Yuav Ua Li Cas Ntsuas CDI Box nrog Multimeter (Peb Kauj Ruam Qhia)
Txheem
CDI txhais tau hais tias capacitor tawm ignition. Lub CDI coil ua rau kis las lub thawv dub lub hau ntim nrog cov capacitors thiab lwm yam hluav taws xob circuits. Qhov hluav taws xob hluav taws xob hluav taws xob no feem ntau yog siv rau hauv lub tshuab hluav taws xob sab nraud, tshuab txiav nyom, maus taus, scooters, chainsaws thiab lwm yam khoom siv hluav taws xob. Capacitor tso tawm ignition yog tsim los kov yeej cov teeb meem cuam tshuam nrog lub sijhawm them nyiaj ntev.
Feem ntau, txhawm rau txheeb xyuas CDI lub thawv nrog lub ntsuas ntsuas, koj yuav tsum: Khaws lub CDI tseem txuas nrog lub stator. Ntsuas siv qhov kawg stator es tsis txhob CDI kawg. Ntsuas xiav thiab dawb kuj; Nws yuav tsum nyob nruab nrab ntawm 77-85 ohms thiab cov xaim dawb rau hauv av yuav tsum nyob nruab nrab ntawm 360-490 ohms.
Internal CDI Operations
Ua ntej peb kawm txog ntau txoj hauv kev los sim CDI lub thawv, tej zaum koj yuav xav paub txog kev ua haujlwm sab hauv ntawm koj qhov hluav taws xob CDI. Kuj tseem hu ua thyristor ignition, CDI khaws cov nqi hluav taws xob thiab muab pov tseg los ntawm lub thawv hluav taws xob kom nws yooj yim dua rau lub txim hluav taws xob hauv lub cav roj av los tsim lub txim muaj zog.
Tus nqi ntawm lub capacitor yog lub luag haujlwm rau kev muab ignition. Qhov no txhais tau hais tias lub luag haujlwm ntawm lub capacitor yog kom them thiab tso tawm thaum lub sijhawm kawg, tsim cov sparks. CDI ignition systems ua kom lub cav khiav kom ntev li ntev tau raws li qhov hluav taws xob tau them. (1)
Cov tsos mob ntawm CDI malfunction
- Cav misfiring tuaj yeem raug liam rau ntau yam. Ib lub thawv ignition hnav nyob rau hauv koj lub CDI module yog ib qho ntawm feem ntau ua rau lub cav misfiring.
- Lub tog raj kheej tuag tuaj yeem tiv thaiv cov hluav taws xob los ntawm kev tua kom raug. Fuzzy voltage signals tej zaum yuav yog vim qhov tsis zoo thaiv / pem hauv ntej diode. Yog tias koj muaj qee lub tog raj kheej tuag koj tuaj yeem tshawb xyuas koj CDI.
- Kev ua tsis tiav tshwm sim ntawm RMPS 3000 thiab siab dua. Thaum qhov no tuaj yeem qhia qhov teeb meem stator, kev paub tau pom tias CDI tsis zoo tuaj yeem ua rau muaj teeb meem tib yam.
Tam sim no cia peb kawm yuav ua li cas khij lub CDI lub thawv nrog lub multimeter.
Koj yuav xav tau ib lub thawv CDI thiab multimeter nrog tus pin coj. Nov yog XNUMX kauj ruam qhia rau kev sim CDI lub thawv.
1. Tshem tawm CDI chav tsev ntawm lub tshuab hluav taws xob.
Cia peb hais tias koj tab tom ua haujlwm ntawm koj lub maus taus CDI chav tsev.
Koj lub maus taus lub CDI chav tsev tsis muaj qhov tsis ntseeg txuas nrog cov xov hlau insulated thiab tus pin headers. Nrog rau qhov kev paub no, tshem CDI chav tsev ntawm lub maus taus, chainsaw, nyom mower lossis lwm yam khoom siv hluav taws xob uas koj ua haujlwm nrog tsis yog qhov nyuaj.
Thaum koj tau tswj kom tshem tawm nws, tsis txhob ua haujlwm tam sim ntawd. Cia nws nyob ib leeg li 30-60 feeb kom tso cai rau lub tank sab hauv kom tso cov nqi. Ua ntej kuaj koj lub CDI system nrog ib tug multimeter, nws yog qhov zoo tshaj los ua ib qho kev kuaj pom. Them mloog mus rau txhua yam deformations, uas manifest lawv tus kheej raws li kev puas tsuaj rau lub casing rwb thaiv tsev los yog overheating. (2)
2. Kev ntsuas CDI nrog lub ntsuas ntsuas - txias ntsuas
Txoj kev ntsuas txias yog tsim los ntsuas qhov txuas ntxiv ntawm CDI system. Koj lub multimeter yuav tsum nyob rau hauv kev txuas mus ntxiv ua ntej koj pib qhov ntsuas txias.
Tom qab ntawd coj cov thawj coj ntawm lub multimeter thiab txuas lawv ua ke. DMM yuav beep.
Lub hom phiaj yog los tsim kom muaj qhov muaj / tsis muaj qhov txuas ntxiv ntawm txhua qhov hauv av thiab ntau lwm cov ntsiab lus.
Txiav txim siab yog tias koj hnov ib lub suab. Yog tias koj chav CDI ua haujlwm zoo, koj yuav tsum tsis txhob hnov qab. Lub xub ntiag ntawm beeps txhais tau tias koj CDI module yog faulty.
Lub xub ntiag ntawm kev txuas ntxiv ntawm hauv av thiab lwm yam davhlau ya nyob twg txhais tau tias tsis ua haujlwm ntawm trinistor, diode lossis capacitor. Txawm li cas los xij, tsis yog txhua yam ploj. Hu rau tus kws tshaj lij los pab koj kho qhov ua tsis tiav.
3. Kev ntsuam xyuas CDI Box nrog multimeter - kub ntsuas
Yog tias koj xaiv siv txoj kev ntsuas kub, koj tsis tas yuav tshem CDI chav nyob ntawm stator. Koj tuaj yeem sim nrog CDI tseem txuas nrog stator. Qhov no yooj yim dua thiab sai dua li txoj kev ntsuas txias uas koj yuav tsum tshem tawm lub thawv CDI.
Cov kws tshaj lij pom zoo kom ntsuas qhov txuas ntxiv nrog lub multimeter los ntawm qhov kawg ntawm stator, tsis yog qhov kawg ntawm CDI. Nws tsis yooj yim rau kev txuas ib qho kev xeem coj los ntawm lub thawv CDI txuas.
Qhov xwm zoo yog tias qhov txuas ntxiv, qhov hluav taws xob thiab qhov tsis kam yog tib yam li qhov kawg ntawm stator.
Thaum ua qhov ntsuas kub, koj yuav tsum xyuas cov hauv qab no;
- Kev tiv thaiv ntawm xiav thiab dawb yuav tsum nyob rau hauv thaj tsam ntawm 77-85 ohms.
- Cov hlau dawb rau hauv av yuav tsum muaj qhov ua haujlwm ntawm 360 txog 490 ohms.
Thaum ntsuas qhov tsis kam ntawm cov xov hlau xiav thiab dawb, nco ntsoov teem koj lub multimeter rau 2k ohms.
Koj yuav tsum muaj kev txhawj xeeb yog tias koj cov txiaj ntsig kev tawm tsam tsis nyob hauv cov kab no, nyob rau hauv rooj plaub twg teem sijhawm nrog koj tus kws kho tsheb.
Lub multimeter yog ib qho cuab yeej siv tau zoo rau kev nkag mus thiab kuaj xyuas kev noj qab haus huv ntawm CDI lub thawv. Yog tias koj tsis paub siv multimeter, koj tuaj yeem kawm ib txwm. Nws tsis yooj yim thiab leej twg tuaj yeem siv nws los ntsuas qhov kev tiv thaiv thiab lwm yam tsis tau tsim los ntsuas. Koj tuaj yeem tshawb xyuas peb tshooj lus qhia kom paub ntau ntxiv multimeter tutorials.
Kev lees paub tias CDI chav ua haujlwm zoo yog qhov tseem ceeb rau kev ua haujlwm ntawm koj lub maus taus lossis lwm yam khoom siv hluav taws xob. Raws li ua ntej, CDI tswj cov roj injectors thiab lub txim hluav taws xob thiab yog li ntawd yog ib qho tseem ceeb hauv kev ua haujlwm zoo ntawm koj cov khoom siv hluav taws xob.
Qee qhov ua rau CDI tsis ua haujlwm yog kev laus thiab kev them nyiaj tsis raug.
Kev ruaj ntseg
Ua haujlwm nrog CDI systems yuav tsum tsis txhob maj maj, tshwj xeeb tshaj yog tias koj tsis paub txog qhov phem CDI. Cov khoom siv kho tshuab ntawm lub maus taus thiab lwm yam khoom siv yuav tsum tau ua tib zoo saib xyuas.
Siv cov cuab yeej tiv thaiv tus kheej xws li cov hnab looj tes tiv thaiv thiab cov hnab looj tes tiv thaiv dej. Koj tsis xav cuam tshuam nrog hluav taws xob raug mob vim tsis ua raws li kev ceev faj txog kev nyab xeeb.
Txawm hais tias lub peev xwm thiab cov khoom nquag hauv CDI lub thawv yog tsawg, koj tseem yuav tsum tau ceev faj.
Summing txog
Qhov saum toj no ob txoj hauv kev rau kev sim CDI blocks yog qhov ua tau zoo thiab siv tau. Txawm hais tias lawv txawv txawm nyob rau hauv cov nqe lus ntawm lub sij hawm siv (tshwj xeeb vim hais tias ib txoj kev yuav tsum tau tshem tawm ntawm lub CDI lub thawv), koj muaj peev xwm xaiv ib qho yooj yim tshaj rau koj.
Tsis tas li ntawd, koj yuav tsum txheeb xyuas qhov tshwm sim, vim tias qhov koj ua tom ntej yog nyob ntawm koj qhov kev tshuaj ntsuam. Yog tias koj ua yuam kev, piv txwv li, yog tias koj tsis tuaj yeem paub txog qhov teeb meem uas twb muaj lawm, qhov teeb meem yuav tsis daws sai.
Kev ncua kev kho kom tsim nyog tuaj yeem ua rau muaj kev puas tsuaj ntxiv rau koj qhov DCI thiab cov khoom muaj feem cuam tshuam thiab feem ntau ua rau koj qhov kev paub nrog koj lub maus taus, nyom mower, scooter, thiab lwm yam. Yog li, xyuas kom koj tau txais txoj cai no. Tsis txhob maj. Tsis txhob maj!
