Uyini umehluko phakathi kwama-hot spark plug nama-cold spark plug?
Okuqukethwe
Ulwazi mayelana nesilinganiso sokukhanya kwe-spark plug, esinquma ukuthi ingabe i-spark plug "iyashisa" noma "iyabanda," ibibaluleke kakhulu cishe eminyakeni eyikhulu edlule. Manje ukubaluleka kodaba kuye kwehle ngandlela thize, ngoba lawo makhandlela avunywe umenzi afakwe emotweni, noma ukuthobela kwawo kuqinisekiswa izinhlu zezingxenye ezisele.
Kodwa isihloko ngokwaso siyathakazelisa ngokombono wenkolelo-mbono yokusebenza kwenjini, ukulungiswa kwayo okuhle kakhulu kwesicelo esithile, kanye nawo wonke umuntu othanda ukuqonda nokuthuthukisa izincomo zefekthri.
Ahluke kanjani ama-spark plug?
Izincazelo zamakhandlela ashisayo nabandayo zifakwe ezimpawu zokucaphuna ngenhla nje, njengoba zinemibandela ngokwedlulele. Ikhandlela alikwazi ukubanda ngempela, lizohlaselwa ngokushesha ngemikhiqizo yamafutha kanye namanye ama-hydrocarbons, ngemva kwalokho ukwehluleka okuphelele kokushisa kuzokwenzeka.
Kuhlala kushisa embundwini wokuzihlanza, kungenye indaba uma lo mkhawulo ushintsha kancane ku-eksisi yezinga lokushisa lokusebenza.
Izimfanelo zokushisa zekhandlela zincike ezintweni eziningi:
- izakhiwo ze-electrode kanye nezinto ze-insulator;
- i-geometry yokubeka isivikelo esihlobene nomzimba, ingaphumela egumbini elivuthayo isuka engxenyeni enentambo noma iphinde iphinde ingene kuyo;
- inhlangano yokukhishwa kokushisa ezingxenyeni eziphumayo kuya emzimbeni wekhanda le-block.
Ikhandlela elilodwa kanye elifanayo, kuye ngokuthi injini ethile, lingashisa futhi libanda. Kodwa-ke, ukufana kwezixazululo zokuklama ngobuningi kancane kancane kuholela imikhiqizo enanini elijwayelekile lenombolo yokukhanya, futhi ukuphambuka kuyo kwenza kube nokwenzeka ukuhlukanisa umkhiqizo njengoshisayo noma obandayo.
Kuyashisa
Amapulaki ashisayo abhekwa njengalawo afudumala ngokushesha, ngakho awaphonswa ngesikhathi sokuqala okubandayo noma ukuphambuka ekubunjweni kwengxube. Bazophinde balethe izinkinga ezimbalwa enjinini enomfucuza kawoyela omkhulu.
Ezinjinini ezindala, lokhu bekubaluleke kakhulu. Ukungapheleli komklamo, izilinganiso eziphansi zokucindezelwa, ukungazinzi kokwakheka kwengxube, ikakhulukazi kumodi yokuqala, kuphoqe ukusetshenziswa kwamadivayisi anjalo okuthungela. Uma kungenjalo, injini ngeke ikwazi ukuqala emazingeni okushisa aphansi.
Izinga eliphansi lokuphoqelela alizange livumele amakhandlela ukuba ashise ngaphansi komthwalo omkhulu. Nakuba kwakufanele kuthathwe izinyathelo, ngokwesibonelo, ukubeka umthombo wenhlansi ekamelweni elivuthayo.
Kubanda
Lapho ipulaki elishisayo lishisa ngokweqile kusilinda, umthombo oyingozi kakhulu wezinkinga wavela ngendlela yokushisa okukhanyayo. Ngokuvamile, ukushiswa kwengxube kuqaliswa yinhlansi, futhi kunikezwa ngesikhathi esichazwe kahle ngesikhathi.
Kodwa ingxenye eshisayo izobangela ukuthungela ngokushesha, ngokushesha nje lapho ingxube yokwakheka okungaphezulu noma okuncane efanelekile ivela endaweni yayo.
Igagasi eliqhumayo lizovela khona manjalo, indawo evuthayo izohlangana ne-piston ku-counter-stroke nangaphambi kokuba ifike endaweni engaphezulu efile. Ngemva kokusebenza okufushane kule modi, injini izobhujiswa.
Kodwa impumelelo yama-serial motors enezici ezithile zamandla aphezulu, futhi ngisho nokuhambisana nokuqinisekisa ubungane bemvelo obunokuncintisana nokusebenza kahle, kuzokwandisa nakanjani umthwalo oshisayo ku-spark plug ube sezingeni elalikhona ngaphambili ezinjini zezemidlalo kuphela.
Ngakho-ke, ukumelana nokushisa ngokweqile, okungukuthi, ukususwa kokushisa okujulile, kwakudingeka ngokwesakhiwo. Amakhandlela aqala ukubanda.
Kodwa nawe awukwazi ukweqa. Ngaphandle komthamo onembile wengxube yezinhlelo zesimanje zokujova nge-elekthronikhi, ipulaki ebanda kakhulu izonciphisa izici zokuqala zenjini ebandayo.
Ngesikhathi esifanayo, ukuqina kwayo kuzokwehla, ngakho-ke, ukukhetha okunembile kwamadivaysi okushisa kuyadingeka, ngokusekelwe ezimweni zenjini. Umphumela uqukethwe enombolweni yekhathalogi yomkhiqizo. Wonke ama-analogue kufanele aqinisekise ukuhambisana nayo.
Izici zokumaka
Inombolo yokushisa ivamise ukubhalwa ngekhodi kugama lomkhiqizi. Kanye nezinye izici, i-geometric, ugesi kanye nokuba khona kwezici. Ngeshwa, alukho uhlelo olulodwa.
Ukuze uqonde ukuthi yimaphi amadivaysi ahambisana nama-analogue avela kwabanye abakhiqizi, udinga ipuleti elitholakala kalula. Inokuqhathaniswa kwamanani ezinombolo inombolo yokukhanya okunemibandela. Awukho umqondo osebenzayo ezifundweni ezinjalo, ngaphandle kokuhlukile.
Nini ukubeka ama-spark plugs abandayo nashisayo
Esinye salezi zimo ezingavamile ukukhethwa kwesizini kwamakhandlela ngenombolo yokukhanya. Abakhiqizi abaningi bezimoto bavumela lokhu ngokubonisa ukusabalala kwephuzu elilodwa noma amabili etafuleni.
Okusho ukuthi, ebusika ungabeka ikhandlela elishisayo, futhi ehlobo ubuyele kunani elibizayo noma ulivimbe, linikeze isivikelo ekushiseni okukhanyayo, uma uhlose ukusebenzisa umthamo omkhulu wenjini ekushiseni isikhathi eside.
Inani lenombolo yokukhanya
Ungaqiniseka ukuthi amakhandlela anesilinganiso sokukhanya esingu-5-6 avela ku-NGK, 6-7 avela eBosch, noma 16-20 avela eDenso azobhekana nezidingo zezinjini eziningi zabantu. Kodwa nalapha imibuzo ingase iphakame.
Kungasiphi isiqondiso inombolo ingabhekwa njengekhula, kubaluleke kangakanani ukuguqulwa kwepharamitha ngesinyathelo esincane, njalonjalo. Ithebula lezincwadi lizochaza okuningi, kodwa kungcono ukungalingi izinga lokushisa.
Ipharamitha edingekayo kade yakhethwa, kunendatshana yoku-oda kusuka kukhathalogi, futhi konke okunye kuyingozi kakhulu. Ngisho noma injini isinda endaweni engaphambi kokushisa, i-spark plug ngokwayo ingawa, futhi izingcezu zayo zizodala inkinga ku-cylinder.
Ukuxilongwa kwenjini ngokuya ngesimo samakhandlela
Lapho kunqunywa uhlobo lokungasebenzi kahle, kunconywa njalo ukuthi uvule amakhandlela kuqala. Ukubukeka kwabo kuzotshela okuningi, amacala athile atholakala ngendlela yezithombe ezimibalabala, amaqoqo azo atholakala kalula enetheni.
Umuntu anganezela kuphela ukuthi ngokuvamile akusona isimo noma umbala we-insulator othakazelisayo, kodwa ukuqhathaniswa kwawo nomakhelwane. Ikakhulukazi uma isithwebuli sikhomba kusilinda esithile.
Ngokuvamile, ukufiphala kwesivikelo kusho ukweqisa kwama-hydrocarbons noma ukushisisa okunganele. Ngokuphambene, ukuchotshozwa nokuncibilika ngezitsha zobumba ezimhlophe kuwuphawu lokushisa ngokweqile.
Kumele kuqondwe ukuthi ukukhomba izimbangela ezithile kuwumsebenzi onzima wokuxilonga, futhi akunakwenzeka ukuthi ukuxilongwa kuzokwenziwa ngombala wodwa.
Uma amakhandlela asebenzise insiza yawo eseduze, futhi akuvamile ukudlula amakhilomitha ayizinkulungwane ezingu-10-20 ngemikhiqizo eshibhile yethusi-nickel, ukubukeka kwawo kungase kubonise izinkinga ngenjini, kodwa ukuguga kwekhandlela ngokwalo. Imininingwane enjalo iyashintsha kusethi, yebo, futhi ezimweni eziningi umphumela uyamangaza.
