Yintoni iplagi ye-spark yemoto
Iplagi yespark yeyona nto iphambili kwinkqubo yokutsha kwenjini yepetroli, evelisa ispark yombane ngokukhupha i-voltage ephezulu phakathi kwee-electrodes kwaye ivuthela umxube ovuthayo kwisilinda ukuqhuba ukusebenza kwenjini.
Inkcazo yeplagi yespark kunye nemisebenzi ephambili
Inkcazelo esisiseko
I-Spark Plug (i-Spark Plug) yinxalenye ebalulekileyo yenkqubo yokutsha kwenjini yepetroli, efakwe ngaphezulu kwentloko yesilinda, enoxanduva lokungenisa umbane ombane ophezulu kwigumbi lokutsha, ngokusebenzisa i-electrode gap discharge ukuvelisa iintlantsi zombane, ukutsha umxube ocinezelweyo kwisilinda (ipetroli nomoya), ngaloo ndlela iqhuba intshukumo yepiston ukuvelisa umbane. Ngenxa yendima yayo ephambili, idla ngokubizwa ngokuba yi-"ignition artifact" okanye "heart pacemaker" yemoto.
Ingaba isebenza kanjani
I-voltage ephezulu (ngesiqhelo i-15,000 ukuya kwi-30,000 volts) idlula kwi-electrode ephakathi yeplagi ye-spark, yaphula umsantsa womoya phakathi kwe-electrode esecaleni kunye nomjelo we-ionization kwaye ikhupha i-spark.
Ubushushu bentlantsi bufikelela kwi-2000 ~ 3000℃, nto leyo enokubangela ukuba umxube uvuthe ngoko nangoko, nto leyo ebangela ukuba ukutsha kunye nokwanda kusebenze.
Ulwakhiwo kunye nohlobo lweplagi yespark
icandelo eliphambili
Kubandakanya i-wiring nut, i-insulator, i-center electrode, i-side electrode, i-metal shell, njl. Izinto ze-electrode (ezifana ne-nickel alloy, i-platinum, i-iridium, njl.njl.) zichaphazela ngokuthe ngqo ukuhanjiswa kombane kunye nobomi.
Iindidi eziqhelekileyo
Ngokwexabiso leekhalori: yahlulwe ngohlobo olubandayo (ukusasaza ubushushu obuphezulu, olufanelekileyo kwinjini enamandla aphezulu) kunye nohlobo olushushu (ukusasaza ubushushu obuphantsi, olufanelekileyo kwinjini enomlinganiselo ophantsi woxinzelelo).
ngoyilo lwe-electrode : njengepali enecala elinye, ipali enecala elininzi (njengepali enecala ezintathu ukuphucula ukuthembeka kokutsha).
ngezixhobo : iplagi yespark ye-nickel alloy (engabizi kwaye ihlala ixesha elide), iplagi yespark yegolide ye-iridium (ukusebenza okuphezulu kunye nokusetyenziswa kwamandla aphantsi), njl.
Ukubaluleka kunye nokusebenza kweeplagi zespark
Ukusebenza kwenjini
Ixesha elichanekileyo lokutsha lichaphazela ngokuthe ngqo umbane ophumayo kunye nokusebenza kakuhle kwepetroli. Ukutsha kwangethuba kakhulu kukhokelela ekuqhumeni, ukutsha emva kwexesha akwanelanga.
Iiplagi zentlantsi eziwohlokayo zinokubangela ubunzima bokuqalisa, ukushukuma okungasebenzi kakuhle, okanye ukusetyenziswa kakhulu kwepetroli.
Ukulungiswa kokusingqongileyo
Ukuze imelane namaqondo obushushu aphezulu (amawaka eedigri zeCelsius), uxinzelelo oluphezulu kunye nokugqwala kweekhemikhali, iiplagi zespark eziphezulu ziyaphuculwa zizinto ezikhethekileyo ezifana negolide yeruthenium.
Iingcebiso zolondolozo nokukhetha
Umjikelo wokutshintshwa : iplagi yespark ye-nickel alloy eqhelekileyo malunga ne-30,000 km, igolide yeplatinum/iridium ukuya kuthi ga kwi-6-100,000 km.
Umgaqo wokukhetha : kufuneka ihambelane noyilo lwenjini, iinkcukacha zokuqala zibekwe phambili, kuphephe ukutshintshwa ngokungacwangciswanga kwexabiso lobushushu okanye uhlobo lwe-electrode.
Ukuze ufumane ulwazi oluthe vetshe malunga nemodeli ethile (efana ne-NGK ruthenium gold spark plug) okanye ukusebenza kwempazamo, ungadibanisa uvavanyo lwemoto ngesandla okanye uvavanyo lobuchwephesha.
Iimpawu eziphambili zesilumkiso sokuba isithuthi kufuneka sitshintshe iplagi yaso ye-spark ziquka ubunzima bokuqalisa, ukulahleka kwamandla, isantya esingaguqukiyo sokungaqhubi kakuhle, ukunyuka okungaqhelekanga kokusetyenziswa kwepetroli, kunye nezibane zokungasebenzi kakuhle kwenjini. Ezi mpawu zihlala zinxulumene nokonakala kokusebenza kakuhle kokutsha okubangelwa ziiplagi ze-spark ezaluphalayo okanye iidipozithi zekhabhoni, kwaye kufuneka zihlolwe kwaye zitshintshwe kwangethuba ukuze kuthintelwe umonakalo ongakumbi wenjini.
Iimpawu eziphambili kunye nesiseko sokugweba
Ukuqalisa okunzima okanye okungazinzanga
Xa uqalisa ukubanda, kuyimfuneko ukudubula amaxesha amaninzi, okanye isantya senjini siyatshintshatshintsha kakhulu emva kokuqalisa. Oku kungenxa yokuguguleka kwe-electrode ye-spark plug okubangela amandla angonelanga okutsha, nto leyo engenakukwazi ukutsha okuzinzileyo kwegesi exutyiweyo.
Ukungabikho kwamandla kunye nokukhawuleza
Impendulo ye-throttle icotha xa uqhuba, kwaye amandla ehla kakhulu xa udlula okanye unyuka. Amandla okutsha kwe-spark plug anganeleyo aya kukhokelela ekutshiseni okungonelanga kwaye anciphise ukusebenza kakuhle kwenjini.
Ukungcangcazela okanye ukungcangcazela okungaqhelekanga ngexesha lokuqhuba
Ukushukuma kwenjini kubonakala xa imoto imile, okanye ukungcangcazela komzimba kuqiniswa ngesantya esiphantsi. Le meko idla ngokubangelwa yidiphozithi yekhabhoni ye-spark plug okanye i-electrode gap engaqhelekanga ebangelwa kukutsha okungalinganiyo, nto leyo ebangela ukuba umsebenzi wesilinda ungahambelani.
Ukusetyenziswa kwepetroli kunyuke kakhulu
Ukwanda ngequbuliso kokusetyenziswa kwepetroli ngaphandle kwezinye izizathu ezicacileyo (ezifana noxinzelelo olunganelanga lwamatayara) kunokunxulunyaniswa nokutsha okunganelanga kwepetroli ngenxa yokuncipha kokusebenza kakuhle kokutsha kwe-spark plug. Ukutsha okungaphelelanga kwepetroli akupheleli nje ekubeni yinkunkuma, kodwa kukwayenza mandundu ingxaki yokuqokelelwa kwekhabhoni.
Isibane sengxaki yenjini sivuliwe
Ukuba imoto yanamhlanje ibona inkqubo yokutsha engaqhelekanga, iya kuvula ukukhanya kwempazamo kwinkqubo yokuxilonga ye-OBD, kwaye kuyimfuneko ukusebenzisa izixhobo zobungcali ukuze kufundwe ikhowudi yempazamo ukuze kuqinisekiswe ngexesha.
