Tom qab hloov kho Cov Cuab Yeej Siv Hluav Taws Xob Ntawm Kev Tawm - Kev Tsav Tsheb Tsav Tsheb (xws li Hloov Cov Cua Txias Tag Nrho), Nws Puas Yuav Tsum Tau Kho Cov Carburetor lossis Roj Txhaj?

Kev hloov kho cov pa tawm ntawm kev tawm - kev maus taus, xws li hloov tag nrho cov pa tawm, feem ntau yuav tsum tau kho cov carburetor lossis roj injectors. Txawm li cas los xij, seb yuav tsum tau hloov kho li cas thiab yuav tsum tau txiav txim siab raws li qhov kev ntsuam xyuas dav dav ntawm qhov kev hloov pauv ntawm cov pa hluav taws xob, lub tshuab ua haujlwm ntawm lub cav thiab cov qauv ntawm lub Hoobkas qub. Nov yog qee cov ntsiab lus:
Qhov cuam tshuam ntawm Exhaust System Modifications ntawm Engines ntawm lub cav
Lub luag haujlwm tseem ceeb ntawm kev tso pa tawm yog kom tso pa tawm thiab ua kom cov khoom noj kom zoo. Kev hloov ntawm tag nrho cov pa tso pa tawm (xws li cov yeeb nkab loj dua, siab -kev ua haujlwm silencers lossis pub dawb- ntws tawm) yuav hloov pauv cov yam ntxwv hauv qab no:
Txo Cov Cuab Yeej Cuab Yeej Cuab Yeej: Cov qauv tso tawm thawj zaug feem ntau tswj xyuas qee qhov backpressure kom sib npaug qis torque thiab lub zog siab. Tom qab kev hloov kho, lub tailpipe smoother thiab lub nraub qaum siab yog pom tseeb txo qis, uas yuav ua rau cov pa pa tawm sai heev thiab cuam tshuam rau cov pa roj seem hauv lub tog raj kheej, yog li hloov kev noj haus kom zoo.
Kev hloov pauv hauv Airflow Velocity: Cov kev hloov pauv ntawm cov yeeb nkab txoj kab uas hla, qhov ntev los yog muffler qauv tuaj yeem cuam tshuam rau cov pa tawm ntawm cov pa tawm. Piv txwv li, cov yeeb nkab loj loj tuaj yeem txo qhov nrawm ntawm cov cua tsis tshua muaj zog thiab tiv thaiv cov pa tawm (xws li "cov pa tsis txaus") los ntawm kev pub cov roj cua tshiab sib xyaw rau hauv lub tog raj kheej. Kub thiab Siab Tshaj Tawm: Kev hloov pauv hauv qhov kub thiab txias tuaj yeem cuam tshuam rau kev tswj xyuas lub cav thiab txawm tias qhov ntsuas ntsuas (xws li oxygen sensor), cuam tshuam tsis ncaj qha rau cov roj txhaj tshuaj lossis lub sijhawm hluav taws xob.
ii. Vim li cas koj thiaj li yuav tsum tau kho cov carburetor lossis roj injectors?
Cov huab cua- hluav taws xob piv (AFR) ntawm lub cav yuav tsum tau ua raws li qhov yuav tsum tau ua ntawm kev ua haujlwm ntawm cov pa, nqus, compression thiab ignition plaub-stroke. Yog tias lub carburetor lossis roj injectors tsis raug kho tom qab hloov kho qhov tso pa tawm, cov teeb meem hauv qab no yuav tshwm sim:
Lean Blend: Cov pa hluav taws xob qis qis tuaj yeem ua rau kom tau txais txiaj ntsig, tab sis yog tias cov roj txhaj tshuaj tsis hloov raws li qhov xav tau, huab cua - rau - huab cua combustion piv tuaj yeem siab dhau (sib tov sib xyaw). Cov tsos mob muaj xws li: txo hwj chim hauv siab RPMs launchers (vim tsis tiav combustion); overheating ntawm cov cav tov (vim kub combustion ntau); thiab siab - pitched inclination tso pa tawm (vim qhov kev sib txuas thib ob ntawm cov roj tsis tau hlawv hauv cov yeeb nkab tso).
Kev nplua nuj hybrids: Yog tias qhov kev hloov pauv ntawm qhov tso pa tawm tsis tau txhim kho kev noj qab haus huv zoo, tab sis cov carburetor lossis roj injectors tseem muab roj raws li lub Hoobkas tsis, huab cua - rau - roj piv yuav qis dhau (nplua nuj sib xyaw). Cov tsos mob muaj xws li: txo torque rau qis RPMs launchers (vim qeeb combustion); cov pa luam yeeb dub los ntawm cov yeeb nkab (vim tsis tiav roj combustion); thiab nce carbon buildup (vim roj residue).
Kev txwv tsis pub hloov ntawm ECUs lossis carburetor:
Carburetor tsheb: Carburetor kho cov roj los ntawm cov cuab yeej siv xws li lub ntsiab thiab tsis siv neeg injectors, tsis tuaj yeem hloov mus rau cov kev hloov pauv hauv cov pa thiab yuav tsum tau hloov kho phau ntawv.
Lub tsheb txhaj tshuaj hluav taws xob hauv hluav taws xob: Qee lub tshuab hluav taws xob siv hluav taws xob, xws li qhib- lub tshuab tswj lub voj voog, yuav tsis tuaj yeem hloov kho cov roj txhaj tshuaj sai sai raws li cov lus pom los ntawm cov pa oxygen sensor; ECU remapping lossis injector parameter hloov yog yuav tsum tau ua kom zoo dua huab cua - rau - roj piv.
III. Cov txheej txheem tshwj xeeb rau kev kho cov Carburetor lossis Injectors
1. Kev hloov cov kauj ruam rau cov tsheb carburetor
Kev hloov dav hlau loj: hloov lub ejector tseem ceeb nrog lub ejector loj lossis me me (piv txwv li, hloov ntawm # 140 mus rau # 145 kom muaj roj ntau ntxiv) raws li lub zog ua haujlwm ntawm cov pa hloov pauv.
Idle sib tov Screw: Kev sib hloov ntawm Idle Mixer Screw (feem ntau nyob rau hauv qab ntawm lub carburetor) kho qhov sib piv ntawm cov cua kub ntawm lub carburetor. Tightening clockwise txo cov roj mov thiab counterclockwise tightening nce roj mov. Lift: Tshawb xyuas thiab kho qhov siab ntab kom ntseeg tau tias cov roj qib ruaj khov thiab tiv thaiv cov roj ntau dhau vim muaj kev sib tw ntau dhau.
Kev hloov kho synchronization: Rau ob lub-lub tog raj kheej lossis ntau- lub tog raj kheej lub cav, lub tshuab synchronizer synchronizes lub synchronizer carburetor kom ntseeg tau tias cov cua ntws zoo ib yam rau txhua lub tog raj kheej.
2.Txhim kho cov kauj ruam rau Electronic Roj Txhaj Qauv
ECU Remapping: Hloov kho ECU daim ntawv qhia siv cov cuab yeej tshwj xeeb xws li Power Commander los kho cov tsis xws li kev txhaj tshuaj mem tes dav thiab lub sijhawm sib tsoo kom phim cov yam ntxwv ntawm cov pa tawm tshiab.
Oxygen sensor adaptation: Yog tias cov pa hloov pauv muaj qhov siab -flow catalytic converter, lossis yog tias cov pa oxygen sensor raug tshem tawm, yuav tsum tau hloov kho ECU lossis simulator kom tsis txhob muaj kev ceeb toom txhaum cai.
Injector Cleaning and testing: Xyuas kom meej tias lub injector tsis txhaws thiab kuaj seb lub ntim ntim tau raws li qhov yuav tsum tau ua.
IV. INTRODUCTION INTRODUCTION Cov xwm txheej tshwj xeeb thiab kev tiv thaiv
Kev hloov kho me me (piv txwv li hloov ntawm Tsuas yog Muffler lossis Exhaust Seem nkaus xwb): Yog tias tsuas yog hloov cov muffler lossis seem seem tsuas muaj qhov cuam tshuam me me ntawm lub nraub qaum, tsis muaj kev hloov ntawm carburetor lossis injector yuav tsim nyog. Txawm li cas los xij, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam cov kev hloov hauv lub zog ntawm lub cav thiab kev siv roj thiab kho lawv thaum muaj qhov tsis sib xws.
Kev siab siab - qhov chaw siab tshaj: Yog tias koj npaj yuav caij tsheb ntawm qhov siab siab, koj yuav tsum tau hloov kho huab cua ntxiv - hluav taws kub piv, vim tias huab cua nyias saum toj no yuav tsis haum rau qhov chaw tsim khoom qub.
Kev tswj hwm ib puag ncig: Hauv qee thaj chaw muaj kev txwv nruj rau kev kho cov pa tawm (xws li cov qauv suab nrov emissions). Thaum kho cov carburetor los yog roj injectors thiab injectors, peb yuav tsum xyuas kom meej raws li cov kev cai thiab tsis ua tsis tau tejyam tshuaj xyuas txhua xyoo los yog raug nplua.
Pro cov lus qhia: Kev hloov pauv ntawm cov pa tawm nrog rau kev kho lub cav cov ntsiab lus tsis zoo. Nws raug nquahu kom hloov kho los ntawm tus kws tshaj lij kws tshaj lij thiab tshawb xyuas los ntawm dynamometer lossis txoj kev kuaj kom tsis txhob muaj qhov muag tsis pom kev hloov kho thiab ua rau lub cav puas.
