Lub txim hluav taws xob yog ib feem me me ntawm qhov pib, tab sis nws yeej txiav txim siab txog kev noj qab haus huv ntawm lub cav. Lub txim taws yog ib tug tswv cuab ntawm lub ignition mechanism. Nws txoj haujlwm yog los tsim cov nplaim taws hauv lub combustion chamber kom ignite cov combustible sib tov nyob rau hauv lub tog raj kheej. Txhawm rau siv cov lus piv txwv nrov, lub txim hluav taws xob zoo li lub flint ntawm lub teeb. Yog tias tsis muaj lub txim taws los ntawm nws, lub cav yuav tsis ignite tag nrho, thiab lub tsheb yuav tsis pib.
Nws tuaj yeem pom tias lub tshuab hluav taws xob zoo li me me, tab sis nws txiav txim siab seb lub tsheb puas tuaj yeem tsav tau lossis tsis tau, thiab seb lub tsheb puas ua haujlwm zoo. Yog tias qhov zoo ntawm lub txim hluav taws xob tsis zoo, lossis yog tias lub neej ua haujlwm dhau mus, koj lub tsheb yuav muaj kev siv roj ntau ntxiv, tsis muaj zog acceleration, thiab txawm tias me ntsis kev co. Yog li ntawd, kev siv roj ntau ntxiv tsis yog tshwm sim los ntawm kev tig lub tshuab cua txias. Xyuas kom pom tias lub tshuab hluav taws xob tsis ua haujlwm.
Yuav xaiv lub txim taws li cas
Muaj ntau ntau yam uas yuav tsum tau ua rau lub txim hluav taws xob: cov yam ntxwv thermal, tensile zog, tshav kub tsis kam, hluav taws xob conductivity, dielectric zog, sealing, thiab corrosion kuj, tag nrho cov uas yog indispensable. Vim tias qhov chaw ua haujlwm ntawm lub qhov hluav taws xob yog qhov hnyav heev, qhov ua haujlwm hluav taws xob tsawg kawg yog 10, 000 volts, thiab qhov ua haujlwm kub yog qhov nruab nrab ntawm 450 thiab 870 degree.
Yog li ntawd, thaum xaiv lub txim taws, koj tsis tuaj yeem pheej yig. Koj yuav tsum yuav cov hluav taws xob uas haum rau koj lub tsheb. Tau kawg, koj tuaj yeem yuav qhov zoo tshaj plaws yog tias muaj kev tso cai.
Dab tsi yog hom spark plugs?
Hais txog hom, nws tuaj yeem muab faib ua ntug-protruding spark plugs, electrode-type spark plugs, pole-type spark plugs, thiab lwm yam, tab sis cov no tsis cuam tshuam rau peb txhua hnub kev xaiv ntawm spark plugs. Peb yuav spark plugs txhua txhua hnub, los yog yuav spark plugs hauv internet, tej zaum yog los ntawm xaiv spark plugs ntawm cov khoom sib txawv raws li peb tus kheej qauv.
Yog li ntawd, nyob rau hauv cov nqe lus ntawm cov ntaub ntawv, lub txim plugs mas muaj xws li npib tsib xee-tooj liab alloy spark plugs, platinum spark plugs, thiab iridium kub spark plugs.
01. Nickel-tooj liab alloy spark plug
Nickel-copper alloy spark plugs yog cov feem ntau siv thiab pheej yig lub txim hluav taws xob. Nws cov khoom tseem ceeb yog npib tsib xee, uas yog hlau nplaum, nyiaj-dawb hloov pauv hlau nrog lub melting point ntawm 1453 degree.
Lub hauv paus electrode ntawm cov nickel alloy spark plug zoo li tuab, thiab qhov hluav taws xob ruaj khov yuav deteriorate tom qab siv lub sijhawm. Piv nrog rau ob lub pob hluav taws xob muaj txiaj ntsig zoo, nws muaj lub neej ua haujlwm luv tshaj plaws, thiab feem ntau yuav tsum tau hloov tom qab 20,000-30,000 mais.
02. Platinum spark plug
Platinum spark plugs yog luv nqi ntawm npib tsib xee-tooj liab alloy spark plugs thiab iridium spark plugs. Platinum yog ib qho kev hloov tsheb hloov nrog siab ntom ntom, silvery dawb xim thiab melting point ntawm 1773 degree.
Qhov kev ua tau zoo ntawm platinum spark plugs yog tshwm sim raws li ib txwm anode, cathode ablation, ignition gap hloov, thiab lwm yam., yog li nws lub neej kev pab yog li ntawm 30, 000-50, 000 kilometers.
03. Iridium spark plug
Iridium spark plugs yog tam sim no kim tshaj plaws thiab kav ntev tshaj plaws. Iridium yog cov hlau tawv heev, nyiaj-dawb, corrosion-resistant, thiab tuaj yeem tiv taus kub ntawm 2000 degree.
Vim tias tus nqi siab ntawm iridium hlau, hom lub txim hluav taws xob no yuav tsum yog tus nqi siab tshaj. Thaum nws qhov kev ua haujlwm poob qis, nws feem ntau tshwm sim raws li cathode ablation, thiab nws lub neej ua haujlwm feem ntau yog 60, 000 txog 80, 000 mais.
Ntxiv rau peb pawg saum toj no, ntau lub txim hluav taws xob tam sim no kuj hloov cov hlau sib txawv los ntawm qhov chaw electrode thiab sab electrode los ua kom cov subdivision. Xws li ob chav platinum, iridium platinum, ob chav iridium.
Los ntawm cov khoom siv dav dav, nws tuaj yeem txiav txim siab tias cov ntaub ntawv tuaj yeem muab faib ua npib tsib xee alloy, tib platinum, ib leeg iridium, ob lub platinum, iridium platinum, thiab ob chav iridium nyob rau hauv kev txiav txim ntawm kev tsis zoo. Tam sim no, lub txim hluav taws xob nrog qhov ua tau zoo tshaj plaws yog ob chav iridium spark plug, uas muaj cov yam ntxwv ntawm qhov hluav taws kub ceev, lub zog muaj zog thiab lub neej ntev. Feem ntau, ob chav iridium spark plugs tuaj yeem taug kev ntau dua 100, 000 mais.
Txawm li cas los xij, thaum yuav lub txim hluav taws xob, koj tsis tas yuav ua qhov muag tsis pom kev pheej yig dua ob chav iridium spark plugs, tsuas yog xaiv cov npe tsis tu ncua. Xws li Bosch, NGK, thiab lwm yam, koj tuaj yeem xaiv qhov uas haum rau koj lub tsheb los ntawm cov npe niaj hnub no.
Ordinary npib tsib xee alloy spark plugs muaj lub neej luv luv thiab tsis tiv taus qhov kub thiab txias li lwm cov ntsaws ntsaws. Txawm li cas los xij, kev lag luam tsheb rau cov tsev neeg niaj hnub yog txaus txaus, thiab tus nqi qis tshaj, tab sis lub voj voog hloov yog luv luv. Hais txog kev ua tau zoo, yuav tsis muaj qhov sib txawv loj. Vim hais tias cov tsev neeg zoo tib yam tsheb tsis tshua muaj qhov kub thiab txias, cia nyob ib leeg siab ceev ntau zaus, nickel alloys txaus.
Yog tias nws yog lub tsheb ua haujlwm siab lossis tus neeg siv uas nquag tsav tsheb, koj tuaj yeem xaiv iridium platinum lossis ob chav iridium spark plugs. Nyob rau hauv txoj kev no, tsis tsuas yog lub ignition efficiency thiab cov nyhuv yuav guaranteed, tab sis kuj nws muaj peev xwm tswj tau ib tug zoo kev ua hauj lwm nyob rau hauv ib tug nquag high-ceev thiab high-temperature tej yam kev mob.
Tau kawg, yog tias koj tsis muaj nyiaj luv, koj yuav tsum thov kev nplij siab. Tom qab ntawd, xaiv qhov zoo tshaj plaws spark plugs nrog ob chav iridium yog twv yuav raug hu muaj txiaj ntsig thiab tsis muaj mob, thiab tuaj yeem txo qhov zaus ntawm kev hloov.
