Iplagi yentlantsi.
Iplagi yespark, eyaziwa ngokuba yi-fire nozzle, indima yayo kukukhulula umbane we-pulse high voltage othunyelwa yi-high voltage wire (umgca we-fire nozzle), ukuphula umoya phakathi kwee-electrode ezimbini zeplagi yespark, kunye nokuvelisa ii-electric sparks ukuze zivuthele igesi exutyiweyo kwisilinda. Iintlobo eziphambili zezi: iplagi yespark yohlobo lwe-quasi, iplagi yespark ephumayo emzimbeni, iplagi yespark yohlobo lwe-electrode, iplagi yespark yohlobo lwesihlalo, iplagi yespark yohlobo lwe-pole, iplagi yespark yohlobo lwe-spark yohlobo lwe-spark jump kunye nokunye.
Iplagi yespark ifakwe ecaleni okanye phezulu kwenjini. Iplagi yespark yokuqala iqhagamshelwe nomsasazi ngomgca wesilinda. Kwiminyaka elishumi edlulileyo, injini emotweni itshintshe kakhulu ikhoyili yokutsha kwaye iplagi yespark iqhagamshelwe ngqo. Ivolthi yokusebenza yeplagi yespark ubuncinci yi-10000V, kwaye ivolthi ephezulu iveliswa ngumbane we-12V yi-coil yokutsha, ize emva koko idluliselwe kwiplagi yespark.
Phantsi kwesenzo se-voltage ephezulu, umoya ophakathi kwe-electrode esembindini kunye ne-electrode esecaleni ye-spark plug uya ku-ionize ngokukhawuleza, wenze ii-ion ezitshajiweyo kakuhle kunye nee-electron ezitshajiweyo kakubi. Xa i-voltage phakathi kwee-electrode ifikelela kwixabiso elithile, inani lee-ion kunye nee-electron kwigesi liyanda njenge-avalanche, ukuze umoya ulahlekelwe yi-insulation yawo, kwaye isithuba senza umjelo wokukhupha, okubangela isiganeko "sokuqhekeka". Ngeli xesha, igesi yenza umzimba okhanyayo, oko kukuthi, "i-spark". Ngokwandiswa kwayo kobushushu, kukwakho nesandi "sokubethelela". Ubushushu bale spark bunokuba phezulu ukuya kwi-2000 ~ 3000℃, okwaneleyo ukutshisa umxube kwigumbi lokutsha kwesilinda.
Indlela yokuchonga iplagi yespark etshintshayo
Ukuze kuqinisekiswe ukuba iplagi yespark kufuneka itshintshwe na, inkangeleko, ukusebenza kunye nomjikelo wokutshintshwa kweplagi yespark unokuqwalaselwa kwiinkalo ezintathu:
Imilinganiselo yokubonakala kweplagi yespark
Iwotshi yoMbala:
Umbala oqhelekileyo: isiketi sesithinteli seplagi yespark kufuneka sibe mdaka okanye sibe mhlophe qhwa, nto leyo ebonisa imeko entle yokutsha.
mnyama: iplagi yespark imnyama kwaye yomile, enokuba ngumxube onamandla kakhulu kwisilinda, nto leyo ekhokelela ekutshiseni kakubi.
mhlophe: Iplagi yespark imhlophe, enokuthi ifakwe ngendlela engafanelekanga okanye iidipozithi zekhabhoni.
Eminye imibala engaqhelekanga, njengobomvu omdaka okanye umhlwa, inokubonisa ukuba iplagi ye-spark ingcolisiwe.
Ukuguguleka kwe-electrode:
I-electrode igugile kakhulu okanye inyamalale ngokupheleleyo, nto leyo ebonisa ukuba umgama wokuqhuba mkhulu kwaye awuzange utshintshwe ixesha elide.
Imeko yomzimba we-ceramic:
Into etyheli okanye into efana nodaka emzimbeni weseramikhi inokubonisa ukuba ioyile ingene kwigumbi lokutsha, kwaye kuyimfuneko ukujonga isitywino seoyile yevalvu kunye nezinye izinto.
Indlela yokugweba ukusebenza kweplagi yespark
Qalisa kwaye ukhawulezise: nokuba isithuthuthu singaqalisa ngendlela eqhelekileyo, kuyimfuneko ukujonga ukuba isantya siyaphakama na xa ucango lwepetroli olungenanto lugudileyo ukuze kujongwe ukusebenza kweplagi yespark.
Amandla okutsha: ikhabhoni eninzi kakhulu kwiplagi yentlantsi iya kuchaphazela amandla okutsha, nto leyo ebangela ubunzima ekuqaliseni okanye isantya esingazinzanga sokungaqhubi kakuhle.
Umjikelo wokutshintsha iiplagi zespark
Izinto eziqhelekileyo: njengeplagi ye-spark ye-nickel alloy, kucetyiswa ukuba ujonge iikhilomitha ezingama-20,000-30,000, kungabi ngaphezu kweekhilomitha ezingama-40,000 ukuze uyitshintshe.
Izinto ezisemgangathweni ophezulu: ezifana negolide ye-iridium, iplagi yeplatinum spark, umjikelo wokutshintshwa mde, kucetyiswa ngokubanzi ukuba ujonge kwaye utshintshe kwiikhilomitha ezingama-40,000-100,000, ngokwencwadi yesikhokelo yesithuthi esithile kunye nemeko yokwenyani.
Izixhobo zokusebenza okuphezulu: ezifana ne-double iridium spark plug, umjikelo wokutshintsha ungafikelela kwi-100,000 yeekhilomitha nangaphezulu, kwaye nezinye iimodeli zinokufikelela kwi-150-200,000 yeekhilomitha.
Qaphela *: Umjikelo wokutshintshwa kweplagi yespark unokwahluka ngokuxhomekeke kuhlobo kunye nomzekelo wenjini, kwaye kuyacetyiswa ukuba ubhekisele kwimiyalelo ethile kwincwadana yemoto.
Ngamafutshane, ukuze kuqinisekiswe ukuba iplagi yespark kufuneka itshintshwe na, ukubonakala kombala weplagi yespark, ukuguguleka kwe-electrode, imeko yomzimba we-ceramic kunye nomgama wesithuthi kunye nohlobo lwenjini kufuneka kuqwalaselwe ngokupheleleyo. Kwangaxeshanye, ukuhlolwa rhoqo kunye nokutshintshwa kweeplagi zespark kubaluleke kakhulu ekugcineni ukusebenza kakuhle kwenjini kunye nokwandisa ubomi benkonzo.
