nyog rau txhua lub tog raj kheej cav, tshwj xeeb tshaj yog rau cov cav nrog 4 li qub rau ib lub tog raj kheej. Vim tias qhov hluav taws xob hluav taws xob hluav taws xob sib txuas ua ke tuaj yeem txuas rau hauv nruab nrab ntawm ob lub taub hau camshaft (DOHC), qhov sib txawv yog siv tag nrho. Vim tias qhov kev tshem tawm ntawm cov khoom siv hluav taws xob thiab cov kab hluav taws xob siab, lub zog hluav taws xob tsis zoo thiab cov xau poob yog qhov tsawg, tsis muaj kev siv tshuab, thiab cov hluav taws xob hluav taws xob thiab cov hluav taws xob hluav taws xob ntawm txhua lub tog raj kheej tau sib sau ua ke, thiab cov pob hlau sab nraud zoo heev txo cov khoom siv hluav taws xob. electromagnetic cuam tshuam, uas tuaj yeem ua kom lub cev ua haujlwm ntawm lub cav hluav taws xob tswj qhov system.
