Ib qho pib ci ntsa iab
Lub tshuab hluav taws xob yog ib qho khoom siv hauv txhua lub cav roj uas ntsaws rau hauv lub cav lub tog raj kheej taub hau. Lub txim hluav taws xob xa hluav taws xob hluav taws xob siab mus rau ib qho kawg thiab ignites lub txim ntawm lwm qhov kawg. Lub txim taws ignites huab cua thiab roj sib tov nyob rau hauv lub cav thiab tsim combustion uas powers koj lub tsheb. Yog tsis muaj lub txim taws, koj lub tsheb yuav tsis pib.
Dab tsi yog cov khoom sib txawv ntawm cov pob hluav taws xob ua los ntawm?
Feem ntau lub txim hluav taws xob muaj tooj liab core centre electrode. Tooj liab yog cov khoom siv hluav taws xob zoo tshaj plaws, zoo dua li lwm yam khoom siv hauv cov khoom siv hluav taws xob, thiab nws kuj ua kom sov sai dua. Txawm li cas los xij, tooj liab yog mos thiab muaj qhov tsis tshua muaj melting point, yog li nws yog ib txwm them nrog nickel alloy los tiv thaiv nws. Nyob ntawm hom ntsaws, nws tuaj yeem muaj cov lus qhia platinum lossis iridium ntawm nws cov electrodes los ua kom zoo dua.
Lub hom phiaj ntawm cov hlau nyob rau hauv lub txim hluav taws xob yog dab tsi?
Cov neeg tsim khoom siv cov khoom muaj txiaj ntsig thiab lwm yam hlau nyob hauv nruab nrab thiab sab electrodes ntawm lub txim hluav taws xob. Cov hlau ua cov hluav taws xob siab los ntawm cov hluav taws xob txuas hluav taws xob mus rau lub qhov hluav taws xob, yog li nws tsim lub txim hluav taws xob thaum nws dhau los ntawm qhov sib txawv me me ntawm qhov nruab nrab thiab sab electrodes. Qhov no yog lub txim tseem ceeb uas pib cov txheej txheem combustion.
Kev siv cov hlau xws li npib tsib xee alloys, platinum thiab iridium txo qhov hnav los ntawm cov hluav taws xob hluav taws xob ntau. Cov hlau no tseem tuaj yeem pab txuas ntxiv lub sijhawm hloov pauv thiab txo qhov tsis zoo.
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm tooj liab spark plugs?
Copper spark plugs yog cov khoom siv ntau tshaj plaws thiab pheej yig tshaj plaws ntawm lub txim hluav taws xob. Txawm hais tias yuav luag txhua lub txim hluav taws xob muaj cov tub ntxhais tooj liab, ntau tus neeg xa mus rau cov hluav taws xob zoo tib yam li "tooj liab" lub txim hluav taws xob. Standard spark plugs feem ntau feature ib tug npib tsib xee alloy txheej khoom fused rau ib tug tooj liab core electrode.
Copper spark plugs khiav txias dua thiab muab lub zog ntau dua hauv kev ua haujlwm siab tsav tsheb. Lawv feem ntau yog ntsia raws li cov cuab yeej qub hauv turbocharged xyaw thiab cov cav nrog cov compression ntau dua. Copper spark plugs kuj feem ntau siv rau cov laus (ua ntej-1980s) tsheb nrog distributor-based ignition systems.
Cov khoom siv nickel alloy sab nrauv siv rau hauv tooj liab qhov hluav taws xob tsis yog ib qho nyuaj li lwm yam hlau, yog li nws hnav sai dua nyob rau hauv qhov kub siab thiab cua sov tsim hauv lub tog raj kheej lub cav. Sij hawm dhau mus, qhov hnav no tuaj yeem ua rau cov pob hluav taws xob ua rau tsis zoo thiab tsis ua haujlwm zoo li thaum lawv tshiab. Vim lawv lub neej luv luv, feem ntau cov tooj liab ntsaws ntsaws yuav tsum tau hloov txhua 20,000 mais.
Dab tsi yog qhov rub tawm ntawm platinum spark plug?
Platinum yog cov hlau hnyav dua li cov nickel alloys thiab muaj cov ntsiab lus melting ntau dua. Vim tias platinum nyuaj dua, nws khaws nws cov ntug ntse ntev dua li cov pob hluav taws xob, txog li 100,000 mais. Lub neej ua haujlwm ntev yog qhov txiaj ntsig tseem ceeb ntawm platinum spark plugs.
Lwm qhov zoo ntawm platinum spark plugs yog tias lawv khiav kub dua, uas hlawv cov deposits ntawm lub txim taws zoo dua thiab pab tiv thaiv fouling. Platinum kuj tuaj yeem tiv taus qhov kub thiab txias, ua rau cov hluav taws xob tiv taus ntau dua.
Muaj ob hom platinum spark plugs: ib leeg platinum thiab ob platinum. Ib lub platinum plug zoo li tooj liab ntsaws, nrog platinum disk welded rau qhov chaw electrode; ob lub platinum ntsaws muaj platinum disk ntawm ob qho tib si nruab nrab thiab sab electrodes.
Yuav ua li cas yog iridium spark plugs?
Iridium tau hais tias yog rau lub sij hawm nyuaj thiab yim lub sij hawm muaj zog tshaj platinum, nrog lub melting point 700 degree siab dua. Iridium spark plugs feature zoo heev electrodes thaum tuav cov yam ntxwv zoo heev. Vim lawv lub zog, iridium spark plugs kav 25% ntev dua li cov platinum spark plugs.
Iridium spark plugs feature fine-wire center electrodes tsim los ua hluav taws xob zoo dua thiab txhim kho kev siv hluav taws xob.
Cov hlau muaj nuj nqis no muaj nqi. Iridium spark plugs feem ntau yog kim tshaj plaws, txij li $ 8 txog $ 15 txhua.
Kuv yuav xaiv cov khoom siv hluav taws xob zoo tshaj plaws rau kuv lub tsheb li cas?
Txhawm rau nrhiav pom cov hluav taws xob pom zoo rau koj lub tsheb tshwj xeeb, xyuas koj tus tswv phau ntawv. Yog tias koj tus tswv phau ntawv qhia txog iridium spark plugs, tsis txhob downgrade rau platinum los yog tooj liab spark plugs; Yog hais tias koj downgrade, koj yuav ua rau lub cav tsis zoo. Koj tseem tuaj yeem tham nrog koj tus kws kho tsheb rau kev taw qhia txog kev xaiv qhov zoo tshaj plaws spark plugs rau koj lub tsheb.
